How to use LPC 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.
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.
What is LPC in speech recognition?
Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model. LPC is the most widely used method in speech coding and speech synthesis.
