Abstract

A pattern matching system compares an input signal with a set of models in order to map the signal to one of a set of classes. A spoken language interface comprises an automatic speech recognition system (ASR) for recognising speech inputs from a user, a speech generation system for providing speech to be delivered to the user, and a store of predicted utterances and compares a speech input from a user with those utterances to recognise the speech input. An adaptive learning unit includes an adaptive algorithm for automatically adapting the models of stored utterances in response to use of the Interface by one or more users. The adaptive learning may be on the basis of a recognition hypotheses selected and weighted according to their quality, determined by a hybrid confidence measure, their quantity, and their age.
