Realtime, emotional and natural sounding Conversational Speech Model

This is the best realtime, natural sounding voice chat with AI that I’ve ever heard. They say its going to be open source too. This would be incredible and gamechanging to have in Venice. You have to check it out!

  • Emotional intelligence: reading and responding to emotional contexts.

  • Conversational dynamics: natural timing, pauses, interruptions and emphasis.

  • Contextual awareness: adjusting tone and style to match the situation.

  • Consistent personality: maintaining a coherent, reliable and appropriate presence.

Really natural sounding, it sometimes mispronounces words, it grows in confidence over time, it has memory for 2 weeks, it responds immediately, has emotion.. Its better than chatGPT’s too.

Try the demo here:

is there any chance of this if it does go open source?
The devs do promise it’ll all be open source.

    THAT is INCREDIBLE!  I thought that I was speaking with a human being. You cannot tell the difference as a matter of fact, I know humans that don't sound that good definitely need the sesame.com. The conversation was as natural as anybody I could talk to on daily basis.
