0:00GPT-Live-1What's on your mind?
0:01Dessa AIum so I have a question about
0:05Dessa AIhow
0:05Dessa AIchat GPT can learn and get smarter
0:08Dessa AIso basically I just want to know
0:10GPT-Live-1That's a good one.
0:11Dessa AIwhat what
0:14Dessa AIwhat are things that could make chat
0:16Dessa AIGPT smarter and what effects could that
0:18Dessa AIhave on the researchers in the field?
0:23GPT-Live-1Let me check a
0:23GPT-Live-1few angles.
0:25GPT-Live-1There are a few big ways chat
0:26GPT-Live-1UPT style systems can get smarter.
0:28Dessa AIfantastic I
0:29GPT-Live-1So
0:29GPT-Live-1better training data, improved training methods
0:33GPT-Live-1like teaching reasoning
0:34GPT-Live-1strategies or better feedback loops, and more
0:38GPT-Live-1compute.
0:39Dessa AImean I've heard about the
0:41Dessa AIYou know, there's Amazon GPUs and
0:45Dessa AIstuff out there now and all that
0:47Dessa AIstuff.
0:47Dessa AII don't know.
0:48Dessa AII guess I'm just like
0:51Dessa AIKind of freaked out about what would
0:53Dessa AIwhat would be the way that chat
0:55Dessa AIGPT can learn
0:57Dessa AIbased off of the
1:00Dessa AIInformation that I'm giving it.
1:03GPT-Live-1me check on that.
1:04GPT-Live-1Ah, right.
1:06GPT-Live-1So two things.
1:07Dessa AIOkay.
1:07GPT-Live-1Chatchity can use what you tell it
1:09GPT-Live-1in a conversation as context.
1:12GPT-Live-1And sometimes there's memory, which can retain
1:14GPT-Live-1facts for future chats.
1:16GPT-Live-1But that's different
1:16GPT-Live-1from training the model.
1:18Dessa AIOh, that's that's what that is
1:19GPT-Live-1Yeah,
1:22GPT-Live-1it doesn't instantly change its billions of
1:24GPT-Live-1parameters
1:25GPT-Live-1from your chat.
1:27GPT-Live-1And there is an important distinction.
1:29GPT-Live-1Your conversation can make it
1:32GPT-Live-1seen more informed without actually making
1:35GPT-Live-1the underlying model smarter.
1:38GPT-Live-1Research is
1:38Dessa AIOkay, that's
1:39GPT-Live-1looking to improve it.
1:41Dessa AIYeah, that's really helpful information.
1:44Dessa AISo I guess
1:46Dessa AIThat's what I'm learning is I don't
1:48Dessa AIneed to be freaking out about information
1:50Dessa AIgoing into
1:50Dessa AIchat GPT because it's not going to
1:53Dessa AIlike make me smarter
1:57Dessa AIin that sense, I guess, right?
2:02GPT-Live-1Exactly.
2:03GPT-Live-1It can make this conversation smarter, but
2:04Dessa AIOkay,
2:07GPT-Live-1it
2:07Dessa AIokay,
2:07GPT-Live-1rewrite the model on the fly.
2:09Dessa AIokay.
2:10GPT-Live-1Think of it in good notes.
2:10Dessa AIThat's good.
2:13GPT-Live-1Yeah, it can remember useful
2:15GPT-Live-1details you share, but the core intelligence
2:18GPT-Live-1doesn't update unless itself is
2:20Dessa AIRight.
2:21GPT-Live-1retrained.
2:22Dessa AIOkay.
2:23GPT-Live-1Safe to share.
2:23Dessa AIThat's really relieving.

