Text-to-Speech (Gemini TTS) returning HTTP 500 – anyone else?

Gemini API

I’m seeing persistent HTTP 500 errors when calling the Gemini Text-to-Speech API and would like to know if others are affected.

Setup

  • Model: Gemini 2.5 Flash TTS

  • Voice: Charon

  • Request: Single-request synthesis, short text (~113 characters)

Error

  • Status: HTTP 500 Internal

Observed behavior

  • Retries with backoff (e.g. 2s, 4s, 8s) still get 500.

  • Same error across multiple attempts; transcription (e.g. generateContent) works, only TTS fails.

Is anyone else getting 500s on Text-to-Speech right now, or is this likely account/region-specific? Any known workaround or status page for TTS?

Thanks.
