# DialNexa Supported Languages Reference

> Understand DialNexa supported languages, language codes, language selection, Hinglish behavior, voice compatibility, and transcriber compatibility.

DialNexa supported languages are selected on an agent version and should be reviewed with voice and transcriber compatibility. A language record has a name and code, and some language choices can expose language-specific settings such as Hinglish Map.

<Tip>
  Language selection is the top of the stack, not the whole stack.

| Multilingual             | `mul`   | Lets the agent follow the caller across languages instead of locking to one.                                                                                |

<Note>
  Availability per agent depends on the selected voice, voice model, and transcriber - not every provider supports every language. The dashboard selectors only offer compatible combinations; see [Languages, Voices, Models, And Transcribers](/agents/languages-voices-models-and-transcribers).

## Language Data

Language records are simple but important.

| Field                     | Meaning                                                                     |

| code                      | Unique language code used by the system.                                    |
| voice compatibility       | Voices can support specific language ids.                                   |
| voice model compatibility | Voice models can be tied to supported languages.                            |
| transcriber compatibility | Transcribers should be tested with the selected language and caller accent. |
