Abstract: A method and system for providing adaptive interactive command response to a user, in which the user may protest upon incorrect recognition by the system of a command given by the user in response to question from the system. If the number of such protests reaches a value which exceeds a predetermined level of at least two protests, the decision model used for command recognition by the system is adjusted so that during a certain time interval (T) thereafter a more explicit indication is given to the user concerning one or more of the commands which are recognized. In the normal case, when such threshold value is not exceeded, no indication is given to the user of commands which have been recognized and the system proceeds directly to the next question.

Abstract: In a method of recognizing a control command in a system, in which a message from a user of the system is presented to the system in the form of speech and is recorded on a record carrier (11) by the system, and in which the control commands are presented to the system in the form of spoken commands, the speech is detected by a speech detector (15) during recording of the message. If no speech is detected for a specific time interval (T), recording is discontinued and a speech command recognizer (14) is rendered operative to recognize a control command to be presented to the system by the user.
