Voice problems can be triggered by both vocal misuse and overuse. While misuse is caused by inappropriate vocal actions, overuse results from greater vocal loading than the individual is able to recover from. Vocal load depends primarily on the quantity of phonation in terms of duration, fundamental frequency and sound pressure of the voice. Portable load quantification systems have been available for several years. These dosimeters allow the objective description of vocal behavior in real situations for a prolonged duration. They are primarily used by voice professionals – people who need their voices for their work – such as teachers and singers. Voice dosimetry makes it possible to identify risky vocal behaviors and situations promoting dysphonia, in an ecological context. The objective of research using these tools is to suggest guidelines for the prevention, evaluation and treatment of dysphonia, mainly in people who use their voices a lot. In addition, this research attempts to set standards for daily voice use for different groups of individuals. [less ▲]

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.

Objective. Research has paid increased attention to occupational voice disorders. This study describes the occupational status of patients examined in the Department of Otorhinolaryngology at Liège University Hospital (Belgium) from 2009 to 2013. Study design. Retrospective study. Methods. The sex, age, diagnosis and occupational status were identified for 1,079 patients who were examined for a voice problem (754 women and 325 men; ages 4 to 93). The diagnosis was established using videolaryngostroboscopy. For patients who were employed, we identified (1) the numerically most frequent professionals, and (2) the professionals most at risk of consulting for their voice, based on the distribution of these professions among all workers living in French-speaking Belgium. Results. 11% of patients were unemployed, 15% were students, 20% were retired, and 54% were workers. In decreasing order of frequency, the most commonly seen professionals were teachers, office workers, artists (singers, actors, and musicians), storekeepers and marketing representatives, managers, domestic workers, and laborers. Regarding their distribution in the working population, the workers at greatest risk of consulting were artists, music teachers, counselors, sports coaches, psychologists, switchboard operators, journalists, and teachers. Nodules are the most common pathologies, encountered in 16.8% of the workers and 42.8% of the students who consulted the Department of Otorhinolaryngology for dysphonia. Conclusion. Prevention is needed both for the professions that seek medical help in the largest numbers (teachers) and for those that are at highest risk of consulting (artistic professions). In addition, teachers must be informed of the need to seek help as soon as voice problems appear. Level of evidence: 2b [less ▲]

Background: Estimated subglottic pressure (ESGP) is part of the aerodynamic measurements included in the vocal profile. It is an indication of vocal effort. Speyer reports an improvement of the ESGP score after voice treatment. Nevertheless, few studies used ESGP to evaluate voice efficiency treatment. Objectives: The purpose is to examine the ESGP twice, at the first (T1) and the last consultation (T2) . We observe the ESGP values according to voice pathology. We also examine the relationships between ESGP, SPL(Sound pressure level) and DSI (Discorder severity index) . Method: The study includes 130 patients (M:31/W:99), which suffer from 4 different pathologies as immobility (N: 54), oedema (N:23), nodules (N:24) and polyp (N:29). 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. We compare our values to those of Zraick et al (2012) which studied ESGP on a healthy group. Results: At T2, for the all patients, at minimum and conversational intensity the ESGP scores decrease singificantly, even if those scores were higher than for the healthy group. We observe a negative correlation between ESGP and SPL at low and conversational intensity. At T1, the higher is the ESGP score, the lower is the SPL score. At T2, the higher is the ESGP score, the higher is the SPL score. At T1, a negative correlation is observed between ESGP and DSI for 2 groups of patients (immobility and polyp) only at minimum intensity. The higher is the ESGP, the lower is SPL. At T2, only for the group immobility, the negative correlation persists. Conclusion: This study highlights the importance of considering the ESGP as a parameter of efficiency. High ESGP is mainly connected with patients who suffer from pathology. The patient who suffer from immobility seems to present a specific profile which could help the clinician to better understand their vocal behavior. Recommendation: This study highlights the pertinence of considering the ESGP as a parameter of vocal treatment efficiency. [less ▲]

