Abstract : I DENTIFIERS: Psychophysical, Semantic space. The relationships between physically specifiabl speech signals and psychologically perceived speech quality was investigated. A major objective was to examine the role of naturalness in the perception of quality and to relate physical properties of the speech signals to this factor. To exercise physical control over the speech signals (called voices) only one talker was used and his voice was subjected to controlled frequency distortion. A sample of male and female listeners provided three basic kinds of data: (a) preference judgments, (b) similarity judgments ov r ll pairs of voice distortions, and (c) semantic judgments made on each voice over a set of semantic scales. The preference data were used to determine a unidimen io l qu lity co i uum n he si ilarity data were a alysed as interstimulus distances to produce a multidimensional quality space. (Author)
