A practical implementation of speaker verification

This paper describes a pilot study in the implementation of a speaker verification system. Ten individual (seven males and three females) from the voice group at SCI served as enrollees for the verification system. In addition, four other group members acted as impostors/infiltrators in order to try to circumvent the system. The system employed was a Votan VPC-2000 in an IBM-PC. The enrollees to the system trained it with their name, employee number, and a password. The training was conducted on day 1 of the experiment and subsequently on days 14, 28, and 42. Each subject tested the system every working day for 2 months against each of their four training templates. Two of the four impostors were provided with the name, employee number, and password for each of the “authorized” subjects, while the other two impostors were not given this information. Each of the impostors attempted to access the system during the 2-month experimental period. Data analysis is currently underway. Specific aspects of the instructions were effective and how future instructions data and results will be discussed.
