“…A similar effect of speaking task was found in the study of Wolfe et al [27] who reported significantly higher ratings of the grade of dysphonia assessed on sustained vowel than those assessed on connected speech in both dysphonic and healthy subjects. The study of Lu et al [17] showed identical findings of the ratings of roughness and breathiness, while Zraick et al [18] also reported more severe judgments of dysphonia graded on sustained vowel.…”

Objective: To study the differences in perceptual ratings of mild and moderate dysphonia related to the speech task, and their impact on intrarater and interrater reliabilities. Patients and Methods: Voice recordings of 15 outpatients with mild or moderate dysphonia related to laryngopharyngeal reflux were presented to 6 female experienced judges blinded to the clinical state of the patients. From these, the GRBASI (Grade, Roughness, Breathiness, Asthenia, Strain, and Instability) evaluations were performed on connected speech and sustained vowel of the pretreatment voice recordings and absolute agreement, and both intrarater and interrater reliabilities were assessed. Results: The average GRBASI scores were significantly worse when performed on sustained vowel. Intrarater reliability substantially varied according to the judge and the task. Good interrater reliability was broadly found for the evaluations of all GRBASI components irrespective of the speech task. Concerning agreement, we only found absolute agreement between judges for G and R items assessed on text. Conclusion: Average grade of perceptual voice impairment, intrarater reliability, and agreement vary according to the speech task.

“…R was found to correlate quite well with jitter percent (Rho = 0.68), and B with shimmer (Rho = 0.63). These data have recently been corroborated by the findings of Wolfe et al [6], also using the Multidimensional Voice Program (MDVP) by Kay Elemetrics Corp.: in a sample of 51 pathological voices, multiple regression analysis across all voice types showed that a combination of NHR and shimmer was the best two-variable set of predictors of dysphonic severity (R = 0.63), accounting for 40% of the perceptual variance. Rough voices correlated more substantially with frequency perturbation measures than with amplitude perturbation measures, and shimmer was found to be the only significant predictor for breathiness.…”

What Determines the Differences in Perceptual Rating of Dysphonia between Experienced Raters?

Although the perceptual GRBAS scale for pathological voice quality has been found to be sufficiently reliable in clinical practice, even experienced raters disagree to some extent, and the degree of disagreement depends on the perceptual characteristics. We looked for a possible link between the degree of disagreement (65 voices; 2 experienced raters) and objective acoustical measurements. No significant correlation appeared between any acoustical parameter and the degree of disagreement for G. By contrast, the difference in perceptual rating of R was related to the amount of shimmer, and the difference in perceptual rating of B was related to some extent to the amount of jitter. Thus the presence of a strong breathy component in a pathological voice disturbs the rating of the rough component, and reciprocally.

“…This may be at odds with the study by Wolfe, Fitch and Martin (1997) comparing acoustic measures of different SD voice types with perceived severity in English SD. They reported that 'the most useful measure for the prediction of [perceptual] severity across voice types was noise-to-harmonic ratio' i.e., harshness and breathiness (Wolfe et al, 1997: 292).…”

Cross-linguistic study of vocal pathology: perceptual features of spasmodic dysphonia in French-speaking subjects

Clinical characterisation of Spasmodic Dysphonia of the adductor type (SD) in French speakers by Klap and colleagues (1993) appears to differ from that of SD in English. This perceptual analysis aims to describe the phonetic features of French SD. A video of 6 French speakers with SD supplied by Klap and colleagues was analysed for frequency of phonatory breaks, pitch breaks, harshness, creak, breathiness and falsetto voice, rate of production, and quantity of speech output. In contrast to English SD, the French speaking SD patients demonstrated no evidence pitch breaks, but phonatory breaks, harshness and breathiness were prominent features. This verifies the French authors' (1993) clinical description. These findings suggest that phonetic properties of a specific language may affect the manifestation of pathology in neurogenic voice disorders.
