This API is available on Firefox OS for internal applications only.


The onvoicechange property specifies an event listener to receive voicechange events. These events occur whenever the MozMobileConnection.voice connection object changes.

Note: MozMobileConnection inherits from the EventTarget interface, so it's also possible to listen for events by using the addEventListener() method.


navigator.mozMobileConnection.onvoicechange = funcRef;

Where funcRef is a function to be called when the voicechange event occurs.


Not part of any specification.
