Language support

Document AI API's text recognition feature (OCR) is able to detect a wide variety of languages and can detect multiple languages within a single document.

Languages detected by the Document AI API are returned in the Document object in the detectedLanguages field.

Each language code parameter typically consists of a BCP-47 identifier. This parameter can be of the form language-region, where language refers to the primary language and the optional region refers to a region (usually a country identifier) of a particular dialect. For example, Chinese can be represented as Simplified Chinese as written in the People's Republic of China (zh-Hans) or Traditional Chinese as written in Taiwan (zh-Hant).

Document OCR processor language support

Currently, English is the only language supported for Document OCR functionality.

There are three levels of language support in OCR functionality:

Supported languages are those we prioritize and regularly evaluate performance against.
Experimental languages are those under active development but not regularly evaluated against.
Mapped languages are those supported by mapping them to another language code or to a general character recognizer. For example, "en-GB" is supported, but it is not treated any differently than "en" for the purposes of recognizing text. We make a best-effort to return the correct mapped language code in the Entity locale field, but mapped languages are more likely than fully supported or experimentally supported languages to be misidentified as a similar language.
