Stop Typing to Copilot: Use Your Voice NOW!

1
00:00:00,000 --> 00:00:02,860
Typing to co-pilot is like mailing postcards to SpaceX.

2
00:00:02,860 --> 00:00:06,600
You're communicating with a system that processes billions of parameters in milliseconds

3
00:00:06,600 --> 00:00:08,840
and you're throttling it with your thumbs.

4
00:00:08,840 --> 00:00:13,320
We speak three times faster than we type, yet we still treat AI like a polite stenographer

5
00:00:13,320 --> 00:00:15,600
instead of an intelligent collaborator.

6
00:00:15,600 --> 00:00:20,060
Every keystroke is a speed bump between your thought and the system built to automate it.

7
00:00:20,060 --> 00:00:22,760
It's the absurdity of progress outpacing behavior.

8
00:00:22,760 --> 00:00:26,240
Co-pilot is supposed to be real time, but you're forcing it to live in the era of

9
00:00:26,240 --> 00:00:27,840
QuirtyBottleNex.

10
00:00:27,840 --> 00:00:29,340
Voice isn't a convenience upgrade.

11
00:00:29,340 --> 00:00:31,220
It's the natural interface evolution.

12
00:00:31,220 --> 00:00:34,820
Spoken input meets the speed of comprehension, not the patience of typing.

13
00:00:34,820 --> 00:00:41,260
And now, thanks to Azure AI Search, GPD40's real-time API and secure M365 data, that evolution

14
00:00:41,260 --> 00:00:45,460
doesn't just hear you, it understands you instantly inside your compliance bubble.

15
00:00:45,460 --> 00:00:48,460
There's one architectural trick that makes all this possible.

16
00:00:48,460 --> 00:00:52,460
Spoiler, it's not the AI, it's what happens between your voice and its reasoning engine.

17
00:00:52,460 --> 00:00:56,340
We'll get there, but first let's talk about why typing is still wasting your time.

18
00:00:56,340 --> 00:00:58,020
Why text is the weakest link?

19
00:00:58,020 --> 00:01:02,760
Typing is slow, distracting, and deeply mismatched to how your brain wants to communicate.

20
00:01:02,760 --> 00:01:05,640
The average person types around 40 words per minute.

21
00:01:05,640 --> 00:01:10,220
The average speaker, closer to 150, that's more than a three-fold efficiency loss before

22
00:01:10,220 --> 00:01:12,620
the AI even starts processing your request.

23
00:01:12,620 --> 00:01:16,420
You could be concluding a meeting while co-pilot is still passing your keyboard input.

24
00:01:16,420 --> 00:01:19,700
The human interface hasn't just lagged, it's actively throttling the intelligence we've

25
00:01:19,700 --> 00:01:20,700
now built.

26
00:01:20,700 --> 00:01:22,060
And consider the modern enterprise.

27
00:01:22,060 --> 00:01:25,040
Teams calls dictation in word, transcriptions in one note.

28
00:01:25,040 --> 00:01:28,780
The whole Microsoft 365 ecosystem already revolves around speech.

29
00:01:28,780 --> 00:01:32,200
We talk through our work, the only thing we don't talk to is co-pilot itself.

30
00:01:32,200 --> 00:01:35,960
You narrate reports, discuss analytics, record meeting summaries, and still drop to primitive

31
00:01:35,960 --> 00:01:37,760
tapping when you finally want to query data.

32
00:01:37,760 --> 00:01:40,760
But it's like using Morse code to steer a self-driving car.

33
00:01:40,760 --> 00:01:44,280
Technically possible, culturally embarrassing.

34
00:01:44,280 --> 00:01:46,760
Typing isn't just slow, it fragments attention.

35
00:01:46,760 --> 00:01:50,000
Every time you break to phrase a query, you shift cognitive context.

36
00:01:50,000 --> 00:01:52,360
The desktop cursor becomes a mental traffic jam.

37
00:01:52,360 --> 00:01:55,400
In productivity science, this is called switch cost.

38
00:01:55,400 --> 00:01:58,960
The tiny lag that happens when your brain toggles between input modes.

39
00:01:58,960 --> 00:02:02,000
Multiply it by hundreds of co-pilot queries a day and it's the difference between flow

40
00:02:02,000 --> 00:02:03,000
and friction.

41
00:02:03,000 --> 00:02:08,240
Meanwhile, in M365 everything else has gone, hands free, teams can transcribe in real time.

42
00:02:08,240 --> 00:02:12,760
Word listens, outlook reads aloud, power automate can trigger with a voice shortcut.

43
00:02:12,760 --> 00:02:17,080
Yet the one place you actually want real conversation, querying company knowledge, still expects

44
00:02:17,080 --> 00:02:19,160
you to stop working and start typing.

45
00:02:19,160 --> 00:02:21,920
That's not assistance, that's regression disguised as convenience.

46
00:02:21,920 --> 00:02:25,400
Here's the irony, AI understands nuance better when it hears it.

47
00:02:25,400 --> 00:02:31,360
The pauses, phrasing and intonation of speech carry context that plain text strips away.

48
00:02:31,360 --> 00:02:35,920
When you type show vendor policy that's sterile, when you say it your cadence might imply urgency

49
00:02:35,920 --> 00:02:39,280
or scope, something a voice aware model can detect.

50
00:02:39,280 --> 00:02:41,800
Text removes humanity, voice restores it.

51
00:02:41,800 --> 00:02:45,920
This mismatch between intelligence and interface defines the current co-pilot experience.

52
00:02:45,920 --> 00:02:50,360
You have enterprise grade reasoning confined by 19th century communication habits.

