Check the Browser compatibility table carefully before using this in production.
The SpeechGrammar interface of the Web Speech API represents a set of words or patterns of words that we want the recognition service to recognize.
Grammar is defined using JSpeech Grammar Format (JSGF.) Other formats may also be supported in the future.
