Objective: Vocal accuracy of a sung performance can be evaluated by two methods: acoustic analyses and subjective judgements. Acoustic analyses have been presented as a more reliable solution but both methods are still used for the evaluation of singing voice accuracy. This paper presents a first time direct comparison of these methods. Methods: 166 untrained singers were asked to sing the popular song « Happy Birthday ». These recordings constituted the database analyzed. Acoustic analyses were performed to quantify the pitch interval deviation, the number of contour errors and the number of tonality modulations for each recording. Additionally, eighteen experts in singing voice or music rated the global pitch accuracy of these performances. Results: A high correlation occurred between acoustic measurements and subjective rating. The total model of acoustic analyses explained 81% of the variance of the judges’ scores. Their rating was influenced by both tonality modulation and interval deviation. Conclusions: This study highlights the congruence between objective and subjective measurements of vocal accuracy within this first time comparison. Our results confirm the relevance of the pitch interval deviation criterion in vocal accuracy assessment. Furthermore, the number of tonality modulations is also a salient criterion in perceptive rating and should be taken into account in studies using acoustic analyses. [less ▲]

Vocal accuracy of a sung performance can be evaluated by two methods: acoustical analyses and subjective judgements. For one decade, acoustic analyses have been presented as a more reliable solution to evaluate vocal accuracy, avoiding the limitation of experts’ perceptive system and their variability. This paper presents for the first time a direct comparison of these methods. 166 occasional singers were asked to sing the popular song « Happy Birthday ». Acoustic analyses were performed to quantify the pitch interval deviation, the number of contour errors and the number of tonality modulations for each recording. Additionally, eighteen experts in singing voice or music rated the global pitch accuracy of these performances. The results showed a high inter-rater concordance within the judges. In addition, a high correlation occurred between acoustic measurements and subjective rating. The total model of acoustic analyses explained 81% of the variance of the judges’ scores. Their rating was influenced by both tonality modulations and interval deviations. This study highlights the congruence between objective and subjective measurements of vocal accuracy while the assessment is done by music or singing voice experts. Our results confirm the relevance of the “pitch interval deviation” criterion in vocal accuracy assessment. Furthermore, the “number of tonality modulations” is a salient criterion in perceptive rating and should be taken into account in studies using acoustical analyses. [less ▲]

The aim of this study is to establish relevant objective parameters for evaluating dysphonia following unilateral vocal fold paralysis. To do so, the study compares objective and perceptual voice measures. The objective measures were obtained using a voice analysis software (Evaluation Vocale Assistee), whereas the perceptual measures were established with the GIRBAS Scale (grade, instability, roughness, breathiness, asthenia, and strain). All measurements were performed on 40 voice samples: 28 dysphonic subjects with unilateral laryngeal paralysis, and 12 control subjects. The intra- and inter-judge agreements were fairly good, at least for control subjects. The six GIRBAS measures obtained from the pathological voices were higher than those from the control voices (p < 0.001) and the correlation between both groups was good. Grade, breathiness and asthenia correlated with the objective parameters that express the aperiodicity of the phonatory signal (p < 0.01), namely, the coefficient of variability of the fundamental frequency, the coefficient of variability of intensity, and jitter. Our findings suggest that the perceptual reality of laryngeal paralysis-induced dysphonia depends more on grade, breathiness and asthenia than it does on roughness or instability. [less ▲]
