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"
