Abstract :
Multipulse LPC analysis can substantially eliminate the pitch-related bias in the LPC filter parameters. However, the procedure is computationally intensive. We present a more efficient algorithm, based on the autocorrelation method of linear prediction, which has application in voice synthesis and vocal-tract area-function recovery.
