What is LPC analysis?

LPC (linear predictive coefficients) analysis is a technique for estimating the vocal tract transfer function, from which its poles, he formant frequencies, can be analytically calculated.

How do you find the LPC coefficient in Matlab?

[ a , g ] = lpc( x , p ) finds the coefficients of a p th-order linear predictor, an FIR filter that predicts the current value of the real-valued time series x based on past samples. The function also returns g , the variance of the prediction error.
