# Supported Languages

The langauges supported by the API are the same that are supported in our customer-facing application. They are:

* `en` — English (default)
* `de` — German
* `es` — Spanish
* `fr` — French
* `hi` — Hindi
* `id` — Indonesian
* `it` — Italian
* `ja` — Japanese
* `ko` — Korean
* `nl` — Dutch
* `no` — Norwegian
* `pl` — Polish
* `pt` — Portuguese
* `ru` — Russian
* `sv` — Swedish
* `tr` — Turkish
* `uk` — Ukrainian
* `zh` — Mandarin (Simplified)

Transcription supports auto-detecting audio language, however results will be higher quality if the correct language is specified.

**Note:** If the language code specified is different from the audio language (i.e. English was specified for an English podcast) the result will likely be much poorer than if auto detection was used.

**Note:** At the moment, the best way to handle multi-lingual audio is to use auto detection.
