Voice command can be activated on a device by saying the device's wakeup phrase. The default wakeup phrase is "Voice Command" but, can be changed to a word or phrase designated by the user.

To change the wakeup phrase:

Touch Tools
Touch Voice Command
Touch Customize Phrase
Type the word or phrase of your choice
Touch Done

Once the wakeup phrase is designated, speak the phrase to activate voice command.

Tips for using voice command:

Speak in a normal voice directly at the device
Speak commands as they appear on the screen
Respond to the voice prompts from the device as needed
To reduce the number of accidental voice command wake-ups, increase the length of your wakeup phrase
Try 3 or more syllables or multiple words
Speak Exit to exit voice command
If you press Mute Instructions the verbal replies from Voice Command will be muted
