Warped Linear Predictive Coding (WLPC) is an extension of traditional Linear Predictive Coding (LPC), which is a technique commonly used in speech processing for representing the spectral envelope of a digital signal. Traditional LPC analyzes a signal by estimating the coefficients of a linear filter that best approximates the signal in a least-squares sense. The key innovation in WLPC is the incorporation of a warping function that modifies the frequency scale in a non-linear manner.
