Language Support

The Cloud Natural Language API supports a variety of languages. These languages are specified within a request using the optional language parameter. Language code parameters conform to ISO-639-1 or BCP-47 identifiers. If you do not specify a language parameter, then the language for the request is auto-detected by the Natural Language API.

The list of supported languages differs depending on the feature.
