Language reference

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


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.
