SpeechRecognition.onsoundend

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

The onsoundend property of the SpeechRecognition interface represents an event handler that will run when any sound — recognisable speech or not — has stopped being detected (when the soundend event fires.)

Syntax

mySpeechRecognition.onsoundend = function() { ... };

Examples

recognition.onsoundend = function() {
  console.log('Sound has stopped being received');
}

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"
