UnverifiedTime to First Audio (TTFA) refers to the time elapsed from text input to the output of the first frame of playable audio, and is a core metric for measuring the response speed of streaming TTS systems.78% similarUnverified端侧TTS需在用户说完后200-500ms内开始语音反馈才能保持对话流畅感，要求模型以流式方式逐帧生成音频75% similarUnverifiedTTS must stream tokens into speech one by one and cannot wait until the entire response is generated before converting to speech, in order to reduce latency.74% similarUnverified语音AI系统中的中断处理需要在毫秒级别内完成停止TTS音频流、丢弃未播放内容、重置LLM上下文状态、重新进入STT监听模式等操作74% similarVerifiedModern voice cloning solutions typically use a speaker encoder to map a voice into a high-dimensional embedding vector, which is then injected into the acoustic model during the TTS decoding stage to control the output timbre.72% similar
