Soniox TTS Real-Time v2
Soniox TTS Real-Time v2 is a proprietary text-to-speech (TTS) API from Soniox, measured by three independent benchmarks: Artificial Analysis, Coval and Speko.
Language tested
35 text-to-speech (TTS) models, ranked from the highest benchmark score to the lowest, out of 100.
Data checked on September 30, 2026 · updated after each benchmark capture
35 of the 112 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 ranking below is the overall benchmark score (latency, accuracy, voice quality and price), not a French-only score; the model pages give the measurements and their dates.
