System and method for establishing a communication link using user-specific voice data parameters as a user discriminator

Abstract

A system and method for establishing a communication link, wherein the system includes a communications unit (60, FIG. 3) having a vocoder (62) for providing user-specific voice data in the form of a unique set of speech characteristic model parameters for each authorized user. The method (200, FIG. 8) includes the steps of providing user-specific voice data via a connection training method (FIGS. 5, 6, or 7), collecting a sample of speech characteristics from a user desiring to access the communication unit (206, FIG. 8), comparing the sample with the user-specific voice data (212), granting the user access to the communication unit to establish a communication link with another communication unit if the sample is comparable with the user-specific voice data (215), and denying the user access to the communication unit if the sample is incomparable with the user-specific voice data (220).
