Purpose: The purpose of the present study was to investigate whether cepstral measures differ according to the measurement positions in a passage, upon controlling overall severity of voice disorders. Furthermore, the diagnostic value of perceptual estimates derived by cepstral measures in each position was explored. Methods: 35 patients with voice disorders and 35 normal controls were asked to read the standard passage ‘Ga-eul’. For each sample, sentence samples of 26-30 syllable length were trimmed in 3 positions (front, middle, rear) of the passage and cepstral peak prominence (CPP), L/H ratio, and their standard deviations (SDs) of were measured. Perceptually, overall severity from the CAPE-V was measured. Upon controlling the severity, cepstral measures were compared between groups and positions. The association of cepstral measures with perceptual severity was explored in each position. Diagnostic value of the perceptual estimates was also explored. Results: Results indicated that CPP of the rear position was lower than that of middle position, while SD of the L/H ratio of the rear position was higher than those of front and middle positions. On the other hand, not only the relationship between perceptual and cepstral measures, but also diagnostic value were the highest for the front position. Conclusions: It is highly recommended that the variability of the cepstral measures among positions should be taken into consideration in research and clinics.
