The relationship between psychoacoustic evaluation of hoarse voices and acoustic indices (pitch perturbation quotient, PPQ; and amplitude perturbation quotient, APQ) was investigated by the rating and paired comparison methods. Synthesized voices were utilized in order to control the acoustic indices.<BR>The results indicated that some psychoacoustic paramenters show a strong correlation with the acoustic indices. Especially a linear correlation was seen between the rating scores of"grade of hoarseness"and the logarithm of the values of PPQ. This suggests that Weber-Fechner's law might be applied to psychoacoustic evaluation of PPQ.<BR>As a method of evaluation, paired comparison was better than rating from the view-point of consistency among the listeners.
