The real-time API accepts ISO-639-1 language codes (`en`, `es`, `zh`, …).
Regional tags are accepted (`en-US`, `pt-BR`) — only the primary subtag
is used.

Pass `auto` as `sourceLanguage` to let Pinch detect the spoken
language; the detected code is returned on every transcript frame as
`detected_language`.

## Languages

Every code below is supported as both `sourceLanguage` (input speech)
and `targetLanguage` (output text). The **Voice output** column marks
which languages also have a synthesized voice — use these with
`audioOutputEnabled=true`. Languages without a voice are text-only and
must be requested with `audioOutputEnabled=false`.

| Code | Language | Voice output |
| --- | --- | --- |
| `ar` | Arabic | ✓ |
| `cs` | Czech | ✓ |
| `da` | Danish | ✓ |
| `de` | German | ✓ |
| `el` | Greek | ✓ |
| `en` | English | ✓ |
| `es` | Spanish | ✓ |

| `fr` | French | ✓ |
| `hi` | Hindi | ✓ |
| `hu` | Hungarian | ✓ |
| `id` | Indonesian | ✓ |
| `it` | Italian | ✓ |
| `ja` | Japanese | — |
| `ko` | Korean | — |
| `mk` | Macedonian | — |
| `ms` | Malay | — |
| `nl` | Dutch | ✓ |
| `pl` | Polish | ✓ |
| `pt` | Portuguese | ✓ |
| `ro` | Romanian | ✓ |
| `ru` | Russian | ✓ |
| `sv` | Swedish | ✓ |
| `th` | Thai | — |
| `tr` | Turkish | ✓ |
| `vi` | Vietnamese | ✓ |
| `yue` | Cantonese | — |
| `zh` | Chinese (Mandarin) | ✓ |

Every voice-output language ships with both a male and a female voice —
select via `voiceType` (`male` or `female`).

Requesting an unsupported `targetLanguage` with `audioOutputEnabled=true`
returns an `error` frame. Pass `audioOutputEnabled=false` to get
transcripts in any of the languages above.
