ABSTRACT
Speech processing comprises automatic speech recognition, speech synthesis, speech coding, speech enhancement, speaker recognition and verification, language identification, and so on. This section discusses the application of artificial neural networks (ANNs) to these areas. The viewpoint will be that of an engineer; that is, the question we try to answer is, ‘How can ANNs be used to solve engineering problems in speech processing?’ We will present some conventional approaches to these problems and point out where ANNs could be applicable. As a lot of the ANN effort in speech processing seems to be concentrated around speech recognition, this will also be our focal point. Other areas will be briefly reviewed. Due to the breadth of the field and space limitations, this section can only remain superficial: more of a commented list of bibliographic references.
