Grammar Format Specification

Print-friendly Version

Version 1.0 - October 26, 1998

The Java Speech Grammar Format is a platform-independent, vendor-independent textual representation of grammars for use in speech recognition. Grammars are used by speech recognizers to determine what the recognizer should listen for, and so describe the utterances a user may say. JSGF adopts the style and conventions of the Java programming language in addition to use of traditional grammar notations.
