Prepare Grammar Command-Line Syntax

The command-line syntax for PrepareGrammar.exe has the following format.

PrepareGrammar /In <input file name> /Out <output file name> /RecoConfig <configuration file name>

The following table describes the command-line option names and values for Prepare Grammar.

Option Name

Description

/In

Required. The file name and extension of a compiled grammar file, for example "MyGrammar.cfg".

/Out

Required. The file name and extension of the prepared grammar file, for example "MyGrammar.cfgpp". Files of the CFGPP format are optimized for a specific instance of a speech engine.

/RecoConfig

Optional. The name of the configuration file to use for the speech recognition engine. If not specified, the tool will look for a default configuration file named “RecoConfig.xml” in the current working directory and in the directory that contains PrepareGrammar.exe. The tool will generate an error if you do not supply it with a configuration file.

/?

Optional. Displays a list of acceptable option/value pairs.

Note

  • Command-line options and values are not case-sensitive.

  • Command-line options can be preceded by a forward slash (0x002F), a dash (0x002d), an en dash (0x2013), an em dash (0x2014), or a horizontal bar (0x2015).

  • You can enter option/value pairs in any sequence.

Warning

If an existing file has the same name as the file name specified by the /Out option, it will be overwritten. The tool does not warn that a file will be overwritten.

You must either specify a recognition engine configuration file using the /RecoConfig option, or create a default configuration file named "RecoConfig.xml" either in the current directory (the directory for the command line) or in the directory that contains PrepareGrammar.exe. Use the configuration file to specify a speech recognition engine to use, to configure the parameters for connecting to it, and to configure its behavior. For more information, see Setting Up the Grammar Development Tools.
