This book explains speech enhancement in the Fractional Fourier Transform (FRFT) domain and investigates the use of different FRFT algorithms in both single channel and multi-channel enhancement systems, which has proven to be an ideal time frequency analysis tool in many speech signal processing applications.

This book serves as a basic reference for thoseinterested in the application of metaheuristics to speech enhancement. Themajor goal of the book is to explain the basic concepts of optimization methodsand their use in heuristic optimization in speech enhancement to scientists,practicing engineers, and academic researchers in speech processing. Theauthors discuss why it has been a challenging problem for researchers todevelop new enhancement algorithms that aid in the quality and intelligibilityof degraded speech. They present powerful optimization methods to speechenhancement that can help to solve the noise reduction problems. Readers willbe able to understand the fundamentals of speech processing as well as theoptimization techniques, how the speech enhancement algorithms are implementedby utilizing optimization methods, and will be given the tools to develop newalgorithms. The authors also provide a comprehensive literature surveyregarding the topic.
