is false
.)
The default value for interimResults
is
false
.

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"
