Set wake up command

[Lanny Lin]

I see other people saying you can set wake up command on S3 to your own voice command, but I cannot find the option anywhere in my menus.

After opening S Voice and go to settings, I only see Wake up command with a checkbox under Wake Up section.

Can someone tell me where I can find this command? I am using an unlocked (used to be AT&T) S3 i9300 running Android version 4.3.
Thanks a bunch!

I figured it out. Set screen lock to off, and then you can see the command. After setting the commands, you can enable screen lock again.
