Determining Perceptual Spaces for the Quality of Filtered Speech
Victor E. McGee · Journal of Speech and Hearing Research · 1965
Using one recorded voice, distorted in 15 different ways, a sample of listeners made similarity-with-respect-to-quality judgments for the complete paired comparison schedule. By means of an Eckart-Young type factoring procedure, four points of view among the listeners were isolated and the perceptual spaces for these points of view were determined. An implication of the “mean” point of view was the operation of two response sets labeled “lowest harmonics—YES” and “lowest harmonics—NO”.
