# Supported Languages

Which languages you can transcribe, translate, and analyze, with the full lists shown in the app's dropdowns.

This page gives an overview of the languages you can transcribe, translate, and analyze in. The exact lists live in the app's dropdowns.

Last verified against the staging app on 14 October 2026.

## Transcription languages

* Choose your recording's language from the **Language of Audio** list, grouped by accuracy: **Best Accuracy**, **Better Accuracy**, and **Good Accuracy**. Many languages come in regional variants, such as **US English**, **British English**, and **Australian English**.
* "2 or more languages in 1 audio (auto-detect)", at the top of the list, handles recordings that switch language. It cannot be combined with a translation.
* Best and Better Accuracy languages support every option: role and name identification, the accuracy lists, AI analysis, and redaction. Good Accuracy languages lock some of them, with a note such as "Not available for …", and suggest a better entry when one exists.
* The full list loads inside the app; type in the search box to find yours.

**Tip:** Picking the most specific language or accent improves accuracy a lot. Add names and jargon under **Custom Dictionary**. See [Transcribe Audio & Video](/ailyze-docs/prepare-research-data/transcribe-audio-and-video.md).

## Translation languages

* Pick your **Origin** (source) and **Destination** (target) languages in the translation setup.
* The full list loads inside the app. Which target languages you can choose can depend on your file format: some formats (`docx`, `pptx`, `xlsx`, `html`, `txt`) support every language, while others (`pdf`, `xliff`, `srt`) support only the higher-accuracy set. See [Supported File Types](/ailyze-docs/reference/supported-file-types.md).

## Analysis response language (documents and spreadsheets)

In document analysis, **Report in** (under the report options of the table builder) sets the language of the report. In spreadsheet analysis, **Optional Settings → "Specify your preferred language of response:"** offers **100+ languages**. Either way this sets the language of the **report** ([themes](/ailyze-docs/reference/glossary.md#theme), summaries, insights), separately from your data's language — so you can analyze data in one language and read the findings in another.

* Quotes are usually kept in their **original** language for accuracy.
* The default is **English**.

## Multilingual interview projects and survey building

* **Create AI Avatar Interviewer + Survey** and **Create Survey** let you build in several languages, and can **auto-translate** survey content between the languages you add.

## Choosing a multilingual approach

| Situation                                    | Approach                                                                         |
| -------------------------------------------- | -------------------------------------------------------------------------------- |
| Report in language X from data in language Y | Set **Report in** (documents) or the response language (spreadsheets)            |
| Unify mixed-language data before coding      | **Translate first**, then analyze                                                |
| Non-English audio                            | **Transcribe** (pick the language, or auto-detect for mixed audio), then analyze |
