In headset computers that leverage voice commands, often the user does not know what voice commands are available. In one embodiment, a method includes providing a user interface in a headset computer and, in response to user utterance of a cue toggle command, displaying at least one cue in the user interface. Each cue can correspond to a voice command associated with code to execute. In response to user utterance of the voice command, the method can also include executing the code associated with the voice command. The user can therefore ascertain what voice commands are available.
