How do you answer or reject a call by voice on the Galaxy S III?

[BrittanyC]

Did not know this was a feature?

Hey Jacob!

If you go to Settings -> Language and Input -> Voice CMD for Apps -> Turn them on. If you open this setting you will also have options on what voice command you want to to work (incoming calls, alarm, camera, and music).

Users should be aware that when the phone is on vibrate, this feature WILL NOT WORK!

You may also have to speak quite loudly over your ringtone so the phone can hear your command.

You can also find this toggle in the S-Voice Settings.

Launch S-Voice, push menu, tap settings.  Turn on Voice Command for Apps.  If you tap on this, you can check on/off different apps to control.

Personally: I've never gotten it to work, no mattery what sound profile I'm using.
