Experiment 2 was an initial attempt to estimate auditory-perceptual ratings of overall dysphonia severity using CPP values. Experiment 1 identified CPP values to distinguish speakers with and without voice disorders. Treatment of voice disorders, to evaluate treatment efficacy, and monitor progress. Purpose The goal of this study was to employ frequently used analysis methods and tasks to identify values for cepstral peak prominence (CPP) that can aid clinical voice evaluation. Standardised use of CPP as a robust tool and facilitate its interpretation in the assessment and Normative CPP data reported in the study could potentially contribute to the Recording condition and gender were not found significant.Ĭonclusions: Smartphones can be used to record audio data of adequate quality for acoustic Task (lower CPP in connected speech compared to sustained vowels) while the effects of Our preliminary results suggest a significant effect of speech Collection ofĭata for the project is ongoing. Results: We report CPP data for young normophonic adults living in Ireland. Room using a head-mounted microphone, and remotely using the participants’ mobile phones.ĬPP values were extracted using Praat (Boersma & Weenink, 2023) and subsequentlyĪnalysed using a complex mixed-effect ANOVA, with two within-subject factors (recordingĬondition, speech task) and one between-subject factor (gender). Recordings were completed onsite in a sound insulated Participants produced a number of speech tasks (sustained vowels and sentences withĭifferent segmental composition). Method: Thirty four participants aged between 18 and 24 years were recruited (28 female). It aims to fill the gap with regard to CPP data collected remotely. This study aims to establish normative data for CPP for youngĪdults in Ireland and to determine the extent of CPP variability across genders, speech tasksĪnd recording conditions.
#CEPSTRAL PEAK PROMINENCE PRAAT SOFTWARE#
Vary significantly with recording conditions, analysis software used, speech tasks, and the ageĪnd gender of the speaker. Which clinicians would compare disordered voice analysis data. This paper deals with cepstral peak prominence smoothed (CPPS) distribution and its descriptive statistics as possible indicators of vocal health status.
Limited due to its relative conceptual complexity and also the lack of normative data against As the name suggests, these scripts owe a debt to the VoiceSauce suite of Matlab scripts developed by Shue et al. Measure of dysphonia in clinical voice assessment (Patel et al., 2018). This set of Praat scripts is designed to facilitate the extraction of spectral measures such as H1-H2, H1-A3, cepstral peak prominence, etc. Table 2 summarizes the technical information and the steps performed in Praat program. Objective dysphonia measures in the program Praat: Smoothed cepstral peak prominence and acoustic voice quality index. & Yanushevskaya, I., Establishing Cepstral Peak Prominence (CPP) normative data for young adults in Ireland: the impact of gender, speech task and recording conditions, ICPLA 2023, Salzburg, Austria, July 4-7, 2023īackground: Cepstral Peak Prominence (CPP) is currently recommended as a robust to-noise ratio (HNR), and smoothed cepstral peak prominence (CPPS).
