Evaluation of a high performance speaker verification system for access control
Jayant M. Naik, George R. Doddington · 2005
The results of an extensive evaluation of a speaker verification system for access control are presented. The system employs an algorithm based on the Principal Spectral Components representation derived from the short term spectrum of the speech signal. This system designed for access control applications has been evaluated using a 200 speaker population and a total of over 13,000 true speaker attempts and over 40,000 impostor attempts, both performed on line, over a 4-month period. A true speaker rejection rate of less than 1 % and an impostor acceptance rate of less than 0.1 % have been obtained.
