Receive turn-by-turn navigation in your own voice using Waze (Android only for now)4
Setting up the recording is actually very simple. Just head to the “Sound & voice” settings, go to Voice Recorder, and repeat the list of preset phrases. That's all there is to it. Keep in mind that any directions that you don't record will default to the usual Waze voice.
This feature is only available on the Android version of the app for the moment, with no word on when it will be made available to iOS users. If you ever fancied a career as a voice over artist or as a replacement for the Moviefone guy, you can record your own voice and tell yourself where to go.
Download Waze by clicking on the appropriate link (Android|iOS).
