OBJECTIVE: In this study, we aimed to determine the extent to which smoothed cepstral peak prominence (CPPS) can replace or complement the conventional acoustic measures of jitter, shimmer, and harmonic-to-noise ratio in the assessment of various types of dysphonia.
METHODOLOGY: A total of 60 males and 80 females were divided into two groups: dysphonic group and control group (30 males and 40 females in each group). The voice samples in the form of sustained vowel /a/ phonation and continuous speech were recorded and assessed using auditory perceptual analysis, acoustic analysis, and cepstral analysis.
RESULTS: Jitter was found to have the best predictive ability during sustained phonation, whereas CPPS was found to have the best predictive ability during continuous speech.
CONCLUSION: Cepstral analysis is as reliable as the conventional acoustic analysis in the diagnosis of dysphonia and to detect its severity. However, CPPS cannot replace conventional acoustic measures.
