Objectives: To evaluate the impact on voice of 2 hours of continuous oral reading. Methods: Fifty normophonic women underwent two sessions of voice loading in which the required intensity level varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. Ten expert judges evaluated the breathiness of one sentence recorded before and after each loading session. Pairs of stimuli were presented randomly to the judges, who were asked to designate the breathiest sample. Results: A significant decrease in breathiness was observed following both sessions, suggesting an improvement of voice subsequent to loading. When comparing the two intensity levels, no difference was found for breathiness after vocal loading. [less ▲]

The objective analysis of Western operatic singing voices indicates that professional singers can be particularly “out of tune”. This study aims to better understand the evaluation of operatic voices, which have particularly complex acoustical signals. Twenty-two music experts were asked to evaluate the vocal pitch accuracy of 14 sung performances with a pairwise comparison paradigm, in a test and a retest. In addition to the objective measurement of pitch accuracy (pitch interval deviation), several performance parameters (average tempo, fundamental frequency of the starting note) and quality parameters (energy distribution, vibrato rate and extent) were observed and compared to the judges’ perceptual rating. The results show high intra- and inter-judge reliability when rating the pitch accuracy of operatic singing voices. Surprisingly, all the parameters were significantly related to the ratings and explain 78.8% of the variability of the judges’ rating. The pitch accuracy evaluation of operatic voices is thus not based exclusively on the precision of performed music intervals but on a complex combination of performance and quality parameters.

Purpose: Although a global picture exists of teachers’ voice demands in general, few studies have compared specific groups of teachers to determine whether some are more at risk than others. This study compared vocal loading of kindergarten and elementary school teachers; professional and non-professional vocal load was determined for both groups. Method: Twelve kindergarten and twenty elementary school female teachers without voice problems were monitored during one workweek using the Ambulatory Phonation Monitor. Vocal loading parameters analyzed were F0, SPL, time dose, distance dose and cycle dose. Results: Comparisons between the groups showed significantly higher cycle dose and distance dose for kindergarten teachers than for elementary school teachers, in both professional and non-professional environments. Professional and non-professional voice use comparisons showed significant differences for all parameters, indicating that vocal load was higher in the professional environment for both groups. Conclusions: The higher vocal doses measured in kindergarten teachers suggest that particular attention should be paid to this specific group of teachers. Although non-professional vocal load is lower than professional vocal load, it is important to take both into account because of their cumulative effects. [less ▲]

A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers (1). The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order to better understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (N = 50) participated in the study. The analytical method described in the reference paper (1) has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices. [less ▲]

This study aims to validate our method for measuring accuracy in a melodic context. We analysed the popular song “Happy Birthday” sung by 63 occasional and 14 professional singers thanks to AudioSculpt and OpenMusic (Ircam, Paris, France). In terms of evaluation of the pitch interval deviation, we replicated the profile of occasional singers described in the literature (the slower the performance, the more accurate it is). Our results also confirm that the professional singers sing more accurately than occasional singers but not when a Western operatic singing technique is involved. These results support the relevance of our method for analysing vocal accuracy of occasional and professional singers and led us to discuss adaptations to be implemented for analysing the accuracy of operatic voices.

Objective: The operatic singing technique is frequently employed in classical music. Several acoustical parameters of this specific technique have been studied but how these parameters combine remains unclear. This study aims to further characterize the Western operatic singing technique by observing the effects of melody and technique on acoustical and musical parameters of the singing voice. Methods: Fifty professional singers performed two contrasting melodies (popular song and romantic melody) with two vocal techniques (with and without operatic singing technique). The common quality parameters (energy distribution, vibrato rate and extent), perturbation parameters (standard deviation of the fundamental frequency, signal-to-noise ratio, jitter and shimmer) and musical features (fundamental frequency of the starting note, average tempo, and sound pressure level) of the 200 sung performances were analyzed. Results: The results regarding the effect of melody and technique on the acoustical and musical parameters show that the choice of melody had a limited impact on the parameters observed, whereas a particular vocal profile appeared depending on the vocal technique employed. Conclusions: This study confirms that vocal technique affects most of the parameters examined. In addition, the observation of quality, perturbation and musical parameters contributes to a better understanding of the Western operatic singing technique. [less ▲]

