SpeechRecognition: grammars property

The grammars property of the SpeechRecognition interface returns and sets a collection of SpeechGrammar objects that represent the grammars that will be understood by the current SpeechRecognition.

Note: The concept of grammar has been removed from the Web Speech API. Related features remain in the specification and are still recognized by supporting browsers for backwards compatibility, but they have no effect on speech recognition services.

Value

A SpeechGrammarList containing the SpeechGrammar objects that represent the grammars used by your app.
