The Analysis of Voice Quality in Speech Processing
Abstract. Voice quality has been defined as the characteristic auditory colouring of an individual's voice, derived from a variety of laryngeal and supralaryngeal features and running continuously through the individual's speech. The distinctive tone of speech sounds produced by a particular person yields a particular voice. Voice quality is at the centre of several speech processing issues. In speech recognition, voice differences, particularly extreme divergences from the norm, are responsible for known performance degradations. In speech synthesis on the other hand, voice quality is a desirable modelling parameter, with millions of voice types that can be distinguished theoretically. This article reviews the experimental derivation of voice quality markers. Specifically, the use of perceptual judgements, the long-term averaged spectrum (LTAS) and prosodic markers is examined, as well as inverse filtering for the extraction of the glottal source waveform. This review sugges...