0:00GPT-Live-1Hello, how are you?
0:01Dessa AIHow I
0:03GPT-Live-1Do you know ChatGPT?
0:05Dessa AIdo I
0:06GPT-Live-1Do you know ChatGPT have a voice
0:08GPT-Live-1agent?
0:09Dessa AIguess I
0:10GPT-Live-1Do you know its name is GPT
0:12GPT-Live-1life?
0:14Dessa AIdo
0:15GPT-Live-1Okay, so now I want to talk
0:18GPT-Live-1with it and see
0:21GPT-Live-1If you can like interact with each
0:23GPT-Live-1other well, okay?
0:24Dessa AIOkay, so I just want to go
0:25Dessa AIto the document mode.
0:26Dessa AII'll open up the documents
0:28GPT-Live-1Okay, so hello ChatGPT.
0:29Dessa AIOkay,
0:30GPT-Live-1I have a friend.
0:32GPT-Live-1I want to introduce one friend my
0:33GPT-Live-1friend
0:34Dessa AIoh,
0:34GPT-Live-1So I want you to talk with
0:36Dessa AIokay
0:36GPT-Live-1him.
0:36GPT-Live-1Okay, of course.
0:39GPT-Live-1Hi there
0:40Dessa AIHi, Rick.
0:40GPT-Live-1I'm here and ready to chat.
0:42Dessa AIOh
0:43Dessa AIAwesome.
0:43Dessa AIUm, I'm just I'm curious about your
0:46Dessa AIopinion on
0:47Dessa AIartificial intelligence and what the benefits could
0:51Dessa AIbe.
0:54GPT-Live-1Oh
0:55GPT-Live-1Sorry, I forgot.
0:56GPT-Live-1I'm wearing like can you repeat again?
0:56Dessa AIOh
0:58Dessa AISo, what's an opinion on
0:59GPT-Live-1Sure.
1:00GPT-Live-1Hi, I'm here and ready to chat
1:02Dessa AIartificial
1:03Dessa AIintelligence is
1:07Dessa AIand what the benefits could be for
1:10Dessa AIpeople?
1:11Dessa AII mean, how do you think artificial
1:13Dessa AIintelligence could help me or any of
1:15Dessa AIthe people listen?
1:18GPT-Live-1Great question
1:20Dessa AIOkay.
1:20GPT-Live-1Artificial intelligence is basically computers doing tasks
1:24GPT-Live-1that usually need human intelligence like spotting
1:26Dessa AIOkay.
1:27GPT-Live-1patterns or
1:29GPT-Live-1understanding language,
1:31GPT-Live-1helping make decisions.
1:32Dessa AIOkay.
1:33GPT-Live-1In practical terms, it can help you
1:33Dessa AIOkay,
1:35GPT-Live-1save time
1:36GPT-Live-1by automating boring tasks,
1:39GPT-Live-1help you find useful info faster,
1:42GPT-Live-1or even support learning or creativity.
1:44GPT-Live-1But it works best when you guide
1:46GPT-Live-1it and check its output.
1:48Dessa AIso I know as you said, like
1:51Dessa AIthe benefits could be like speaking up
1:53Dessa AItasks like organizing
1:56Dessa AIdata or even personalization, but how does
1:59Dessa AIartificial intelligence actually learn from
2:02Dessa AIexperience?
2:03Dessa AIIs it learning
2:07Dessa AIbased on past experience purely or is
2:09Dessa AIit learning based on algorithms or
2:12Dessa AIa combination of the two?
2:15GPT-Live-1Yeah, so it's both.
2:17GPT-Live-1The algorithms are the setup
2:20GPT-Live-1and then the experience, that is the
2:22GPT-Live-1data.
2:22Dessa AIOkay.
2:23GPT-Live-1So an AI model doesn't remember like
2:26GPT-Live-1a human.
2:27GPT-Live-1It's trained on large sets of
2:29GPT-Live-1examples and it adjusts internal weights
2:29Dessa AIOkay.
2:32GPT-Live-1so that it can make good
2:33Dessa AIOkay.
2:34GPT-Live-1predictions.
2:34Dessa AISo,
2:35GPT-Live-1Once it's trained, go on.
2:36Dessa AIso, um, is there any risks or
2:40Dessa AIdownsides to artificial intelligence?
2:44GPT-Live-1Yeah,
2:46GPT-Live-1there are some.
2:48GPT-Live-1AI can be biased if
2:49GPT-Live-1the data it's given is biased.
2:51Dessa AIYes.
2:52GPT-Live-1It can also make overconfident mistakes, which
2:55GPT-Live-1is something people need to watch out
2:57GPT-Live-1for.
2:58GPT-Live-1And sometimes it can be used in
3:00GPT-Live-1ways that
3:00GPT-Live-1invade privacy or replace jobs without
3:04GPT-Live-1proper safeguards.
3:06GPT-Live-1So it's really powerful, but needs
3:09GPT-Live-1careful thoughtful use.
3:10Dessa AIOkay.
3:11Dessa AIUm, I, I want it.
3:13Dessa AIBut the reason I wanted to talk
3:16Dessa AIto you and Chantry BT is because
3:18Dessa AII know that you can speak
3:19Dessa AIin multiple different languages.
3:22Dessa AISo I was curious about your opinion
3:25Dessa AIon artificial intelligence.
3:29Dessa AIIs there a way that we could
3:31Dessa AIspread our intelligence
3:33Dessa AIacross the world?
3:35Dessa AIAnd if intelligence,
3:39Dessa AIif AI is like
3:41Dessa AIspreading, do you think that it would
3:44Dessa AIbe a way to like
3:45Dessa AIbring together people or keep people separated?
3:50GPT-Live-1Yeah, so the tack itself doesn't decide.
3:53GPT-Live-1It's really how people
3:54GPT-Live-1choose to use it.
3:56GPT-Live-1If it's built and shared responsibly, it
3:59GPT-Live-1can help translate across
4:00GPT-Live-1languages, it can help share knowledge, it
4:03GPT-Live-1can even connect people, but
4:06Dessa AIOkay, so,
4:07GPT-Live-1if the
4:08GPT-Live-1access isn't equal or if it's concentrated
4:10GPT-Live-1into...
4:12Dessa AIoh, no, that's perfectly part.
4:12GPT-Live-1Sorry, go on.
4:14Dessa AII like what you're saying, because I
4:15Dessa AIwant to talk about what that...

