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.
