Abstract

A method of generating a speech recognition grammar for use with a speech recognition system can include parsing the corpus of data to identify grammatical structures within the corpus of data. The identified grammatical structures can be compared with grammar generation rules to determine particular ones of the identified grammatical structures to include within the speech recognition grammar. The grammar generation rules can designate which grammatical structures are to be included within the speech recognition grammar. The grammatical structures which have been identified in the parsing step and which also have been designated by the grammar generation rules can be included in the speech recognition grammar.
