Block's Voice AI Model Sounds Human
Block, formerly known as Square, has unveiled a voice AI model called Dessa that sounds remarkably human in company demonstrations. The model was trained on human speech and can handle interruptions, laughter, and changes in tone during a conversation. Block CEO Jack Dorsey wrote on X that conversations with Dessa feel like talking with a person, full of emotion, nuance, pauses, and a natural cadence. The model is currently a research preview and can run locally on a MacBook Pro with an M4 Max chip or better.