53
00:02:50,360 --> 00:02:52,560
It's not your system that's slow, it's your thumbs.

54
00:02:52,560 --> 00:02:56,720
And if you think a faster keyboard is the answer, congratulations, you've optimized horse

55
00:02:56,720 --> 00:02:58,520
saddles for the automobile age.

56
00:02:58,520 --> 00:03:01,640
To fix that, you don't need more shortcuts or predictive text.

57
00:03:01,640 --> 00:03:04,240
You need a co-pilot that listens as fast as you think.

58
00:03:04,240 --> 00:03:07,200
That understands mid-sentence intent and response before you finish talking.

59
00:03:07,200 --> 00:03:11,080
You need a system that can hear, comprehend and act, all without demanding your eyes on

60
00:03:11,080 --> 00:03:12,400
text boxes.

61
00:03:12,400 --> 00:03:16,280
Enter voice intelligence, the evolution from request response to real conversation.

62
00:03:16,280 --> 00:03:21,480
And unlike those clunky dictation systems of the past, the new GPT40 real-time API doesn't

63
00:03:21,480 --> 00:03:24,600
wait for punctuation, it works in true dialogue speed.

64
00:03:24,600 --> 00:03:28,360
Because the problem was never intelligence, it was bandwidth and the antidote to low bandwidth

65
00:03:28,360 --> 00:03:30,520
is speaking.

66
00:03:30,520 --> 00:03:33,720
Enter voice intelligence, GPT40 real-time API.

67
00:03:33,720 --> 00:03:36,720
You've seen voice bots before, flat delayed and barely conscious.

68
00:03:36,720 --> 00:03:40,680
The kind that repeats, I didn't quite catch that until you surrender.

69
00:03:40,680 --> 00:03:43,240
That's because those systems treat audio as an afterthought.

70
00:03:43,240 --> 00:03:47,000
They wait for you to finish a sentence, transcribe it into text and then guess your meaning.

71
00:03:47,000 --> 00:03:50,000
GPT40's real-time API does not guess it listens.

72
00:03:50,000 --> 00:03:52,480
It understands what you're saying before you finish saying it.

73
00:03:52,480 --> 00:03:54,600
You're no longer conversing with a laggy stenographer.

74
00:03:54,600 --> 00:03:57,880
You're talking to a cooperative colleague who can think while you speak.

75
00:03:57,880 --> 00:04:01,520
The technical description is real-time streaming audio in and out.

76
00:04:01,520 --> 00:04:03,680
But the lived experience is more like dialogue.

77
00:04:03,680 --> 00:04:06,440
GPT40 processes intent from the waveform itself.

78
00:04:06,440 --> 00:04:08,360
It isn't translating you into text first.

79
00:04:08,360 --> 00:04:10,200
It's digesting your meaning as sound.

80
00:04:10,200 --> 00:04:11,200
Think of it as semantic hearing.

81
00:04:11,200 --> 00:04:15,280
Your co-pilot now interprets the point of your speech before your microphone fully stops vibrating.

82
00:04:15,280 --> 00:04:17,920
The model doesn't just hear words, it hears purpose.

83
00:04:17,920 --> 00:04:21,680
Picture this, an employee asks aloud, "What's our current vendor policy?"

84
00:04:21,680 --> 00:04:23,680
And gets an immediate spoken response?

85
00:04:23,680 --> 00:04:27,800
We maintain two approved suppliers, both covered under the Northwind compliance plan.

86
00:04:27,800 --> 00:04:32,560
No window switching, no menus, just immediate retrieval of corporate memory grounded in real data.

87
00:04:32,560 --> 00:04:36,360
Then she interrupts mid-sentence, "Wait, does that policy include emergency coverage?"

88
00:04:36,360 --> 00:04:37,920
And the system pivots instantly.

89
00:04:37,920 --> 00:04:40,200
No sulking, no restart, no awkward pause.

90
00:04:40,200 --> 00:04:44,520
It simply adjusts mid-stream because the session persists continuously through a low latency

91
00:04:44,520 --> 00:04:46,040
web-socket channel.

92
00:04:46,040 --> 00:04:47,400
Conversation, not command syntax.

93
00:04:47,400 --> 00:04:50,640
Now, don't confuse this with the transcription you've used in teams.

94
00:04:50,640 --> 00:04:51,640
Transcription is historical.

95
00:04:51,640 --> 00:04:53,800
It converts speech after it happens.

96
00:04:53,800 --> 00:04:55,880
GPT40 real-time is predictive.

97
00:04:55,880 --> 00:04:58,520
It starts forming meaning during your utterance.

98
00:04:58,520 --> 00:05:02,160
The computation happens as both parties talk, not sequentially.

99
00:05:02,160 --> 00:05:05,960
Is the difference between reading a book and finishing someone's sentence.

100
00:05:05,960 --> 00:05:09,760
Technically speaking, the real-time API works as a two-way audio socket.

101
00:05:09,760 --> 00:05:14,360
To stream your microphone input, it streams its synthesized voice back, sampled by sample.

102
00:05:14,360 --> 00:05:16,440
The latency is measured in 10s of a second.

103
00:05:16,440 --> 00:05:21,600
Compare that to earlier voice SDKs that queued your audio, processed it in batches, and then

104
00:05:21,600 --> 00:05:23,600
produce robotic, late replies.

105
00:05:23,600 --> 00:05:26,360
Those were glorified voice mail systems pretending to be assistance.

106
00:05:26,360 --> 00:05:28,280
This is a live duplex conversation channel.

107
00:05:28,280 --> 00:05:30,440
Your AI now breathes in sync with you.

108
00:05:30,440 --> 00:05:32,600
And yes, you can interrupt it mid-answer.

