SpeechGrammar: SpeechGrammar() constructor
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The SpeechGrammar() constructor of the SpeechGrammar interface creates a new SpeechGrammar object instance.