Objective: The quality of a music performance can be lessened or enhanced if the performer experiences stressful conditions. In addition, the quality of a sung performance requires control of the fundamental frequency of the voice, which is particularly sensitive to stress. The present study aimed to clarify the effects of stress on singing voice accuracy. Methods: Thirty-one music students were recorded in a stressful condition (i.e., a music examination) and a non-stressful condition. Two groups were defined according to the challenge level of the music examination (first and second music levels). Measurements were made by self-reported state anxiety (CSAI-2R questionnaire) and by observing heart rate activity (electrocardiogram) during each performance. In addition, the vocal accuracy of the sung performances was objectively analyzed. Results: As expected, state anxiety and heart rate were significantly higher on the day of the music examination than in the non-stressful condition for all the music students. However, the effect of stress was positive for the first-year students but negative for the second-year students, for whom the music examination was particularly challenging. In addition, highly significant correlations were found between the intensity of cognitive symptoms and the vocal accuracy criteria. Discussion: This study highlights the contrasting effects of stress on singing voice accuracy but also the need to consider the challenge level and perception of the symptoms in experimental and pedagogical settings.

Objectifs - Cette étude quantifie l’usage vocal professionnel et extra-professionnel chez des enseignantes en différenciant deux niveaux scolaires : le maternel et le primaire. L’objectif est d’identifier le contexte (professionnel versus extra- professionnel) ainsi que le niveau scolaire (maternel versus primaire) requérant la charge vocale la plus importante. Méthodologie - Le comportement vocal de 21 enseignantes du maternel et de 20 enseignantes du primaire a été accumulé à l’aide d’un dosimètre pendant une semaine de travail (5 jours). Les paramètres analysés sont les suivants : l’intensité vocale, la fréquence fondamentale, la durée de phonation, le nombre de vibrations et la distance parcourue par les plis vocaux. Résultats - Comme attendu, le contexte professionnel est associé à des valeurs significativement plus élevées que le contexte extra-professionnel pour tous les paramètres mesurés. Par ailleurs, la comparaison entre les deux groupes montre des valeurs significativement plus élevées chez les enseignantes du maternel pour le nombre de vibrations et la distance parcourue par les plis vocaux. Conclusions - Le risque de développer des pathologies liées à la charge vocale est principalement associé à l’usage vocal professionnel des enseignantes, et il semble davantage présent chez les institutrices du niveau maternel que chez celles du primaire.

Thème général : le choix du traitement concernant les cancers glottiques à un stade précoce reste controversé. Les deux principaux traitements sont la chirurgie endoscopique au laser et la radiothérapie. Nous nous sommes intéressée aux conséquences des traitements sur une fonction importante, à savoir la phonation. Hypothèse de recherche : la qualité vocale des patients ayant souffert d’une tumeur T1a du plan glottique varie en fonction du traitement reçu, à savoir une résection endoscopique au laser CO2 ou une radiothérapie. Matériel et méthodes : nous avons recruté 18 patients traités par cordectomie, 7 traités par radiothérapie et 31 sujets contrôles. Un bilan vocal recommandé par l’European Voice Society a été réalisé chez tous les participants. Ce bilan comprenait des mesures acoustiques, aérodynamiques et des mesures perceptives (évaluation par le sujet lui-même ainsi que par un jury naïf composé de 38 juges). Résultats : les sujets traités par cordectomie obtiennent un score au jitter plus élevé et une étendue fréquentielle réduite par rapport aux sujets contrôles. Leur temps maximum phonatoire est plus faible alors que leur Mean flow rate est plus élevé par rapport aux sujets contrôles. Leurs scores au VHI total ainsi qu’à l’échelle physique sont plus élevés. Au niveau des mesures acoustiques, aérodynamiques et perceptives nous n’obtenons pas de différence significative entre les patients traités par cordectomie et ceux traités par radiothérapie. On constate néanmoins que les voix des sujets traités par cordectomie ont tendance à être jugées par le jury comme moins altérées. Conclusion : notre étude ne permet pas d’affirmer la supériorité d’un des traitements en ce qui concerne la qualité vocale post-traitement. L’analyse perceptive réalisée par un jury naïf permet d’observer que les voix des sujets traités pas radiothérapie ont tendance à être jugées comme étant légèrement plus altérées que celles des sujets traités pas cordectomie. Bien que certains prolongements soient possibles, notre étude apporte néanmoins une évaluation multiparamétrique de la qualité vocale après un cancer des cordes vocales classé T1a et traité soit par cordectomie endoscopique au laser CO2 soit par radiothérapie externe. Elle est la première à utiliser un jury naïf dans l’évaluation perceptive de la qualité vocale. [less ▲]