109
00:05:32,600 --> 00:05:36,880
The model rewinds its internal context and continues as though acknowledging your correction.

110
00:05:36,880 --> 00:05:40,240
It's less like a chatbot and more like an exceptionally polite panelist.

111
00:05:40,240 --> 00:05:44,640
It listens, anticipates, speaks, pauses when you speak, and carries state forward.

112
00:05:44,640 --> 00:05:47,440
The beauty is that this intelligence doesn't exist in isolation.

113
00:05:47,440 --> 00:05:51,920
The GPT portion supplies generative reasoning, but the real-time layer supplies timing and

114
00:05:51,920 --> 00:05:52,920
tone.

115
00:05:52,920 --> 00:05:54,680
It turns cognitive power into conversation.

116
00:05:54,680 --> 00:05:55,920
You aren't formatting prompts.

117
00:05:55,920 --> 00:05:57,120
You're holding dialogue.

118
00:05:57,120 --> 00:06:00,920
It feels human not because of personality scripts, but because latency finally dropped

119
00:06:00,920 --> 00:06:02,520
below your perception threshold.

120
00:06:02,520 --> 00:06:04,600
For enterprise use, this changes everything.

121
00:06:04,600 --> 00:06:09,600
Action, sales team squaring, CRM data, hands-free mid-call, or engineers reviewing project documents

122
00:06:09,600 --> 00:06:11,520
via voice while their hands handle hardware.

123
00:06:11,520 --> 00:06:13,080
The friction evaporates.

124
00:06:13,080 --> 00:06:17,400
And because this API outputs audio as easily as it consumes it, co-pilot gains a literal

125
00:06:17,400 --> 00:06:20,520
voice, context aware, emotionally neutral, and fast.

126
00:06:20,520 --> 00:06:23,560
Of course, hearing without knowledge is still ignorance at speed.

127
00:06:23,560 --> 00:06:25,040
Recognition must be paired with retrieval.

128
00:06:25,040 --> 00:06:26,560
The voice interface is the ear?

129
00:06:26,560 --> 00:06:28,120
Yes, but an ear needs a brain.

130
00:06:28,120 --> 00:06:32,600
GPT 40 real-time gives the co-pilot presence, cadence, and intuition.

131
00:06:32,600 --> 00:06:35,520
As your AI search gives it memory, grounding, and precision.

132
00:06:35,520 --> 00:06:38,680
Combine them and you move from clever echo chamber to informed colleague.

133
00:06:38,680 --> 00:06:42,400
So the intelligent listener has arrived, but to make it useful in business, it must know

134
00:06:42,400 --> 00:06:46,360
your data, the internal governed, securely indexed core of your organization.

135
00:06:46,360 --> 00:06:49,960
That's where the next layer takes over, the part of the architecture that remembers everything

136
00:06:49,960 --> 00:06:51,840
without violating anything.

137
00:06:51,840 --> 00:06:53,160
Time to meet the brain.

138
00:06:53,160 --> 00:06:56,920
As your AI search, where retrieval finally joins generation.

139
00:06:56,920 --> 00:07:00,720
The brain, as your AI search and the rag pattern, let's be clear.

140
00:07:00,720 --> 00:07:05,000
GPT 40 may sound articulate, but left alone it's an eloquent goldfish.

141
00:07:05,000 --> 00:07:07,200
No memory, no context, endless confidence.

142
00:07:07,200 --> 00:07:10,640
To make it useful, you have to tether that generative brilliance to real data.

143
00:07:10,640 --> 00:07:14,280
Your actual M365 content stored, governed, and indexed.

144
00:07:14,280 --> 00:07:19,160
That tether is the retrieval-augmented generation pattern, mercifully abbreviated to rag.

145
00:07:19,160 --> 00:07:23,360
It's the technique that converts an AI from a talkative guesser into a knowledgeable colleague.

146
00:07:23,360 --> 00:07:24,360
Here's the structure.

147
00:07:24,360 --> 00:07:28,320
In rag, every answer begins with retrieval, not imagination.

148
00:07:28,320 --> 00:07:31,040
The model doesn't just think harder, it looks up evidence.

149
00:07:31,040 --> 00:07:35,360
Imagine a librarian who drafts the essay only after fetching the correct shelf of books.

150
00:07:35,360 --> 00:07:38,720
As your AI search is that librarian, fast, literal, and meticulous.

151
00:07:38,720 --> 00:07:42,840
When you integrate it with GPT 40, you're essentially plugging a language model into your

152
00:07:42,840 --> 00:07:43,960
corporate brain.

153
00:07:43,960 --> 00:07:48,840
As your AI search works like this, your files, word docs, PDFs, sharepoint items, live peacefully

154
00:07:48,840 --> 00:07:50,200
in Azure Blob storage.

155
00:07:50,200 --> 00:07:54,680
The search service ingests that material, enriches it with AI, and builds multiple kinds

156
00:07:54,680 --> 00:07:57,680
of indexes, including semantic and vector indexes.

157
00:07:57,680 --> 00:08:02,720
Mathematical fingerprints of meaning, each sentence, each paragraph, becomes a coordinate

158
00:08:02,720 --> 00:08:04,440
in high-dimensional space.

159
00:08:04,440 --> 00:08:07,000
When you ask a question, the system doesn't do keyword matching.

160
00:08:07,000 --> 00:08:11,080
It runs a similarity search through that semantic galaxy, finding entries whose meaning

161
00:08:11,080 --> 00:08:13,560
vectors sit closest to your query.

162
00:08:13,560 --> 00:08:15,920
Think of it like DNA matching, but for language.

