Language support

The Translation API's recognition engine supports a wide variety of languages for the Phrase-Based Machine Translation (PBMT) and Neural Machine Translation (NMT) models. These languages are specified within a recognition request using language code parameters as noted on this page. Most language code parameters conform to ISO-639-1 identifiers, except where noted.

Phrase-Based Machine Translation Model

A complete list of language tags supported by the Phrase-Based Machine Translation (PBMT) model are shown in the following table. The PBMT model supports translations from any language in this list to any language in this list. The list will be updated as new languages are added to the Translation API's PBMT model.
