UnverifiedThe time-to-first-byte for cloud TTS services is typically 200–500 milliseconds, making it the primary source of latency bottlenecks.74% similarUnverified流式架构可将端到端首字节延迟(TTFA)从串行叠加的1-3秒压缩至300-500ms量级73% 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72% similarUnverified访问主内存的延迟高达200-300个时钟周期71% 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.71% similar
