Google is apparently adding music playback controls to its Google Now service, Digital Spy reported.

Android Police claims that some devices now enable users to control their music via vocal commands following a new update for the Siri rival.

Google Now is said to understand commands such as 'next song/track', 'play next song', 'stop music' and 'pause music' for some users.

The new feature is intended for use in situations where hands-free controls are necessary, such as behind the wheel of a vehicle.

Google rolled out a new version of its Search app last month, bringing 'OK Google' voice functionality to all Android tablets and smartphones.

It is yet to be confirmed whether the media playback controls will be released on a wide scale.
