Command Prefix For Voice Commands

摘要

Methods, systems, and products describe hands-free operation of a communications device. A user defines a command prefix that is recognized as preceding one of several voice commands. When the user speaks the command prefix, a processor identifies the spoken command prefix and treats a next spoken word as one of the voice commands. The voice command may then be executed for control. The command prefix thus helps avoid control confusion when the voice command is inadvertently spoken.
