Jack Dorsey's Block releases Dessa, a human-like speech model

By PulseAugur Editorial · [1 sources] ·

Block, a company founded by Jack Dorsey, has unveiled Dessa, a novel full-duplex speech model. This model is unique in that it was trained exclusively on human speech using a single Nvidia GPU and can operate locally on consumer hardware. Dessa differentiates itself by integrating emotional nuance directly into the voice synthesis, rather than relying on external tags. While not yet publicly available, Block is seeking safety researchers to evaluate its potential for deceptive use. AI

IMPACT This model's ability to run on consumer hardware and integrate emotional nuance directly into speech could lead to more natural and accessible AI voice interactions.
