English(EN) I Cut Voice AI Latency From 4.2s to 780ms with Deepgram + ElevenLabs

语音AI延迟从4.2秒大幅缩减至780毫秒，通过流式传输和缓存

作者 PulseAugur 编辑部 · [1 个来源] ·

一位开发者通过优化系统的各个组件，将语音AI延迟从4秒多显著降低到1秒以内。主要改进包括：将LLM响应的第一句话直接流式传输到文本转语音（TTS）引擎，为一致的系统提示实施提示缓存，以及通过自适应端点检测优化轮次检测。这些在Preterview平台上实现的更改，通过最小化可感知的延迟，极大地改善了用户体验。 AI
