Language - Amazon Lex

The following discussion applies to language identifiers applied to grammars. For more information, see Language in the Speech recognition grammar specification version 1 W3C recommendation.

By default a grammar is a single language document with a language identifier provided in the language declaration in the grammar header. All tokens within that grammar, unless otherwise declared, will be handled according to the grammar's language. Grammar-level language declarations are not supported.

In the following example:

The grammar header declaration for the language "en-US" is supported by Amazon Lex V2.
Item-level language attachment (highlighted in red) is not supported. Amazon Lex V2 throws a validation error if a language attachment is different from the header declaration.
