SpeechGrammar()

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.

Syntax

var mySpeechGrammar = new SpeechGrammar();

Parameters

None.

Examples

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;

var newGrammar = new SpeechGrammar();
newGrammar.src = '#JSGF V1.0; grammar names; public <name> = chris | kirsty | mike;'
speechRecognitionList[1] = newGrammar; // should add the new SpeechGrammar object to the list