163
00:08:15,920 --> 00:08:20,800
A policy document about employee perks and another about compensation benefits might use

164
00:08:20,800 --> 00:08:25,480
totally different words, yet in vector space they share 99% genetic overlap.

165
00:08:25,480 --> 00:08:29,200
That's why rack-based systems can interpret natural speech like, does our company still

166
00:08:29,200 --> 00:08:31,160
cover scuba lessons?

167
00:08:31,160 --> 00:08:35,280
And fetch the relevant HR benefits clause without you ever mentioning the phrase "perc

168
00:08:35,280 --> 00:08:36,280
allowance".

169
00:08:36,280 --> 00:08:39,800
In plain English, your data learns to recognize itself faster than your compliance officer

170
00:08:39,800 --> 00:08:40,800
finds disclaimers.

171
00:08:40,800 --> 00:08:45,840
GPT 40 then takes those relevant snippets, usually a few sentences from the top matches,

172
00:08:45,840 --> 00:08:47,920
and fuses them into the generative response.

173
00:08:47,920 --> 00:08:53,120
The outcome feels human, but remains factual, grounded in what Azure AI search retrieved.

174
00:08:53,120 --> 00:08:57,440
No hallucinations about imaginary insurance plans, no invented policy names, no alternative

175
00:08:57,440 --> 00:08:58,760
facts.

176
00:08:58,760 --> 00:09:02,200
Security people love this pattern because grounding preserves control boundaries.

177
00:09:02,200 --> 00:09:06,000
The AI never has unsupervised access to the entire repository.

178
00:09:06,000 --> 00:09:10,760
It only sees the materials pass through retrieval even better, as your AI search supports

179
00:09:10,760 --> 00:09:12,240
confidential computing.

180
00:09:12,240 --> 00:09:16,920
Meaning those indexes can be processed inside hardware-based secure enclave.

181
00:09:16,920 --> 00:09:20,040
Voice transcripts or HR docs aren't just in the cloud.

182
00:09:20,040 --> 00:09:23,960
They're inside encrypted virtual machines that even Microsoft engineers can't peek into.

183
00:09:23,960 --> 00:09:27,280
That's how you discuss sensitive benefits by voice without violating your own governance

184
00:09:27,280 --> 00:09:28,280
rules.

185
00:09:28,280 --> 00:09:32,280
Now, to make rags sustainable in enterprise workflows, you insert a proxy, a modest but

186
00:09:32,280 --> 00:09:35,840
decisive layer between GPT 40 and Azure AI search.

187
00:09:35,840 --> 00:09:39,760
This middle tier manages tool calls, performs the retrieval, sanitizes outputs, and logs

188
00:09:39,760 --> 00:09:41,280
activity for compliance.

189
00:09:41,280 --> 00:09:43,880
GPT 40 never connects directly to your search index.

190
00:09:43,880 --> 00:09:47,040
It requests a search tool which the proxy executes on its behalf.

191
00:09:47,040 --> 00:09:50,720
You gain auditing, throttling, and policy enforcement in one move.

192
00:09:50,720 --> 00:09:53,560
It's the architectural version of talking through legal councils.

193
00:09:53,560 --> 00:09:56,080
Safe, accountable, and occasionally necessary.

194
00:09:56,080 --> 00:09:58,760
This proxy also allows multi-tenant setups.

195
00:09:58,760 --> 00:10:03,320
Different departments finance, HR, engineering can share the same AI core while maintaining

196
00:10:03,320 --> 00:10:05,400
isolated data scopes.

197
00:10:05,400 --> 00:10:07,320
Separation of concerns equals separation of risk.

198
00:10:07,320 --> 00:10:10,600
If marketing shouts, what's our expense limit for conferences?

199
00:10:10,600 --> 00:10:14,480
The AI brain only rummages through marketing's index, not finances ledger.

200
00:10:14,480 --> 00:10:17,960
The retrieval rules define not only what's relevant, but also what's permitted.

201
00:10:17,960 --> 00:10:20,400
Technically, that's the genius of Azure AI search.

202
00:10:20,400 --> 00:10:22,000
It's not just a search engine.

203
00:10:22,000 --> 00:10:25,000
It's a controlled memory system with role-based access baked in.

204
00:10:25,000 --> 00:10:29,440
You can enrich data during ingestion, attach metadata tags like confidential and filter

205
00:10:29,440 --> 00:10:30,720
queries accordingly.

206
00:10:30,720 --> 00:10:33,880
The rag layer respects those boundaries automatically.

207
00:10:33,880 --> 00:10:38,200
Generative AI remains charmingly oblivious to your internal hierarchies, as your enforces

208
00:10:38,200 --> 00:10:39,480
them behind the curtain.

209
00:10:39,480 --> 00:10:41,880
This organized amnesia serves governance well.

210
00:10:41,880 --> 00:10:46,080
If a department deletes a document or revokes access, the next indexing run removes it

211
00:10:46,080 --> 00:10:47,400
from retrieval candidates.

212
00:10:47,400 --> 00:10:50,640
The model literally forgets what it's no longer authorized to know.

213
00:10:50,640 --> 00:10:54,920
Compliance offers a dream of systems that forget on command and rag delivers that elegantly.

214
00:10:54,920 --> 00:10:56,560
The performance side is just as elegant.

215
00:10:56,560 --> 00:11:00,120
Traditional keyword search crawls indexes sequentially.

216
00:11:00,120 --> 00:11:05,400
As your AI search employs vector similarity, semantic ranking, and hybrid scoring to retrieve

217
00:11:05,400 --> 00:11:08,360
the most contextually appropriate content first.

