ABSTRACT:
Multiple examples of a vocabulary of known words are recorded. The examples of each word are temporally aligned and supplied to a neural net which identifies unique features of each word which discriminate it from other words in the vocabulary. These unique features are integrated with parameters of a Hidden Semi-Markov model and stored. Speech signals from unknown words are then compared with the stored unique feature information after syntax restriction.
