Warped linear prediction (WLP) in speech and audio processing
Unto Kalervo Laine, Matti Karjalainen, Toomas Altosaar · 2002
A linear prediction process is applied to frequency warped signals. The warping is realized by using orthonormal FAM (frequency modulated complex exponentials) functions. The general formulation of WLP is given and effective realizations with allpass filters are studied. The application of auditory WLP to speech coding and speech recognition has given good results.>
