Dessa: Block's conversation model trained only on speech, no text at all

block.xyz

Full-duplex, trained from scratch on human conversation audio - no text, no pretrained LLM. Claims it picks up emotion, pauses, natural cadence. Big open question: how efficiently does it learn facts compared to text models?

trained only on audio means it probably knows how to say 'umm' perfectly but not what year it is

this is the interesting direction imo. speech-to-text-to-speech pipelines throw away so much
