Language tested
36 text-to-speech (TTS) models, ordered speed first: by speed tier and P95 time to first audio on Coval, then the models Coval does not measure, by name. No combined score.
Data checked on October 22, 2026 · updated after each benchmark capture
36 of the 119 text-to-speech (TTS) models in this benchmark were tested in French by Artificial Analysis (controlled-voice arena) or Speko (multilingual board). A model missing from this page was not tested in French: that does not mean it cannot speak French.
A model is listed here only when an independent benchmark measured its output in French. The list is ordered speed first, on Coval's English latency measurements: no public source measures latency in French. The model pages give every measurement and its date.
