Some providers use different models for specific languages:

| Provider   | Language | Model   |
| ---------- | -------- | ------- |
| **Google** | Sindhi   | chirp-2 |

<Note>
  Google STT uses `chirp-2` model for Sindhi, instead of the default `chirp-3`.
  This is handled automatically by Calibrate.
</Note>

<Note>
  Gemini has no dedicated STT endpoint. Transcription runs through the Gemini
  multimodal model (`gemini-3.5-flash`) using the Gemini API.
