发生了什么: Perceived TTFA: the Coval TTS latency benchmark

Coval TTS benchmark now measures perceived latency including leading silence, exposing models that emit inaudible audio before speech starts.

为何重要: Perceived TTFA: the Coval TTS latency benchmark

Matters for engineers building voice applications where user-perceived responsiveness depends on when actual sound reaches the speaker.

注意: Perceived TTFA: the Coval TTS latency benchmark

Historical benchmark rows before this methodology change are not comparable; the metric shift revealed that some fast models felt slow due to silence padding.
