Artificial Analysis finds no single open-weight text-to-speech model ahead on all nine new language leaderboards. Leadership is split among Higgs Audio V3 TTS, OpenAudio S1 Mini, Voxtral TTS and Breeze TTS 2.
Artificial Analysis has extended the Controlled Voice Arena with separate text-to-speech leaderboards for Japanese, Mandarin Chinese, Hindi, Spanish, German, French, Portuguese, Vietnamese, and Arabic. Rankings use native-language prompts, standardized cloned voices, and preference votes from first-language speakers.
No single open-weight text-to-speech model leads all nine languages in Artificial Analysis’s rankings. Higgs Audio V3 TTS, OpenAudio S1 Mini, Voxtral TTS, and Breeze TTS 2 each top the open-weight field in different languages, and each board includes only 2 to 6 open-weight models.
