and provide the requested information:

Name

The name of the file, without the extension (it is provided automatically).

Source folder

The folder that contains the newly created grammar file.

Root Rule Name

The name of the grammar's root rule. If not specified, it defaults to the name of the file.

Language

The default language for the words in the grammar. Language identifiers are of the form cc-CC or cc where c is a letter. For example: en, fr, fr-CA, us-UK.

• semantics/1.0, as defined by the SISR specification,
• semantics/1.0-literals, also defined by the SISR specification,
• semantics/1.0.2006, the LumenVox name for semantics/1.0,
• semantics/1.0.2006-literals, the LumenVox name for semantics/1.0-literal,
• semantics-ms/1.0, for the semantic language supported by Microsoft Speech Server,
• swi-semantics/1.0 for Nuance OSR, and,
• Nuance for the semantic language of Nuance's GSL grammars.
