“…Therefore, the finding that patients showed higher F0 values than the normal controls could be explained by their voice quality characteristics. In a study by Lowell et al [25], in which voices with high roughness were compared to normal voices, CPP F0 of speakers with high roughness was significantly higher (227.61 ± 23.58 Hz) than that of speakers with normal voices (178.40 ± 24.21 Hz). Further, CPP F0 showed an increased pattern for speakers with strained voices.…”

Objective: To evaluate esophageal speech quality in patients after total laryngectomy using cepstral, spectral and time-based measures. Patients and Methods: The subjects were all males and included 20 total laryngectomy patients and 20 age-matched normal controls. The sustained vowel /a/ was measured using the tools of MDVP (Multi-Dimensional Voice Program) and ADSV (Analysis of Dysphonia in Speech and Voice). Results: Compared to normal controls, esophageal speakers showed significantly lower values for cepstral peak prominence (CPP) and a low- to high-frequency spectral energy (L/H) ratio, but their mean CPP fundamental frequency (CPP F0) was higher. Highly negative correlations were found between CPP and jitter (percent jitter), shimmer (percent shimmer) and noise-to-harmonics ratio (NHR). Positive correlations were also found between L/H ratio and CPP. CPP F0 showed a positive correlation with F0, shimmer and NHR. In addition, CPP and L/H ratio parameters indicated an area under the curve of 0.93 or higher compared to that for time-based measures. Conclusion: This study showed that cepstral and spectral analyses are more effective than time-based analysis in examining the voice quality of alaryngeal speakers. The present findings are expected to contribute to establishing the baseline for voice quality characteristics in total laryngectomy patients.

“…Cepstral measures have been shown to highly correlate with dysphonia severity (Awan & Roy, 2006), thus a possible explanation for the disparity between the study by Lowell et al (2012) and Brinca et. al.…”

“…Unfortunately, a study examining the correlation between 19 common acoustic measures and a clinician-based perceptual voice assessment protocol, the Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scale, found that no acoustic measure was well-correlated with strain (Bhuta, Patrick, & Garnett, 2004). More recently, the perception of strain has been shown to have strong relationship with cepstral measures and moderate relationship with spectral measures in a group of dysphonic speakers with predominately strained voice quality (Lowell, Kelley, Awan, Colton, & Chan, 2012). However, when the primary factor of the cepstral measure – cepstral peak prominence -- was examined in a group of individuals with nonhomogeous diagnoses, no significant correlation was found between cepstral peak prominence and the perception of strain (Brinca, Batista, Tavares, Gonçalves, & Moreno, 2014).…”

Purpose The acoustic measure Relative Fundamental Frequency (RFF) was investigated as a potential objective measure to track variations in vocal effort within and across individuals. Methods Twelve speakers with healthy voices created purposeful modulations in their vocal effort during speech tasks. RFF and an aerodynamic measure of vocal effort, the ratio of sound pressure level to subglottal pressure level, were estimated from the aerodynamic and acoustic signals. Twelve listeners also judged the speech samples for vocal effort using the visual sort and rate method. Results Relationships between RFF and both the aerodynamic and perceptual measures of vocal effort were weak across speakers (R2 = 0.06–0.26). Within speakers, relationships were variable, but much stronger on average (R2 = 0.45–0.56). Conclusions RFF showed stronger relationships between both the aerodynamic and perceptual measures of vocal effort when examined within individuals relative to across individuals. Future work is necessary to establish these relationships in individuals with voice disorders across the therapeutic process.

“…Increased high-frequency spectral energy may be associated with dysphonia, and studies have also demonstrated that a small L/H SD is also present in speakers with dysphonia. 22 KayPENTAX's ADSV program also computes a multivariate index measure, the CSID, based on regression algorithms that incorporate the cepstral and spectral measures of CPP, L/H ratio, and L/H ratio SD. The CSID approximates a 100-point severity scale that can be compared with auditory-perceptual ratings and has been validated for the CAPE-V sentences in adults.…”

Sustained vowel utterance and continuous speech samples provide consistent measures of fundamental frequency. Frequency-based analysis of sustained vowel recordings improves the reliability of perturbation measures. Continuous speech recordings can be obtained in children and demonstrate good to excellent reliability across recordings. This suggests that frequency-based analysis of continuous speech may be more representative of a child's voice and therefore may be of use in the study both of the developmental changes of the pediatric voice as well as the study of vocal changes pretreatment and posttreatment in children with voice disorders.
