5 of the 112 text-to-speech (TTS) models in this benchmark were tested in Tamil by Artificial Analysis (controlled-voice arena) or Speko (multilingual board). A model missing from this page was not tested in Tamil: that does not mean it cannot speak Tamil.
A model is listed here only when an independent benchmark measured its output in Tamil. The ranking below is the overall benchmark score (latency, accuracy, voice quality and price), not a Tamil-only score; the model pages give the measurements and their dates.
