This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The interpretation read-only property of the SpeechRecognitionEvent interface returns the semantic meaning of what the user said.
This might be determined, for instance, through the SISR specification of semantics in a grammar (see Semantic Interpretation for Speech Recognition (SISR) Version 1.0 for specification and examples.)
Syntax
var myInterpretation = event.interpretation;
Value
The returned value can be of any type. If no semantic interpretation has been returned by the speec recognition system, null will be returned.
Examples
recognition.onresult = function(event) {
var color = event.results[0][0].transcript;
diagnostic.textContent = 'Result received: ' + color + '.';
bg.style.backgroundColor = color;
console.log(event.interpretation);
}

Firefox OS permissions
To use speech recognition in an app, you need to specify the following permissions in your manifest:
"permissions": {
"audio-capture" : {
"description" : "Audio capture"
},
"speech-recognition" : {
"description" : "Speech recognition"
}
}
You also need a privileged app, so you need to include this as well:
"type": "privileged"
