Block 发布本地运行语音模型 Dessa，情感表达逼真
原标题：Block’s new voice model sounds eerily human
AI 摘要
Jack Dorsey 旗下 Block 的研究实验室发布了一款名为 Dessa 的语音模型，该模型可在本地运行，能发出笑声、停顿和哭泣等类人表达，并完全基于人类语音训练，仅需一块 NVIDIA GPU。Dessa 是全双工模型，可同时说话和聆听，情感内建于模型之中，而非依赖文本管线或语音标签驱动。目前 Dessa 尚未公开访问，Block 正招募安全研究人员进行测试，以评估语音代理可能欺骗他人的风险；该模型未来有望以更低成本支撑 Block 在金融和小企业业务中的语音应用。

Typically, speech models are paired with a large language model for knowle