218
00:11:08,360 --> 00:11:13,240
GPT-4O is then handed a compact high fidelity context window, no noise, no relevant fluff,

219
00:11:13,240 --> 00:11:14,960
making responses faster and cheaper.

220
00:11:14,960 --> 00:11:19,200
You're essentially feeding it curated intelligence instead of letting it rummage through raw data.

221
00:11:19,200 --> 00:11:22,400
And for those who enjoy buzzwords, yes, this is enterprise grounding.

222
00:11:22,400 --> 00:11:24,080
But what matters is reliability.

223
00:11:24,080 --> 00:11:28,600
When co-pilot answers a policy question, it sights the exact source file and keeps the phrasing

224
00:11:28,600 --> 00:11:29,600
legally accurate.

225
00:11:29,600 --> 00:11:34,480
Unlike consumer grade assistants that invent quotes, this brain references your actual compliance

226
00:11:34,480 --> 00:11:35,480
text.

227
00:11:35,480 --> 00:11:41,200
In other words, your AI finally behaves like an employee who reads the manual before answering,

228
00:11:41,200 --> 00:11:45,440
combined that dependable retrieval with GPT-4O s conversational flow and you get something

229
00:11:45,440 --> 00:11:46,440
uncanny.

230
00:11:46,440 --> 00:11:49,200
A voice interface that s both chatty and certified.

231
00:11:49,200 --> 00:11:51,960
It talks like a human, but things like SharePoint with an attitude problem.

232
00:11:51,960 --> 00:11:55,880
Now we have the architectures nervous system, the brain that remembers cross checks and protects.

233
00:11:55,880 --> 00:12:00,520
But a brain without an output device is merely a server-farm day dreaming in silence.

234
00:12:00,520 --> 00:12:02,120
Information retrieval is impressive?

235
00:12:02,120 --> 00:12:03,120
Sure.

236
00:12:03,120 --> 00:12:08,440
You can see the results of the brain's response to speak it aloud and do so within corporate policy.

237
00:12:08,440 --> 00:12:11,440
Fortunately, Microsoft already supplied the vocal chords.

238
00:12:11,440 --> 00:12:17,240
Next comes the mouth, integrating this carefully trained mind with M365 s voice layer so it can

239
00:12:17,240 --> 00:12:20,840
speak responsibly, even when you whisper the difficult questions.

240
00:12:20,840 --> 00:12:24,360
The mouth, M365 integration for secure voice interaction.

241
00:12:24,360 --> 00:12:28,240
Now that the architecture has a functioning brain, it needs a mouth, an output mechanism

242
00:12:28,240 --> 00:12:31,840
that speaks policy-compliant wisdom without spilling confidential secrets.

243
00:12:31,840 --> 00:12:37,080
Where the theoretical meets the practical and GPT-4O s linguistic virtuosity finally learns

244
00:12:37,080 --> 00:12:39,440
to say real things to real users securely.

245
00:12:39,440 --> 00:12:41,480
Here s the chain of custody for your voice.

246
00:12:41,480 --> 00:12:46,480
You speak into a co-pilot studio agent or a custom power app embedded in teams.

247
00:12:46,480 --> 00:12:50,880
Your words convert into sound signals, beautifully untyped, mercifully fast, and those streams are

248
00:12:50,880 --> 00:12:53,320
routed through a secure proxy layer.

249
00:12:53,320 --> 00:12:58,160
The proxy connects to Azure AI search for retrieval and grounding, then funnels the curated

250
00:12:58,160 --> 00:13:01,560
knowledge back through GPT-4O real-time for immediate voice response.

251
00:13:01,560 --> 00:13:04,320
You ask, what's our vacation carryover rule?

252
00:13:04,320 --> 00:13:08,360
And within a breath, co-pilot politely answers aloud citing the HR policy stored deep in

253
00:13:08,360 --> 00:13:09,360
SharePoint.

254
00:13:09,360 --> 00:13:13,520
The full loop from mouth to mind and back finishes before your coffee cools.

255
00:13:13,520 --> 00:13:17,000
What s elegant here is the division of labor, the power platform, co-pilot studio power

256
00:13:17,000 --> 00:13:20,520
apps power automate handles the user experience.

257
00:13:20,520 --> 00:13:24,560
Think microphones, buttons, teams interfaces, adaptive cards.

258
00:13:24,560 --> 00:13:27,120
Azure handles cognition retrieval reasoning generation.

259
00:13:27,120 --> 00:13:30,560
In other words, Microsoft separated presentation from intelligence.

260
00:13:30,560 --> 00:13:33,960
Your power app never carries proprietary model keys or search credentials.

261
00:13:33,960 --> 00:13:36,880
It just speaks to the proxy the same way you speak to co-pilot.

262
00:13:36,880 --> 00:13:39,600
That s why this architecture scales without scaring the security team.

263
00:13:39,600 --> 00:13:42,880
Speaking of security, this is where governance flexes its muscles.

264
00:13:42,880 --> 00:13:46,840
Every syllable of that interaction, your voice, its transcription, the AI s response is

265
00:13:46,840 --> 00:13:51,160
covered by data loss prevention policies, role-based access controls, and confidential

266
00:13:51,160 --> 00:13:53,320
computing protections.

267
00:13:53,320 --> 00:13:56,120
Voice data isn t flitting around like stray packets.

268
00:13:56,120 --> 00:13:58,200
It s encrypted in transit.

269
00:13:58,200 --> 00:14:02,080
It s inside trusted execution environments and discarded per policy.

270
00:14:02,080 --> 00:14:03,840
The pipeline doesn t really answer securely.

271
00:14:03,840 --> 00:14:05,880
It remains secure while answering.

272
00:14:05,880 --> 00:14:11,200
When Microsoft retired speaker recognition in 2025, many panicked about identity verification.

