Block’s new voice model sounds eerily human

Block released Dessa, a full-duplex speech-to-speech model trained entirely on human speech that runs locally on a single NVIDIA GPU or consumer hardware such as a MacBook M4 Max. The company says emotion is built into the model rather than driven by text or voice tags, and it has called for safety researchers to test Dessa, which is not publicly available.

Block's new AI model Dessa was trained entirely on human speech to catch emotions text-based models miss

Block, the company behind Square and Cash App, has unveiled Dessa, an AI speech model it says is the first trained entirely on human speech with no text data, built from scratch. Dessa processes speech directly as audio rather than converting it to text first, letting it pick up on emotions, sarcasm, laughter and pauses in real time, and it supports full-duplex communication so it can listen and talk at the same time. It runs locally on a MacBook Pro M4 Max, was trained on a single NVIDIA GB200 NVL72, and is not yet publicly available, with the team first seeking AI security researchers to test it for unexpected risks.
