Abstract

Of all the studies referenced in Chapters. 1 and 3, the majority have found positive correlations between various profile parameters and voice quality. The word “quality” is very loosely used in the context of audio processing. For example, one may refer to “perceptual quality,” “speech quality,” “audio quality,” “recording quality” etc. These usages must not be confused with the subject at hand—voice quality. From both signal processing and information theoretic perspectives, voice quality is an elusive entity. There is no consensus in the scientific community about its precise definition—quantitatively or even in a descriptive sense. It is in fact a complex entity that comprises a set of many (mostly) subjectively described characteristics, or sub-qualities that collectively represent it. These characteristics, or attributes of voice, give it its particular auditory flavor, and can also be thought of as comprising the overall quality of someone’s voice in a manner analogous to a sound mixer used in music production. Unfortunately, there is no consensus on even the number of sub-qualities that comprise voice quality. Regardless, some important ones are described in this chapter.
