Gemini stopped generating Russian TTS voice

Hello,

Since September 17, 2025, I have been experiencing an issue with Gemini in AI Studio when trying to generate audio from Russian text.

  • Before that date, everything worked fine: Gemini could generate Russian text-to-speech without problems.
  • However, in the middle of a session it suddenly stopped generating any Russian voice output.
  • From that moment on, Gemini does not generate any audio for Russian text at all (no sound, or “No Audio Generated” message).
  • English text still works perfectly fine — only Russian TTS is broken.

I tested:

  • Different browsers (Chrome, Firefox, Incognito mode)
  • Different lengths of text (short phrases and longer sentences)
  • My internet connection and account settings

The result is always the same: English → voice works, Russian → no audio.

Could you please confirm if this is a temporary issue or if Russian voice support has been disabled?
Any guidance or ETA for a fix would be greatly appreciated.

Thank you!

Hi @Petr_Ovsanik
I was able to successfully generate speech from Russian text in Chrome. It may have been a temporary issue, but I’d appreciate it if you could verify it once more. If the problem persists, please provide an error message or a screenshot.
