Title: A voice password system for access security

Abstract

A voice password system for access security using speaker verification technology has been designed for use over dial-up telephone lines. The voice password system (VPS) can provide secure access to telephone networks, computers, rooms, and buildings. It also has application in office automation systems, electric funds transfer, and ''smart cards'' (interactive computers embedded in credit-card-sized packages). As increasing attention is focused on access security in the public, private, and government sectors, the voice password system can provide a timely solution to the security dilemma. The VPS uses modes of communication available to almost everyone (the human voice and the telephone). A user calls the VPS, enters his or her identification number (ID) by touch-tone telephone, and then speaks a password. This is usually a phrase or a sentence of about seven syllables. On initial calls, the VPS creates a model of the user's voice, called a reference template, and labels it with the caller's unique user ID. To gain access later, the user calls the system, enters the proper user ID, and speaks the password phrase. The VPS compares the user's stored reference template with the spoken password and produces a distance score.
