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.
