Seems similar to that Moshi model from 6 months ago, but this is more refined than that, Moshi is a little crazy, but still it was an impressive demo of how low latency responses, continuous listening and interruptions can improve the voice chat and make it more real or uncanny, (sometimes its "latency" is even too low because is interrupts you before you finish)
