But Moto Voice does the same thing OK Google does if it's not a special Motorola command. (So, if your catch phrase is "OK Droid Turbo", then saying, "OK Droid Turbo, what time is the Women's World Cup semifinal game on TV tonight?" should give the same answer as the Google search app's "OK Google, etc." from anywhere, including the lockscreen, including when the phone is on battery.)
The special Moto commands are things like "What's Up?" to read off unread notifications, etc.
Unless I am missing something...
