We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.

this is big (but also really really small…small enough to run on your macbook).

i’m extremely proud of the dessa team for pushing the frontier! ❤️

@jack Explain why we need natural voice synthesis. Explain why a computer should be able to pass as human and why that's a good thing for society. Tech bros are a blight on humanity.

@jack Robots or AI have no reason or practical utility for sounding and behaving like humans.

The only result is deception, so the question is: who are you trying to deceive?

If my toaster is speaking to me, I want to know it's a toaster, nothing else.

@jack Why do people think everyone wants ‘natural’ and ‘authentic’ voice models? I want one that gets straight to the point without unnecessary interjections and pauses. Lmfao.

@jack okay the examples are insanely good... but at the same time very dystopian..

can't think of a good use case for this not involving AI psychosis.

again, insanely good models, but I would rather have my AI talk like Jarvis and not a real person..
