Contextual push-to-talk: a new technique for reducing voice dialog duration

We present a technique in which physical controls have both normal and voice-enabled activation styles. In the case of the latter, knowledge of which physical control was activated provides context to the speech recognition subsystem. This context would otherwise be established by one or more steps in a voice dialog initiated by a conventional, single "push-to-talk" button.
