Significant differences were obtained for CPPS measures in sustained vowel tasks. Female participants were found to have a greater mean than the male participants. Trained singers were found to have greater means than untrained singers and non-singers. Results: Significant differences were obtained at p < 0.05 between the genders (male and female) for different tasks and different cepstral parameters. Statistical Package for Social Sciences (SPSS), version 16.0 was used. Statistical analyses were done for the analyzed data. Recordings were done, and then acoustic (cepstral) analyses were done through PRAAT software. They were asked to undergo three tasks: sustained vowel /a/, oral passage reading, and singing task. The subjects were screened for speech, language, and hearing defects or any other abnormalities. Materials and methods: A total of 180 normal-speaking adults within the age range of 20–45 years were considered for the study, and they were divided into three groups: trained Hindustani classical singers (30 males and 30 females), untrained singers (30 males and 30 females), non-singers (30 males and 30 females). All rights reserved.Aim: The present study had the aim to obtain the cepstral measure of trained singers, untrained singers, and non-singers for the sustained vowel /a/, oral passage reading, and singing of the national anthem. Clinicians may consider using CPPS to complement clinical voice evaluation and screening protocols.Īcoustic measures Analysis of Dysphonia in Speech and Voice Dysphonia Praat Smoothed cepstral peak prominence.Ĭopyright © 2017 The Voice Foundation. CPPS measures from both programs were significantly and highly correlated (r = 0.88, P < 0.001).Ī single acoustic measure of CPPS was highly predictive of voice disorder status using either program. ![]() CPPS measures derived from Praat were uniquely predictive of disorder status above and beyond CPPS measures from ADSV (χ 2(1) = 40.71, P < 0.001). Results showed acceptable overall accuracy rates (75% accuracy, ADSV 82% accuracy, Praat) and area under the ROC curves (area under the curve = 0.81, ADSV AUC = 0.91, Praat) for predicting voice disorder status, with slight differences in sensitivity and specificity. Relationships between CPPS measures from the programs were determined. Logistic regression and receiver operating characteristic (ROC) analyses were used to evaluate and compare the diagnostic accuracy of CPPS measures. Measures of CPPS were obtained from connected speech recordings of 100 subjects with voice disorders and 70 nondysphonic subjects without vocal complaints using commercially available ADSV and freely downloadable Praat software programs. This is a retrospective cross-sectional study. The purposes of this study were to (1) determine and compare the diagnostic accuracy of a single acoustic measure, smoothed cepstral peak prominence (CPPS), to predict voice disorder status from connected speech samples using two software systems: Analysis of Dysphonia in Speech and Voice (ADSV) and Praat and (2) to determine the relationship between measures of CPPS generated from these programs. ![]()
