You can control many of the phone functions with your voice. You can call contacts from the address book, dictate messages and search the internet. Before you can use voice control, you need to select voice control settings.
Tap and hold the Home key.
If you've turned on automatic activation, you can say "Ok Google" to activate voice control.
Say, in your own words, what you would like your mobile phone to do, e.g.: OPEN [application], CALL [contact], SEARCH FOR [information]. It's not necessary to use a specific command for each function.
Say "What can you do?" to see more examples of voice control commands.
