    > LLMs need an insane amount of text. Dessa learned language from hundreds of times fewer words (in fairness, LLMs also have to learn C++ and whatever the hell Angular is).

    Now that a larger proportion of text is AI, I'm appreciating human-written text more and more; this got a good chuckle out of me.

    This feels like a parlor trick where the AI was trained to mimic informal telephone mannerisms. The actual conversations were pretty bad. Lots of style, not much substance basically.

    These bidi/duplex demos always come off as overly artificial to me. It's cool that the model can speak at the same time as you instead of taking turns, but training it to interrupt as much as possible isn't the way to do it. In the very first example, did anyone here find the laugh after the "winter" answer to be convincing? What was the need for it? Why did the human speaker not get to finish a single sentence or finish a thought before the model took over with a monologue?

      I get irrationally angry when actual people interrupt me while I'm talking, I'll start throwing chairs when AI tech support agents start doing it.

      I'm absolutely going to hate talking to these things as customer service agents, with fake vocal fry and odd amounts of intonation and emotion peppered in.

      For sure there's gonna be people falling in love with them though! I find all the anthropomorphization creepy though.

    I actually thought it sounds really good and natural and it freaked me out in a good way. You can tell that the robots have no idea of what they're talking about, but the voicing, the emotions, etc, really good.. Like talking to a friend on the phone. Also creepy, because of the potential for abuse of this technology.

    But the interesting part to me is that training on voice only is what allows models to learn emotions - voice transmits a lot of emotional information which text doesn't capture. Language has words for a very limited number of emotions - maybe only the peaks - but there's so many more which we can't describe or transmit via text.

    You could determine the phonetic tokens which express different kinds of emotions or 'render' text+emotion using a DSL, etc. Exciting stuff.

    Interesting tech, but if these are the hand-picked examples that best represent it, I suppose we're not quite there yet.

    The intelligence sounds lacking. At this point, anyway.

    But the idea of learning through voice instead of written text might prove fruitful. After all, text isn't strictly native to humans. It's just a tool we've invented.

    These full-duplex models are getting very "Her"-ish lately. gpt-live-1 is fantastic. Dessa, though, seems to be aiming at full human parity. There's a huge market for AI girlfriends that they should be looking into in earnest...

    > we figured out how to train Dessa on only one NVIDIA GB200 NVL72.

    This is the crazy part. It seems pretty smart, and LLMs require 1000x more compute to train. Can this kind of efficiency somehow be achieved with text too?

  • bityard 20 minutes ago
    Not bad, but I guess I lack the imagination to envision the use cases for such casual conversation. Other than... I suppose a certain demographic would be lining up to use this as the voice for their AI girlfriend.

    Also I seem to be missing where/how they are selling this.

    Both speakers in the examples sound unnatural. The human doesn't know what to talk about and seems to have little confidence. The robot says things that only mostly make sense and draws on, saying ultimately very little. "How's the winter stuff?" e.g. is not a sentence a person would say. I might say "How are you dealing with the snow?" or "Are you looking forward to winter?," but not "How's the winter stuff?" And there's just so many examples like this. Also, I'm not convinced that this "human-like" conversation with filler words and interruptions and pauses is actually what anyone wants, especially in absence of a face to interpret or a real human being to understand behind it. Even if it worked perfectly, it would feel uncanny and artificial because I know the person isn't real.

      They sound just as unnatural als the annoying actors in the 'Gilmore Girls' series my daughter keeps on watching and re-watching, i.e. stupid valley girl or whatever it is called witless drivel. In that sense this model is tailor-made to create direct script-to-screen voice-overs for pabulum like that.

    Can you instruction-train a duplex model like this? How would that look? I also wonder, if a model trained only on speech can develop world knowledge like this, could you train an image model only on images of text to essentially act as an LLM?
  • haarts 17 minutes ago
    Ok. Sounds cool. Now what? Open source weights? An API somewhere? Available on Openrouter? Are they just testing?

    Where is this going?

    Now that a robot can speak over people on Zoom calls for me, I’m finally free to write poems all day!

    I'm surprised it took this long! Clearly the next step is joint training on text and audio. The speech realism is very good, but the intelligence is pretty clearly 2024-level.

    not at all creepy
  • actualwitch 42 minutes ago
    The speech is great, but you can see some cracks even in the first sound bit. near the end he asks the model to speak louder and initially the voice is louder but then goes back to the same level, also losing what she was saying just seconds ago and he has to lead back to the topic.

    crazy, if true!

    Sorry I'm lost. The sample on the homepage sounds absolutely awful. Not one bit of the cadence individually and together, the tonal ranges in responses or the overall structure and feel is comfortable to listen to, it's so far off passing as 'real' that I feel like I must be missing something.
    • superchicken099 1 hour ago
      Sure it definitely had some strange moment but it’s impressive for a small training data set and low compute
      • kennywinker 1 hour ago
        That doesn't sound like the same bar as "most authentic full-duplex speech model ever built"
    • VulgarExigency 53 minutes ago
      I think it sounds slightly "off" but its cadence certainly sounds way more like a human than other AI voices I've heard.

      Have you tried the alternatives? This is clearly far far superior in terms of fluidity of conversation.
