“…As the ≥11 group included teenagers, it is logical that these values would begin to approximate adult values as young men experience the decrease in F0 associated with puberty 79,80 . The decrease in CPPSD following voice therapy was unexpected, as it has been previously reported that greater CPPSD reflects increased laryngeal flexibility 47,61,81 . The fact that CPPSD decreased in the current study may indicate that children employed less prosodic variation following voice therapy as they were concentrating on producing stimuli with forward resonance.…”

“…There are currently no studies characterizing auditory‐perceptual features of normal pediatric voices, but studies have found higher soft phonation index in children under five, 68 and lower harmonic‐to‐noise ratios in children under eight 69 . Additionally, measures such as jitter, shimmer, and CPP have been observed to improve with increased age 58,61 …”

This study employed acoustic measures as well as auditory-perceptual assessments to examine the effects of voice therapy in children presenting with benign vocal fold lesions.Methods: A retrospective, observational cohort design was employed. Sustained vowels produced by 129 children diagnosed with benign vocal fold lesions were analyzed, as well as connected speech samples produced by 47 children. Treatment outcome measures included Consensus of Auditory-Perceptual Evaluation of Voice (CAPE-V), jitter, shimmer, Noise-to-Harmonic Ratio (NHR), cepstral peak prominence (CPP), and Low-to-High Ratio (LHR) on sustained vowels, and CPP and LHR on connected speech.Results: Following voice therapy, significant improvements in CAPE-V ratings (p < 0.001) were observed. Additionally, jitter (p = 0.041), NHR (p = 0.019), and CPP (p < 0.01) on sustained vowels, and CPP (p = 0.002), and LHR (p = 0.008) on connected speech significantly improved following voice therapy. CPP increased with age in males but did not change in females. CAPE-V ratings and perturbation measures indicated that dysphonia was more severe in younger children pre and posttherapy.Conclusions: Auditory-perceptual and acoustic measures demonstrated improved voice quality following voice therapy in children with dysphonia. CPP effectively quantified voice therapy gains and allowed for analysis of connected speech, in addition to sustained vowels. These findings demonstrate the value of CPP as a tool in assessing therapy outcomes and support the efficacy of voice therapy for children presenting with vocal fold lesions.

“…CPP can vary significantly based on the stimuli selected for analysis. Differences are seen based on the selection of sustained vowels 17,27 or phonemes present in continuous speech samples [27][28][29][30][31][32][33] . As continuous speech stimuli varies in the amount of voiced productions and articulatory patterns used, some researchers have used the all-voiced sentences for analysis 5 .…”

“…Although numerous studies have shown the strong relationship between dysphonia and CPP 3,[7][8][9][10][11][12][13][14][15][16] , significant external factors unrelated to dysphonia may also influence CPP. These factors include patient-controlled factors (such as prosodic changes in loudness or fundamental frequency [17][18][19][20][21][22][23][24] ), recording environment or microphone used 25,26 , stimuli type (sustained vowel, continuous speech), and phonemes present in stimuli 17,[27][28][29][30][31][32][33] , as well as the program used to calculate CPP values 9,10,15,24,26,27,[34][35][36] . Therefore, it is essential that clinicians using CPP reduce as many of these external factors as possible when comparing across patients or within the same patient across time points (i.e., before and after therapy).…”

Objectives: The acoustic measure of cepstral peak prominence (CPP) is recommended for the analysis of dysphonia. Yet, clinical use of this measure is not universal, as clinicians and researchers are still learning the strengths and limitations of this measure. Furthermore, affordable access to specialized acoustic software is a significant barrier to universal CPP use. This article will provide a guide on how to calculate CPP in Praat, a free software program, using a new CPP plugin. Additionally, important external factors that could influence CPP measures are discussed, and suggestions for clinical use are provided.Methods: A tutorial on installing and using the new CPP plugin is provided. Sample results using this plugin are provided for participants in the Perceptual Voice Qualities Database1. Results: Using the CPP plugin, CPP values calculated with and without voicing detection were significantly correlated with the auditory-perceptual ratings of dysphonia. Discussion: This article provides a comprehensive tutorial for installing and using the CPP plugin in Praat, a free software program. As CPP becomes more widely used by clinicians and researchers, it is important to consider external factors that may inadvertently influence CPP values. Controlling for these external factors will aid in reducing variability across CPP values, which will make CPP a valuable tool for both clinical and research purposes.
