Abstract: A standard filler, or garbage model, is calculated for the detection of out of vocabulary utterances. Gobal statistical parameters are calculated (116) based upon the statistical parameters for new training data and a garbage model (118) is updated based upon the global statistical parameters. This is carried out on-line while the user is enrolling the vocabulary. The garbage model is preferably an average speaker model, representative of all the speech data enrolled by the user to date. The garbage model is preferably obtained as a by-product of the vocabulary enrollment procedure and is similar in it characteristics and topology to all the other regular vocabulary HMMs.
