Block 发布 AI 语音模型 Dessa，完全基于人类语音训练
block 的新 ai 模型 dessa 完全基于人类语音训练，以捕捉基于文本的模型忽略的情感。 这可能会改变语音 ai 交互。
block, the company behind square and cash app, has unveiled an ai speech model called dessa. dessa was trained entirely on human speech, with no text data, and processes speech directly as audio. this allows it to pick up on emotions, sarcasm, laughter, and pauses in real time. the model supports full-duplex communication and runs locally on a macbook pro m4 max. block built dessa out of curiosity, a desire for better human-ai communication, and safety concerns.
