SpeechGrammar.src

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The src property of the SpeechGrammar interface sets and returns a string containing the grammar from within in the SpeechGrammar object.

Syntax

var myGrammar = speechGrammarInstance.src;

Value

A DOMString representing the grammar.

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;


console.log(speechRecognitionList[0].src); // should return the same as the contents of the grammar variable
console.log(speechRecognitionList[0].weight); // should return 1 - the same as the weight set in line 4.

1. Note that currently only the speech synthesis part is available in Firefox Desktop — the speech recognition part will be available soon, once the required internal permissions are sorted out.

2. From version 44: this feature is behind the media.webspeech.recognition.enable preference (needs to be set to true). To change preferences in Firefox, visit about:config.