Professional singers are expected to sing in tune. However, when an operatic singing technique is employed, the objective measurement of the vocal accuracy (i.e. pitch interval deviation) shows particularly low scores, whatever the melody performed. This study focuses on the perceptual judgment of operatic voices in order to observe the evaluation process of singing voice accuracy by music experts and non-experts. In addition, this study aims to better understand the relationship between the subjective and objective measurements of operatic singing voices. 22 music experts and 22 non-experts paired in age and gender participated in a test and a retest (8 to 15 days in between). Fourteen sung performances performed by professional operatic singers were presented with a pairwise comparison paradigm. The participants were asked to indicate the most “in tune” melody for each pair (N = 91). The performances obtained thus a ranking by each judge. In addition, the 14 sung performances were objectively analyzed in order to confront the objective measurement of singing voice accuracy with the perceptual rating of the judges. Computing the variances of rank differences between the test and the retest, we observed that 20 music experts and 16 non-experts were consistent in their judgments. Among each group, the correlations between consistent raters were positive. However, 67.38% of these correlations were significant (p < .05) for the music experts whereas only 42.10% were significant for the non-experts. In addition, no relationship occurred between the objective measurements (from 9.5 to 115.5 cents, M = 40.57, SD = 34.42) and the perceptual ratings, except for two music experts. This study highlights the consistency of a judge when rating operatic singing voices and the difference between music experts and non-experts concerning the inter-judges reliability. Despite the fact that the majority of the music experts used similar strategies to evaluate the vocal accuracy of operatic voices, their judgment was obviously not linked with the objective measurement of vocal accuracy. This finding supports the tolerance of music expert listeners regarding the singing voice accuracy of operatic singers. Furthermore, this study provides some directions about the perception of operatic singing voices, which are particularly complex. [less ▲]

A previous study highlighted that objective and subjective measurements of vocal accuracy are highly correlated when the rating is done by musicians and that 81% of their variance was explained by the pitch interval deviation and the number of tonality modulations (Larrouy-Maestri, Lévêque, Schön, Giovanni, & Morsomme, 2013). However, the general audience is not expert in music. This study aims to observe the vocal accuracy assessment done by non musicians. Eighteen non musicians were asked to rate on a 9-point scale the global pitch accuracy of 166 vocal performances sung by untrained singers. This database was presented two times (T1 and T2) in a random order. The sung performances were objectively analyzed regarding three criteria: pitch interval deviation, number of tonality modulations and number of contour errors. The results show an intraclass correlation coefficient of .89 (p < .01) among the non experts and a mean intra-judges Spearman correlation of .66 (SD = .06) between T1 and T2. There is also a significant correlation between the acoustic measurements and the mean ratings (r(166) = .809; p < .01), with higher scores for accurate performances. Confronted with the music experts of the previous study, the judgment of the non experts correlated with the musicians ratings (r(166) = .840; p < .01). However, a Mann Whitney test showed that the rating of non experts was globally more severe than the experts one (p = 009). In addition, the regression analysis showed that only the pitch interval deviation criterion was considered in their judgment, explaining 66% of the variance of the judges. This study highlights the reliability and the objectivity of non musicians in the vocal accuracy assessment. Moreover, an effect of music expertise is observed concerning the severity of the rating and the vocal accuracy assessment process. [less ▲]

A previous study highlighted the objectivity of music experts when rating the vocal accuracy of sung performances (Larrouy-Maestri, Lévêque, Schön, Giovanni, & Morsomme, 2013). However, in an ecological context, numerous factors can influence the judges’ assessment of a music performance. This preliminary study aims to examine the effect of the music level of the performers on the evaluation of singing voice accuracy and to explore subjective factors which could influence the assessment. The same sung melody, performed by first and second year students of music conservatory (N = 31), was recorded in the context of their solfeggio examination. The jury, constituted of four music experts, was asked to rate the global pitch accuracy of each student. Two criteria (pitch interval deviation and tonal center deviation) were objectively measured and subjective data about the feeling of the students during the performance (e.g. anxiety level, enjoyment of singing) were collected through questionnaires. The results showed that the criteria used by the jury differed according to the music level of the students. Indeed, while the score of the jury correlated significantly with the vocal accuracy of the second year students, their assessment seemed more subjective concerning the first year students. Interestingly, the score of the jury was significantly correlated with the enjoyment of singing of the first year students and not with the objective measurements (pitch interval deviation and tonal center deviation) anymore. This preliminary work shows the effect of the music level of the performers on the evaluation of singing voice accuracy. Besides the educational implications of these findings, this study describes a promising method for the investigation of subjective factors, which influence the vocal assessment in an ecological context.
