Psychophysical scaling of distorted speech.
Magnitude estimation and magnitude production procedures were used by ten normal-bearing subjects to scale the perceived distortion corresponding to the systematically varied physical distortion of a speech signal. The combined function based on the results of the two procedures exhibited a slope of 0.83, indicating that perceived distortion grows more slowly than physical distortion.
