Abstract

Speech has an important role for communication among human beings. It is not only a tool for communication, but also contains ample information about the speaker’s age, emotion, health, and identity. Presently, the importance of speech processing has increased in various fields like automatic speech recognition, speaker verification, and pathological speech prediction. Therefore we need some intelligent speech processing techniques that can be used in various applications. Since speech is a nonlinear and ...
