Block发布Dessa语音模型
AI 总结
Block推出实验性全双工语音到语音模型Dessa，完全从人类语音训练，不使用文本数据。Block称该模型可同时听与说，识别笑声、停顿和讽刺等信息，并能在MacBook Pro M4 Max或更高配置设备上本地运行；模型尚未公开，Block计划先向少数AI安全研究者开放早期访问。
深度见解
Dessa提供了不同于先转写文本再生成回答的语音交互路线，但其演示、情绪理解能力和硬件表现尚无独立评测。

Block, the company behind Square and Cash App, has unveiled an AI speech model called Dessa.
Block says Dessa is the first AI model trained entirely on human speech, with no text data at all, built from scratch. Instead of converting audio to text first, Dessa processes speech directly as audio. That lets it pick up on emotions, sarcasm, laughter, and pauses in real time.
