The Assessment of Speech Quality
Raymond S. Nickerson, A. W. F. Huggins · 1977
Various methods that have been used to assess the quality of speech are reviewed. These methods are organized under three general topics: unidimensional quality assessment, judging of individual speech qualities, and multidimensional scaling. The importance of effects attributable to speech material, talkers and listeners is emphasized. The desirability of objective measures of speech quality is noted and some candidate measures are discussed. Finally, the relationship between quality assessment and intelligibility testing is briefly considered.
