Language reference

This page lists all languages supported by Dialogflow CX. For more information on using languages, see Multilingual agents.

Limitations

The following limitations apply:

  • System entity support differs for different languages. Check supported system entities for a specific language in the System entities reference.
  • Dialogflow uses Cloud Speech-to-Text for speech recognition. Not all of the STT supported languages also support models for phone calls. The Cloud Speech-to-Text language reference lists languages that support the "Enhanced phone call" and "Phone call" models.

Symbol Description
* Language tags follow the HTTP/1.1 specification, section 3.10.
† Dialogflow supports both Cyrillic and Latin alphabets for Serbian. However, STT only transcribes spoken Serbian into Latin. If your agent uses the Cyrillic alphabet for training phrases and entity entries, you should restrict the agent to text-only interactions.
