Speaker Recognition in Speech Communications
Gary L. Holmgren, Edward J. Morrison · The Journal of the Acoustical Society of America · 1963
A study was performed to investigate the definition of a perceptual space within which listeners locate voices, to the end that the effects o[ manipulating speaker, hardware, and listener characteristics can be measured, and, eventually, that specifications for elements of a voice-communications system might be prepared to produce the desired system characteristic. In the experiments reported, taped speech samples were rated by listeners, using Osgood's semantic differential method. Previous study indicated only four basic dimensions were required to account for ratings given speakers on a large number of characteristics. In a second experiment, a reduced number of characteristics, selected from the original list as best representing the four necessary factors, was used by listeners to rate recorded speaker samples. The experimental design allowed examination of the effects on ratings due to differences between listeners, due to repetition of the rating task, and to order of speaker presentation. Results of these examinations and the following are presented: (1) adequacy of the original factors in accounting for listeners' ratings; (2) differentiation between speakers; (3) reliability of ratings; and (4) familiarity of previously unheard voices.
