 JSGF  |
Grammars are used by speech recognizers to determine what the recognizer should listen for, and so describe the utterances a user may say. JSGF a rule grammar (also known as a command and control grammar or regular grammar). A rule grammar specifies the types of utterances a user might say (a spoken utterance is similar to a written sentence). For example, a simple window control grammar might listen for "open a file", "close the window", and similar commands. What the user can say depends upon the context. It could be a grammar for reading a credit card number or for controlling email. Applications know the context, so applications are responsible for providing a speech recognizer with appropriate grammars. JSpeech uses a textual representation that is readable and editable by both developers and computers, and can be included in source code.
