# Languages

Speech-to-text supports the same languages on the [Prerecorded](/speech-to-text/prerecorded/), [Realtime](/speech-to-text/realtime/), and [Turns](/speech-to-text/turns/) APIs.

Pass the `language` query parameter whenever you know the language ahead of time - pinning the language produces better transcription quality than auto-detect. When omitted, the server auto-detects each utterance independently, which is less reliable for short utterances.

## Multiple languages

The `language` parameter also accepts a comma-separated list of codes (e.g. `language=nl,en`). The server then auto-detects each utterance independently, restricted to the listed languages. This is more reliable than unrestricted auto-detection, but pinning a single language gives the best quality.

| Code | Language   |
|------|------------|
| `de` | German     |
| `en` | English    |
| `es` | Spanish    |
| `fr` | French     |
| `fy` | Frisian    |
| `it` | Italian    |
| `nl` | Dutch      |
| `pl` | Polish     |
| `pt` | Portuguese |
| `sv` | Swedish    |
