OpenAI推出全双工语音模型GPT-Live-1，采用单一模型架构取代传统“语音转文字—推理—文字转语音”级联流程，显著降低延迟，实现类人流畅交互。该模型已上线API，面向开发者，能更稳健应对停顿、打断和话题转换等复杂对话场景。
OpenAI宣布将GPT-Live-1引入API，开发者可打造实时语音交互应用。该模型支持全双工对话，能同时听说，处理打断、停顿及背景噪声，适用于电话预订、客服等语音智能体；还可连接Codex等工具及OpenAI Presence，查询企业系统并执行获批操作。
OpenAI推出GPT-Live-1并开放API，支持全双工实时语音应用。该模型将语音理解与输出整合于同一架构，打破传统“语音转文字—大模型推理—文字转语音”的多段式流程，降低延迟与衔接壁垒，推动AI语音交互从分段处理向自然对话演进。
英伟达发布首款开源端到端全双工语音对话模型NemotronLabs VoiceChat11B，用单一网络直接完成流式语音理解与生成，取代传统ASR、LLM、TTS分步架构，实现实时语音交互突破。
LPM 1.0是17B参数模型，实时生成全双工AI视频，低延迟身份一致。
