We investigated the accuracy of auditory inferences of personality of Belgian children with vocal fold nodules (VFN). External judges (N=57) were asked to infer the personality of normophonic (NP) children and children with VFN (N=10) on the basis of vowels and sentences. The auditory inferred profiles were compared to the actual personality of NP and VFN children. Positive and partly accurate inferences of VFN children’s personality were made on the basis of connected speech, while sustained vowels yielded negative and inaccurate inferences of personality traits of children with VFN. Dysphonic voice quality, as defined by the overall severity of vocal abnormality, conveyed inaccurate and low degrees of Extraversion. This effect was counterbalanced in connected speech by faster speaking rate that accurately conveyed higher degrees of Extraversion, a characteristic trait of VFN children’s actual personality.

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 ▲]

Nous avons analysé les dossiers de 1079 patients (754 femmes et 325 hommes) qui se sont présentés au CHU de Liège entre 2009 et 2013 pour une plainte vocale. Chez ces patients, nous avons répertorié 121 personnes sans profession (11%), 166 étudiants (16%), 215 retraités (20%), et 577 travailleurs (53%). Parmi ces 577 travailleurs, il y avait notamment 129 enseignants, 55 employés de bureau, 50 chanteurs, comédiens et musiciens, 41 commerçants, 39 managers, 37 aides ménagères et 35 ouvriers. Objectif : Pour les travailleurs, nous avons tenté d’établir le degré d’exposition aux troubles de la voix selon la profession exercée en fonction de leur représentation dans la partie francophone de la Belgique (Wallonie). Notre objectif était de cibler les travailleurs les plus à risque de consulter un spécialiste de la voix. Méthode : Nous avons estimé la proportion de ces travailleurs par profession en calculant le rapport entre leur nombre en consultation phoniatrique et leur nombre parmi les travailleurs wallons. Résultats : Les travailleurs qui consultent le plus pour un problème de voix et qui sont donc le plus à risque sont, par ordre décroissant : les chanteurs, comédiens et musiciens (3.3% ont consulté), suivis par les professeurs de musique (1.5%), les animateurs (0.45%), les entraineurs sportifs (0.29%), les psychologues (0.20%), les journalistes et standardistes (0.17%), et les enseignants (0.14). En conclusion, cette étude montre que les travailleurs qui consultent le plus en phoniatrie ne représentent pas nécessairement le groupe professionnel le plus à risque. [less ▲]

Estimated subglottic pressure (ESGP) is part of the aerodynamic measurements included in the vocal profile. It is an indication of vocal effort and can guide the therapist in his clinical approach. We aim to examine the clinical interest of the ESGP by observing its values according to voice pathology, age, gender and sound pressure level. We also examine the relationships between PSGE, DSI and VHI. Method:The study includes 418 patients (M:118/W:300). Each patient’s file consists of VLS, acoustic, aerodynamic and perceptual measures. The ESGP was collected through the Phonatory Aerodynamic System Model 6600 (KayPentax). Patients produced 3 sequences of / ipipi / at low (IL), conversational (IC) and high (IH) intensity. Patients were grouped according to the ENT’s diagnosis. Results: Patients without vocal lesions (MTD) had a significantly lower ESGP compared to patients with nodules, polyps, inflammation, edema (IL, IC), cysts (IC) or scar (IC). Patients with vocal fold atrophy had a lower ESGP than those suffering from nodules and polyps at conversational and high intensity, but were not differentiated at low intensity. Amongst patients without lesions (MTD), a positive correlation appeared between ESGP and intensity; which was not the case for patients with lesions. At high intensity, men had a significantly higher ESGP than women. At low intensity, we noted a positive correlation between the VHI scores and ESGP levels. At low and conversational intensity, we observed a negative correlation between DSI and ESGP scores. Conclusion: This study highlights the importance of considering ESGP in the vocal profile. As expected, patients with vocal pathology produce high ESGP. However, the correlations between intensity and ESGP vary depending on the patient's pathology. In addition, ESPG values allow the clinician to distinguish MTD and healthy patients and thus could help the therapist in his clinical approach. [less ▲]

Objective: One can easily recognize the musical style of a singer by listening to his/her sung performance. Several acoustical parameters of the Western operatic singing technique have been studied. However, the number of parameters could be extended and the effect of melody on these parameters remains unclear. By observing the effects of melody and technique on acoustical and musical parameters of the singing voice, this study aims at further characterizing the Western operatic singing technique. 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 show that the choice of melody had a limited impact on the acoustical and musical parameters observed, whereas a particular vocal profile appeared depending on the vocal technique employed. By examining these parameters in a theoretical model, this study highlights the relevance of vibrato rate, sound level, energy distribution, fundamental frequency of the starting note and tempo in describing the Western operatic singing technique. Conclusions: This study confirms that vocal technique affects most of the parameters examined and that the effect of melody is limited. In addition, the observation of quality and musical parameters contributes to a better understanding of the operatic singing technique. Conversely, the perturbation parameters don’t seem to take part in the characterization of operatic singing voices. Although the suggested theoretical model needs to be further developed in future research, it already generates implications for research and teaching. [less ▲]

In order to categorize sung performances as “in tune” or “out of tune”, one can measure the deviation between the performance and the musical notation. Depending on the study, a deviation of a semitone (100 cents) or a quartertone (50 cents) is considered as “out of tune”. However, these values are arbitrary and the current study aims to define perceptual thresholds of pitch accuracy in a melodic context. For this purpose, melodic sequences were manipulated, from “in tune” (deviation of 0 cent) to “out of tune” (10 to 80 cents, in 10 cents steps). In a 2x2x2 design we systematically varied the conditions of: melodies (ascending/descending target-interval), type of errors (interval or tonality deviation), and direction of the deviation (enlargement or compression). The sequences were presented to 30 non-musicians using the method of limits procedure, in a test/retest paradigm. For each condition, they were asked to specify whether the presented singing performances were “in tune” or “out of tune”. The results showed that participants were consistent in their evaluation between the test and the retest. The pitch accuracy threshold (M = 29 cents, ES = .75) was not influenced by the melody, the type of errors, and the direction of the deviation. This study highlights the ability of non-musicians to perceive small pitch deviations (less than a quartertone) in a melodic context. This finding elucidates on the concept of pitch accuracy and therefore yields the opportunity to revise objective tools for the evaluation of singer pitch accuracy. [less ▲]

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 ▲]

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.

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 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 ▲]
