Speaker identification in the absence of inter-subject differences in glottal source characteristics
Ralph O. Coleman · The Journal of the Acoustical Society of America · 1973
Speaker pairs can be identified as being composed of the same or two different speakers with better than 90% accuracy when the normal inter-subject differences in the glottal source characteristics are equalized. While between-subject differences in identifiability are relatively large, male speakers as a group retain a significantly greater degree of identifiability under the experimental conditions than do females.
