Abstract
A barge-in detector for use in connection with a speech recognition system forms a prompt replica for use in detecting the presence or absence of user input to the system. The replica is indicative of the prompt energy applied to an input of the system. The detector detects the application of user input to the system, even if concurrent with a prompt, and enables the system to quickly respond to the user input.
