UnverifiedThe time-to-first-byte for cloud TTS services is typically 200–500 milliseconds, making it the primary source of latency bottlenecks.80% similarUnverifiedA Time to First Token (TTFT) below 500ms is generally considered a smooth interactive experience, while exceeding 2 seconds creates a noticeable sense of waiting.76% similarUnverifiedNatural pauses in human conversation typically range from 200 to 500 milliseconds, and if TTS TTFB exceeds this threshold, users will noticeably perceive unnatural latency.76% 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.76% similarUnverifiedGear backlash is typically only a fraction of a degree, and control latency is typically on the order of 5–20 milliseconds.75% similar
