MetaVoice text-to-speech models & pricing

Latency from public benchmarks

Time to first audio, in milliseconds, as each benchmark publishes it. We don't measure latency ourselves, and the sources measure differently (harness, region, sample size), so each figure stays under its own source. Not part of the composite score.

None of the latency benchmarks we read lists a MetaVoice model yet.
