The AppendRuleReference methods can append a grammar file or a grammar rule from a file. These methods allow applications to make use of pre-deployed or publicly available grammar rules. The application must have read access to the location of specified grammar files.
These methods can read a speech recognition grammar from the following formats.
-
XML-format files that conform to the W3C Speech Recognition Grammar Specification (SRGS) Version 1.0
-
Binary files that conform to the Microsoft Speech Recognition Grammar Binary Format (.cfg file extension)
Compiling an XML-format SRGS grammar file to a binary grammar file with the .cfg extension can reduce the time consumed by searches for a match, especially if the grammar requires recognition of a large number of words and phrases. For information about compiling SRGS grammars to the CFG binary format, see SrgsGrammarCompiler.
