ABSTRACT A speaker verification system includes an input analyzer for analyzing a word spoken by a registered speaker or a person being verified, and outputting the result as an input pattern. A registration number designator is provided for outputting a regis- tration number and an input pattern buffer is provided for storing the input pattern. A verification reference pattern memory stores the input pattern as a verification reference pattern during regis- tration, designated by the registration number. A control refer- ence pattern memory stores, as control reference patterns, patterns which are obtained when several predetermined persons speak a predetermined password. A pattern matching unit is provided for determining first dissimilarities between the verification refer- ence pattern and the control reference patterns, a second dissimi- larity between the input pattern of the person being verified, which is obtained during the verification, and the verification reference pattern, and third dissimilarities between the input pattern and the control reference patterns. A control reference pattern designator is provided for selecting several first dissimi- larities consecutively, starting from the smallest of the first dissimilarities, to designate the control reference patterns cor- responding to the selected dissimilarities as the control reference patterns corresponding to the registration number. Finally, a judgement unit is provided for generating the confirmation signal when the second dissimilarity is less than both the third dissimi- larities corresponding to the designated control reference patterns and a predetermined threshold value.