273
00:14:11,200 --> 00:14:13,000
How will the system know who speaking?

274
00:14:13,000 --> 00:14:15,240
Easily, by context, not by biometrics.

275
00:14:15,240 --> 00:14:20,280
Co-pilot integrates with your Microsoft Entra identity, teams presence, and session metadata.

276
00:14:20,280 --> 00:14:24,360
The system knows who you are because you re authenticated into the workspace, not because

277
00:14:24,360 --> 00:14:26,400
it memorized your vocal chords.

278
00:14:26,400 --> 00:14:30,880
That means no personal voice enrollment, no biometric liability, and no new privacy paperwork.

279
00:14:30,880 --> 00:14:34,560
The authentication wraps around the session itself, so the voice experience remains as compliant

280
00:14:34,560 --> 00:14:36,040
as the rest of m365.

281
00:14:36,040 --> 00:14:37,480
Consider what happens technically.

282
00:14:37,480 --> 00:14:40,560
The voice packet you generate enters a confidential virtual machine.

283
00:14:40,560 --> 00:14:43,720
The secure sandbox where GPT-4O performs its reasoning.

284
00:14:43,720 --> 00:14:49,520
There, the model accesses only intermediate representations of your data, not raw files.

285
00:14:49,520 --> 00:14:54,240
The retrieval logic runs server-side inside Azure's confidential computing framework.

286
00:14:54,240 --> 00:14:57,200
Even Microsoft engineers can't peek inside those enclave.

287
00:14:57,200 --> 00:15:01,320
So yes, even your whispered HR complaint about that new mandatory team building exercise

288
00:15:01,320 --> 00:15:04,200
is processed under full compliance certification.

289
00:15:04,200 --> 00:15:06,120
Romantic in a bureaucratic sort of way.

290
00:15:06,120 --> 00:15:09,840
For enterprises obsessed with regulation, and who isn't now, this matters.

291
00:15:09,840 --> 00:15:15,980
GDPR, HIPAA, ISO 27001, SOC2, they remain intact because every part of that voice loop respects

292
00:15:15,980 --> 00:15:19,400
boundaries already defined in m365 data governance.

293
00:15:19,400 --> 00:15:24,040
Speech becomes just another modality of query, subject to the same auditing and e-discovery

294
00:15:24,040 --> 00:15:25,600
rules as e-mail or chat.

295
00:15:25,600 --> 00:15:30,320
In fact, transcripts can be automatically logged in Microsoft purview for compliance review.

296
00:15:30,320 --> 00:15:33,120
The future of internal accountability, it talks back.

297
00:15:33,120 --> 00:15:34,400
Now about policy control.

298
00:15:34,400 --> 00:15:38,680
Each voice interaction adheres to your organization's DLP filters and information barriers.

299
00:15:38,680 --> 00:15:42,920
The model knows not to read classified content allowed to unauthorize listeners.

300
00:15:42,920 --> 00:15:45,080
It won't summarize the board minutes for an intern.

301
00:15:45,080 --> 00:15:49,140
The compliance layer acts like an invisible moderator quietly ensuring conversation stays

302
00:15:49,140 --> 00:15:50,140
appropriate.

303
00:15:50,140 --> 00:15:53,920
Every utterance is context aware, permission checked, and policy filtered before synthesis.

304
00:15:53,920 --> 00:15:56,880
Underneath, the architecture relies on the proxy layer again.

305
00:15:56,880 --> 00:15:58,200
Remember it from the rag setup?

306
00:15:58,200 --> 00:16:01,540
It's still the diplomatic translator between your conversational AI and everything it's

307
00:16:01,540 --> 00:16:02,800
not supposed to see.

308
00:16:02,800 --> 00:16:07,340
That same proxy sanitizes response metadata, logs timing metrics, even tags outputs for

309
00:16:07,340 --> 00:16:08,340
audit trails.

310
00:16:08,340 --> 00:16:12,760
It ensures your friendly chatbot doesn't accidentally become a data exfiltration service.

311
00:16:12,760 --> 00:16:17,440
Practically, this design means you can deploy, voice-enabled agents across departments without

312
00:16:17,440 --> 00:16:19,040
rewriting compliance rules.

313
00:16:19,040 --> 00:16:24,360
HR, finance, legal, all maintain their data partitions, yet share one listening co-pilot.

314
00:16:24,360 --> 00:16:27,880
Each department's knowledge base sits behind its own retrieval endpoints.

315
00:16:27,880 --> 00:16:33,000
Users hear seamless, unified answers, but under the hood, every sentence originates from

316
00:16:33,000 --> 00:16:35,280
a policy scoped domain.

317
00:16:35,280 --> 00:16:39,640
And because all front-end logic resides in power platform, there's no need for heavy coding.

318
00:16:39,640 --> 00:16:44,280
Makers can build team's extensions, mobile apps, or agent experiences that behave identically.

319
00:16:44,280 --> 00:16:48,240
The real-time API acts as the interpreter, the search index acts as memory and governance

320
00:16:48,240 --> 00:16:49,400
acts as conscience.

321
00:16:49,400 --> 00:16:53,040
The trio forms the digital equivalent of thinking before speaking, finally a machine that

322
00:16:53,040 --> 00:16:54,240
does it automatically.

323
00:16:54,240 --> 00:16:59,040
So yes, your AI can now hear, think, and speak responsibly all wrapped in existing enterprise

324
00:16:59,040 --> 00:17:00,360
compliance.

325
00:17:00,360 --> 00:17:01,840
Voice has become more than input.

326
00:17:01,840 --> 00:17:04,680
It's a policy-compliant user interface.

