Display and Analysis of~Speech

The three most important speech processing applications are speech recognition, speech synthesis and speech coding. The display and analysis of speech signals provide knowledge of the important characteristics of speech, facilitating the design of speech processing algorithms for these applications. For example, examination of speech signals allows important properties to be identified which can subsequently be used to discriminate between different speech sounds, which is necessary in both speech recognition and speech synthesis applications. Similarly, structures in speech allow parametric models of speech production to be formulated that are fundamental to recognition, synthesis and coding.
