“…The current results for CPPs (M = 16.3 dB; W = 16.1 dB) are comparable to those from previous studies including Núñez-Batalla et al (M = 16.0 dB; W = 16.4 dB) [27] and Angélica et al (16.44 dB) [27,28]. It was also higher than several previous studies [6,10,11,23].…”

Objectives:We aimed to standardize main vocal parameters including fundamental frequency (F0), jitter, shimmer, harmonic-noise ratio (HNR), and smoothed cepstral peak prominence (CPPs) for Mongolian adults with a normal voice across a range of age groups and genders. Methods: A total of 360 voice recordings belonging to adults between 20 and 79 years old were analyzed. An acoustic analysis was performed using the Praat Program with a sustained vowel /a/ or /α/. A one-way analysis of variance and an unpaired t-test were used to measure differences in voice parameters for the age groups and genders. Results: The mean value of F0 was higher in women (254.4 ± 17.9 Hz) compared with men (149.6 ± 15.3 Hz). The average jitter was 0.26% ± 0.12% (W = 0.25 ± 0.13) and the shimmer was 1.95% ± 0.45% (W = 2.01% ± 0.45%). The mean value of HNR was 11.9 ± 1.33 dB (W = 12.1 ± 1.36 dB) and CPPs was 16.3 dB (W = 16.1 dB). Conclusion: The F0 and HNR significantly increased with age for men. The F0 and CPPs decreased, whereas the shimmer and HNR increased with age in women.

“…13 Measurement does not require a stable fundamental frequency, unlike jitter, shimmer, and harmonics-to-noise ratio measures. 13,16 CPP is a reliable correlate to perceptual ratings of voice quality 17 and the severity and duration of voice disorders, 18 even for severely aperiodic signals such as tracheoesophageal voice. 19 Given these advantages and the large number of conditions in our study, we used CPP as an analog for voice quality.…”

Effects of Laryngeal Vibratory Asymmetry and Neuromuscular Compensation on Voice Quality

et al. 2021

Introduction: Vibratory asymmetry and neuromuscular compensation are often seen in laryngeal neuromuscular pathology. However, the ramifications of these findings on voice quality are unclear. This study investigated the effects of varying levels of vibratory asymmetry and neuromuscular compensation on cepstral peak prominence (CPP), an analog of voice quality.Study Design: In vivo canine phonation model. Methods: Varying degrees of vocal fold vibratory asymmetry were achieved by stimulating one recurrent laryngeal nerve (RLN) over 11 levels from threshold to maximal muscle activation. For each of these levels, phonation was induced at systematically varied combinations of neuromuscular compensation: three levels each of contralateral RLN stimulation (80%, 90%, and 100% of maximal), superior laryngeal nerve (SLN) activation (0%, 50%, and 100% of maximal), and airflow levels (500, 700, and 900 mL/s). Vocal fold symmetry was determined by assessing the opening phase of the vibratory cycle in highspeed video recordings. Voice quality was estimated acoustically by calculating CPP for each voice sample.Results: Eight hundred twenty-two phonatory conditions with varying degrees of vibratory asymmetry were evaluated. CPP was highest at vibratory symmetry. Increasing levels of asymmetry resulted in significant decreases in CPP. CPP increased significantly with increasing contralateral RLN activation. CPP was significantly higher at 50% SLN activation than 0% or 100% SLN activation.Conclusion: Voice quality, as approximated by CPP, is best at vibratory symmetry and deteriorates with increasing degrees of asymmetry. Voice quality may be improved with neuromuscular compensation by increased adduction of the contralateral vocal fold or increased vocal fold tension at mid-levels of SLN activation.

“…CPP is increasingly being recognized for quantifying harmonic spectral dominance in individuals with dysphonia (Burk & Watts, 2019; Hillenbrand, Getty, Clark, & Wheeler, 1995; Jannetts & Lowit, 2014; Maryn, Corthals, Van Cauwenberge, Roy, & De Bodt, 2010; Murton, Hillman, & Mehta, 2020). CPP is an automated measure that is independent of fundamental frequency (F0), indicates harmonic dominance, and has been shown to be equally applicable to sustained vowels and connected speech for both dysphonic and nondysphonic voices (Awan, Novaleski, & Yingling, 2013; da Silva Antonetti, Siqueira, de Gobbo, Brasolotto, & Silverio, 2020; Murton et al, 2020). Furthermore, it has also been observed that CPP correlates better than vocal intensity with both visual analog scales of overall voice quality made by experienced voice clinicians and single word intelligibility (SWIT) measures (da Silva Antonetti et al, 2020; Gaskill, Awan, Watts, & Awan, 2017; Watts & Awan, 2011).…”

In fact, CPP is well suited to confirm the previously found LSVT LOUD‐induced augmentation of laryngeal function including increase of glottal closure (Smith et al, 1995) and subglottal pressure (Ramig & Dromey, 1996).…”

This study compared acoustic and neural changes accompanying two treatments matched for intensive dosage but having two different treatment targets (voice or articulation) to dissociate the effects of treatment target and intensive dosage in speech therapies. Nineteen participants with Parkinsonian dysphonia (11 F) were randomized to three groups: intensive treatment targeting voice (voice group, n = 6), targeting articulation (articulation group, n = 7), or an untreated group (no treatment, n = 6). The severity of dysphonia was assessed by the smoothed cepstral peak prominence (CPPS) and neuronal changes were evaluated by cerebral blood flow (CBF) recorded at baseline, posttreatment, and 7-month follow-up. Only the voice treatment resulted in significant posttreatment improvement in CPPS, which was maintained at 7 months. Following voice treatment, increased activity in left premotor and bilateral auditory cortices was observed at posttreatment, and in the left motor and auditory cortices at 7-month follow-up. Articulation treatment resulted in increased activity in bilateral premotor and left insular cortices that were sustained at a 7-month follow-up. Activation in the auditory cortices and a significant correlation between the CPPS and CBF in motor and auditory cortices was observed only in the voice group. The intensive dosage resulted in long-lasting behavioral and neural effects as the no-treatment group showed a progressive decrease in activity in areas of the speech motor network out to a 7-month follow-up. These results indicate that dysphonia and the speech motor network can be differentially modified by treatment targets, while intensive dosage contributes to long-lasting effects of speech treatments.