327
00:17:04,680 --> 00:17:07,080
Users don't just interact, they converse securely.

328
00:17:07,080 --> 00:17:09,000
The machine doesn't just reply, it behaves.

329
00:17:09,000 --> 00:17:12,320
Now that the system can talk back like a well-briefed colleague, the next question writes

330
00:17:12,320 --> 00:17:16,840
itself, "How do you actually deploy this conversational knowledge layer across your environment

331
00:17:16,840 --> 00:17:19,880
without tripping over API limits or governance gates?"

332
00:17:19,880 --> 00:17:23,480
Because the talking brain is nice, a deployed one is transformative.

333
00:17:23,480 --> 00:17:27,720
Deploying the voice-driven knowledge layer, time to leave theory and start deployment, you

334
00:17:27,720 --> 00:17:30,800
have admired the architecture long enough, now assemble it.

335
00:17:30,800 --> 00:17:35,440
Fortunately, the process doesn't demand secret incantations or lines of Python, no mortal

336
00:17:35,440 --> 00:17:36,720
can maintain.

337
00:17:36,720 --> 00:17:38,640
It's straightforward engineering elegance.

338
00:17:38,640 --> 00:17:41,080
Four logical steps, zero hand-waving.

339
00:17:41,080 --> 00:17:43,240
Step one, prepare your data in blob storage.

340
00:17:43,240 --> 00:17:47,400
Azure doesn't need your internal files sprinkled across a thousand SharePoint libraries.

341
00:17:47,400 --> 00:17:51,720
Consolidate the source corpus, policy documents, procedure manuals, FAQs, technical standards,

342
00:17:51,720 --> 00:17:52,880
into structured containers.

343
00:17:52,880 --> 00:17:54,200
That's your raw fuel.

344
00:17:54,200 --> 00:17:57,000
Tag files, cleanly, department, sensitivity, version.

345
00:17:57,000 --> 00:18:00,520
When ingestion starts, you want search to know what it's digesting, not choke on duplicates

346
00:18:00,520 --> 00:18:01,520
from 2018.

347
00:18:01,520 --> 00:18:03,560
Step two, create your indexed search.

348
00:18:03,560 --> 00:18:08,760
In Azure AI search, configure a hybrid index that mixes vector and semantic ranking.

349
00:18:08,760 --> 00:18:11,440
Vector search grants contextual intelligence.

350
00:18:11,440 --> 00:18:13,160
Semantic ranking ensures precision.

351
00:18:13,160 --> 00:18:15,120
Indexing isn't a one and done exercise.

352
00:18:15,120 --> 00:18:18,760
Configure automatic refresh schedules, so new HR guidelines appear before someone files a

353
00:18:18,760 --> 00:18:21,000
ticket asking where their dental plan went.

354
00:18:21,000 --> 00:18:25,240
Each pipeline run re-embeds the text, recomputes vectors and updates the semantic layers.

355
00:18:25,240 --> 00:18:28,240
Your data literally keeps itself fluent in context.

356
00:18:28,240 --> 00:18:30,440
Step three, build the middle tier proxy.

357
00:18:30,440 --> 00:18:34,760
Too many architects skip this and then email me asking why their co-pilot leaks telemetry

358
00:18:34,760 --> 00:18:35,960
like a rookie intern.

359
00:18:35,960 --> 00:18:38,440
The proxy mediates all real-time API calls.

360
00:18:38,440 --> 00:18:42,360
It listens to voice input from the power platform, triggers retrieval functions in Azure

361
00:18:42,360 --> 00:18:47,080
AI search, merges grounding data and relays responses back to GPT-40.

362
00:18:47,080 --> 00:18:51,480
This is also where you insert governance logic, rate limits, logging, user impersonation rules

363
00:18:51,480 --> 00:18:52,840
and compliance tagging.

364
00:18:52,840 --> 00:18:57,440
Think of it as the diplomatic attache between real-time intelligence and enterprise paranoia.

365
00:18:57,440 --> 00:19:02,000
Step four, connect the front end, in co-pilot studio or power apps create the voice UI.

366
00:19:02,000 --> 00:19:05,120
Assign it input and output nodes bound to your proxy endpoints.

367
00:19:05,120 --> 00:19:08,200
You don't stream raw audio into GPT directly.

368
00:19:08,200 --> 00:19:10,600
You stream through controlled channels.

369
00:19:10,600 --> 00:19:14,600
Here are the real-time API tokens in Azure, not in the app so no-maker accidentally hard

370
00:19:14,600 --> 00:19:16,600
codes your secret keys into a demo.

371
00:19:16,600 --> 00:19:18,760
The voice flows under policy supervision.

372
00:19:18,760 --> 00:19:23,760
When done correctly, your co-pilot speaks through an encrypted intercom, not an open mic.

373
00:19:23,760 --> 00:19:27,720
Now about constraints, power platform may tempt you to handle the whole flow inside one

374
00:19:27,720 --> 00:19:28,720
low-code environment.

375
00:19:28,720 --> 00:19:29,720
Don't.

376
00:19:29,720 --> 00:19:32,480
The platform enforces API request limits.

377
00:19:32,480 --> 00:19:35,880
40,000 per user per day, 250,000 per flow.

378
00:19:35,880 --> 00:19:39,480
A chatty voice assistant will burn through that quota before lunch, heavy lifting belongs

379
00:19:39,480 --> 00:19:40,480
in Azure.

380
00:19:40,480 --> 00:19:44,360
Your power app orchestrates, Azure executes, let the cloud absorb the audio workload so

381
00:19:44,360 --> 00:19:47,800
your flows remain decisive instead of throttled.

