object instance.

Examples
In our simple Speech color changer example, we create a new SpeechRecognition
object instance using the SpeechRecognition()
constructor, create a new SpeechGrammarList
, add our grammar string to it using the SpeechGrammarList.addFromString
method, and set it to be the grammar that will be recognised by the SpeechRecognition
instance using the SpeechRecognition.grammars
property.
var grammar = '#JSGF V1.0; grammar colors; public <color> = aqua | azure | beige | bisque | black | blue | brown | chocolate | coral | crimson | cyan | fuchsia | ghostwhite | gold | goldenrod | gray | green | indigo | ivory | khaki | lavender | lime | linen | magenta | maroon | moccasin | navy | olive | orange | orchid | peru | pink | plum | purple | red | salmon | sienna | silver | snow | tan | teal | thistle | tomato | turquoise | violet | white | yellow ;' var recognition = new SpeechRecognition(); var speechRecognitionList = new SpeechGrammarList(); speechRecognitionList.addFromString(grammar, 1); recognition.grammars = speechRecognitionList;
