Language Identifier
A language identifier is part of the grammar header that specifies the language to be used when performing decodes.
The format of the language identifier follows the convention set out by RFC 3066. The identifier is a language and country pair, such as "en-US" for United States English.
The following languages are supported. As new languages and dialects are added over time, refer to the Languages Available Overview article for the most current list — specifically the Grammar ASR column for languages supported when working with grammars.
The platform supports the following languages:
Language Code | Description |
da-DK | Danish acoustic model and dictionary |
de-CH | Swiss German acoustic model and dictionary |
de-DE | German acoustic model and dictionary |

Digits-only Grammars
A non-standard language type with a suffix of "-di" was previously used to indicate that a language included digits only. This functionality is now obsolete — the Speech Engine automatically determines when it should use a digits-only acoustic model. Any language identifier with a "-di" suffix will be ignored by the Engine.
