Name: Linear Prediction and Cross Synthesis
ID: m15478
Language: English (en)
Summary: Linear prediction coding (LPC) models a speech signal as a time-varying filter driven by an excitation signal. The time-varying filter coefficients model the vocal tract spectral envelope. “Cross synthesis” is an interesting special effect in which a musical instrument signal drives the digital filter (or vocal tract model), producing the sound of a “singing instrument.” The theory and implementation of linear prediction are presented in this module.
