ABSTRACT:
A voice verification system in which multiple generic reference patterns are obtained by speaking the password in a number of different ways and in which a speaker specific reference pattern is generated by the speaker undergoing registration. A subset of the generic reference patterns are selected having the greatest similarity to the registered speaker's pattern. During verification, the speaker's identity is verified if the dissimilarity between the input pattern and the registered speakers reference pattern is both less than any dissimilarity between the input pattern and the selected generic reference patterns and also less than a threshold value.
