UnverifiedThe end-to-end latency of a real-time AI tutor is composed of three stacked segments: ASR latency (50–500ms), LLM first-token generation latency (100–2000ms), and TTS first audio frame latency (50–300ms).76% similarUnverifiedSTT、LLM、TTS三段串行叠加，仅处理延迟就超过650毫秒，不包括服务间网络跳转耗时75% similarUnverifiedThe time-to-first-byte for cloud TTS services is typically 200–500 milliseconds, making it the primary source of latency bottlenecks.75% similarUnverifiedCloud TTS services typically have a time-to-first-byte of 200–500 milliseconds, while locally deployed lightweight TTS models (such as Piper and Kokoro-82M) can reduce latency to under 50 milliseconds, though audio quality is generally slightly lower.74% similar
