Homomorphic analysis and synthesis of speech generated by an all-pole model

Abstract

Homomorphic filtering is one of various schemes used in digital signal processing, particularly in processing speech signals. Homomorphic filtering strategy depends upon the type of operation under which the signals under focus have been combined. A system based on speech generation through the convolution of an all-pole model impulse response with an excitation signal has been discussed in this thesis. A study with examples on the effect of various weighting windows and their width has been attempted.
