System and method for low overhead time domain voice authentication
First Claim
Patent Images
1. A method of generating a voice identification in a time domain comprising:
- using a processor to identify in a voice signal an initial rise time portion, an initial fall time portion, a second rise time portion, a second fall time portion and a final oscillation time portion, said time portions forming a period of said voice signal;
measuring the time value of each of said time portions;
digitizing the time value of each of said time portions into a first predetermined number of bits; and
,concatenating said bits to form said voice identification.

Abstract
A system and method are provided to authenticate a voice in a time domain. The initial rise time, initial fall time, second rise time, second fall time and final oscillation time are digitized into bits to form at least part of a voice ID. The voice IDs are used to authenticate a user'"'"'s voice.