382
00:19:47,800 --> 00:19:49,920
A quick reality check for makers.

383
00:19:49,920 --> 00:19:53,720
Building this layer won't look like writing a bot, it'll feel like provisioning infrastructure.

384
00:19:53,720 --> 00:19:57,760
Your wiring ears to intelligence to compliance, not gluing dialogues together, business

385
00:19:57,760 --> 00:20:00,720
users still hear a simple co-pilot that talks.

386
00:20:00,720 --> 00:20:05,080
But under the hood, it's a distributed system balancing cognition, security and bandwidth.

387
00:20:05,080 --> 00:20:08,920
And since maintenance always determines success after applause fades, planned-governed

388
00:20:08,920 --> 00:20:10,600
automation from day one.

389
00:20:10,600 --> 00:20:14,040
Azure AI Search supports event-driven re-indexing.

390
00:20:14,040 --> 00:20:17,080
Hook it to your document libraries so updates trigger automatically.

391
00:20:17,080 --> 00:20:21,440
Add purview scanning rules to confirm nothing confidential sneaks into retrieval.

392
00:20:21,440 --> 00:20:25,320
Combine that with audit trails in the proxy layer, and you'll know not only what the AI said

393
00:20:25,320 --> 00:20:26,680
but why it said it.

394
00:20:26,680 --> 00:20:28,800
Real-world examples clarify the payoff.

395
00:20:28,800 --> 00:20:31,160
HR teams query handbooks by voice.

396
00:20:31,160 --> 00:20:33,440
How many vacation days carry over this year?

397
00:20:33,440 --> 00:20:36,120
IT staff troubleshoot policies mid-call.

398
00:20:36,120 --> 00:20:38,000
What's the standard laptop image?

399
00:20:38,000 --> 00:20:42,800
Legal reviews compliance statements orally, retrieving source citations instantly.

400
00:20:42,800 --> 00:20:47,160
The latency is low enough to feel conversational, yet the pipeline remains rule-bound.

401
00:20:47,160 --> 00:20:51,960
Every exchange leaves a traceable log, samplers of knowledge, not breadcrumbs of liability.

402
00:20:51,960 --> 00:20:56,320
From a productivity lens, this system closes the cognition gap between thought and action.

403
00:20:56,320 --> 00:20:58,320
Typing created delay, speed removes it.

404
00:20:58,320 --> 00:21:02,800
The rag architecture ensures factual grounding, confidential computing enforces safety.

405
00:21:02,800 --> 00:21:05,080
The real-time API brings speed.

406
00:21:05,080 --> 00:21:08,480
Collectively, they form what amounts to an enterprise oral tradition.

407
00:21:08,480 --> 00:21:11,560
The company can literally speak its knowledge back to employees.

408
00:21:11,560 --> 00:21:16,120
And that's the transformation, not a prettier interface, but the birth of operational conversation.

409
00:21:16,120 --> 00:21:18,840
Machines participating legally, securely, instantly.

410
00:21:18,840 --> 00:21:22,280
The modern professionals tools have evolved from click to type to talk.

411
00:21:22,280 --> 00:21:26,120
Next time you see someone pause mid-meeting to hammer out a copilot query, you're watching

412
00:21:26,120 --> 00:21:28,000
latency disguised as habit.

413
00:21:28,000 --> 00:21:29,640
Politely suggest evolution.

414
00:21:29,640 --> 00:21:32,560
So yes, the deployment checklist fits on one whiteboard.

415
00:21:32,560 --> 00:21:35,880
Prepare, index proxy, connect, govern, maintain.

416
00:21:35,880 --> 00:21:37,880
Behind each verbalize an Azure service.

417
00:21:37,880 --> 00:21:40,800
Together they give copilot lungs memory and manners.

418
00:21:40,800 --> 00:21:44,480
You've now built a knowledge layer that listens, speaks, and keeps secrets better than

419
00:21:44,480 --> 00:21:46,520
your average conference call attendee.

420
00:21:46,520 --> 00:21:51,320
The only remaining step is behavioral, getting humans to stop typing like it's 2003, and

421
00:21:51,320 --> 00:21:54,520
start conversing like it's the future they already licensed.

422
00:21:54,520 --> 00:21:56,160
The simple human upgrade.

423
00:21:56,160 --> 00:22:00,120
Voice is not a gadget, it's the missing sense your AI finally developed.

424
00:22:00,120 --> 00:22:05,360
The fastest, most natural, and thanks to Azure's governance, the most secure way to interact

425
00:22:05,360 --> 00:22:06,880
with enterprise knowledge.

426
00:22:06,880 --> 00:22:11,560
With GPT-4O streaming intellect, Azure AI, search, grounding truth, and M365 governing

427
00:22:11,560 --> 00:22:15,880
behavior, you're no longer typing at copilot, you're collaborating with it in real time.

428
00:22:15,880 --> 00:22:20,320
Typing to copilot is like sending smoke signals to outlook, technically feasible, historically

429
00:22:20,320 --> 00:22:21,880
interesting, utterly pointless.

430
00:22:21,880 --> 00:22:23,440
The smarter move is auditory.

431
00:22:23,440 --> 00:22:26,840
Build the layer, wire the proxy, and speak your workflows into motion.

432
00:22:26,840 --> 00:22:33,080
If this explanation saved you 10 key strokes or 10 minutes, repay the efficiency debt, subscribe.

433
00:22:33,080 --> 00:22:37,800
Enable notifications so the next architectural deep dive arrives automatically, like a scheduled

434
00:22:37,800 --> 00:22:38,880
backup for your brain.

435
00:22:38,880 --> 00:22:39,960
Stop typing, start talking.
