A Study on a Change of LPC Cepstrum Coefficients with Drunken Voice

Abstract

This paper describes the change of LPC cepstrum coefficients and detection between drunken voice and non drunken voice by LPC cepstrum coefficients. As a result of experiment, I show the possibility of judgment for a drunken voice and non drunken voice by using difference LPC cepstrum coefficients. It's very interested of a study on speech recognition for a drunken voice. Also, it's make of use to prevention and detection of drunken drivers.
