We use your devices native 'Text to Speech' (TTS) engine for voice instructions. If you don't hear anything, see the I can’t hear voice instructions article.
On Android devices, you can customise these settings with the ability to choose different voices, pitch and speed.
The exact instructions vary between devices and android versions. We recommend use of the Google TTS engine.