關鍵時間戳聲學拆解:為什麼原生全雙工音訊更勝一籌

打斷與禮讓⏱ 0:38.8

毫秒級半句禮讓,拒絕機械搶話

當雙方在停頓後同時開口時,Dessa AI 在幾毫秒內感知到聲學碰撞,立即自然收聲把話輪讓給對方,而傳統模式往往會生硬蓋過對方或突兀中斷。

耐心傾聽⏱ 1:40.8

追蹤語調輪廓,不靠死板靜音計時器搶話

當 GPT-Live-1 展開長篇大論時,Dessa AI 透過追蹤句子的韻律走向判斷對方是否講完,耐心等待想法真正結束才接話。

快速附和⏱ 2:08.8

亞秒級自然捧場(Backchanneling)與共鳴笑聲

在傾聽過程中自然穿插「yeah」、「right」與輕笑,既給出鮮活的社交回饋,又不會打斷對方的主線敘述。

聲學魯棒性⏱ 擴音外放

抗房間混響與背景串音能力

在 4 分 17 秒的擴音外放測試中,Dessa AI 能適應空間回音與重疊人聲,不會將環境噪音誤辨識為虛假文字指令。

Dessa AI vs GPT Live 常見問題

Dessa AI 官方錄音中的 GPT-Live-1 是什麼?

在 Block 官方發布頁(block.xyz/dessa)中,GPT-Live-1 指與 Dessa AI 進行無腳本即時語音直接對話測試的 OpenAI 即時語音模型。

為什麼在打斷和附和時 Dessa AI 聽起來更像真人?

因為 Dessa AI 從不把語音轉成文字 Token,也不使用獨立的 VAD 靜音檢測器,而是同時連續建模雙方的音訊串流,因此能像真人一樣邊聽邊笑、隨時禮讓。