Parlée ou chantée, notre voix révèle qui nous sommes. Elle participe à notre identité et véhicule nos émotions (ref. Revis. J). Dans cet exposé, nous présenterons la voix du point de vue du genre. En effet, l’Unité Logopédie de la Voix (www.logopedie-voix.be) s’intéresse entre autres à la féminisation vocale chez les personnes transidentitaires, en processus de changement de genre. Ces personnes ne s’identifiant pas au sexe et au genre qui leur ont été attribués à la naissance, elles éprouvent un désir profond de vivre comme une personne du sexe opposé à leur sexe biologique. Lors du processus de transition où ont lieu les transformations nécessaires au changement de genre, la logopédie a pour but d’améliorer la cohérence entre l’apparence de la personne et sa voix. Ainsi, notre recherche se focalise sur ce qui distingue la voix féminine de la voix masculine. Nous visons à développer des stratégies de féminisation vocale, portant sur des paramètres tels que la fréquence fondamentale de la voix (grave ou aigüe), les contours intonatifs, le niveau d’amplitude de certains formants, le débit de parole, son rythme, ou encore le vocabulaire choisi. Féminiser une voix, c’est chercher à comprendre ce qui permet d’en identifier le genre, mais également participer à la construction de l’identité de la personne à part entière. [less ▲]

Objectif: Notre but est d'analyser la pression sous-glottique estimée (PSGE) en fonction de la pathologie vocale, du genre et du niveau de pression sonore. Nous observons également les corrélations entre la PSGE, le Voice Handicap Index (VHI) et le Dysphonia Severity Index (DSI). Méthode: 418 patients (118 H, 300 F) ont réalisé un bilan vocal (VLS, mesures acoustiques, aérodynamiques, VHI). La PSGE est collectée à l’aide du Phonatory Aerodynamic System Model 6600 (KayPentax). Les patients ont produit 3 séries de /ipipi/ à 3 niveaux de pressions sonores (conversationnel, faible et fort). Résultats: A intensité forte, les hommes ont un niveau de PSGE supérieur à celui des femmes. A intensité faible, le groupe « atrophie » montre des scores plus faibles que le groupe « nodules » et à intensité forte plus faibles que le groupe « polype ». A intensité conversationnelle, le groupe « examen normal » montre des scores plus faibles que les groupes « nodules », « polypes » et « œdème de Reinke ». A intensité faible, la même différence est observée avec en plus les groupes « kystes » et « cicatrices ». Nous observons une corrélation positive entre la PSGE et le VHI à intensité faible et négative à intensité forte. A intensité conversationnelle et faible, nous observons une corrélation négative entre le DSI et la PSGE. Quel que soit le niveau d’intensité, nous n’observons pas de corrélation pour le groupe « kyste ». Conclusion: Cette étude met en évidence l’intérêt de la PSGE. Une PSGE élevée est principalement observée chez les patients avec lésion sur le plan glottique. La corrélation entre PSGE et niveau de pression sonore varie en fonction de la pathologie. La mesure de PSGE peut aider le clinicien à mieux comprendre le comportement vocal du patient en lien avec sa pathologie. [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 ▲]

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 ▲]

Reliability and Validity of the "Voice Handicap Index (VHI) Adapted to the Singing Voice" in German. Background : The Voice Handicap Index (i.e., VHI) is one of the most reliable standardized self-evaluation assessments in diagnosis of voice disorders. That tool is the most used in daily clinic,. In 2007, the VHI was adapted to the singing population, called"VHI adapté aux chanteurs". The aim of our study was to investigate the reliability and validity of the German version of the VHI adapted to the singing voice. Materials and Methods: 113 German singers (41 males and 72 females) with diverse singing styles and profession were included in the study. They were divided into 2 groups : a test-group (n=20) with self-perceived vocal complaints and a control-group (n=93) without vocal complaints. Statistical analysis to measure the reliability and validity was conducted with the Cronbach's alpha (i.e., cron.a), independant t-test and receiver operating characteristics as well likelihood ratio, respectively. Results : Reliability was confirmed by acceptable Cron. a (0,713-0,850) for each of the sub-scales and total score. The validity between the 2 groups showed high signifiant differences for each of the sub-scales and total score by which the test-group indicated higher scores than the control-group. Only the construct validity revealed no clear results. Conclusion : The VHI adapted to the singing voice is suited as reliable and valid standardizing evaluation tool, but the diagnostic accuracy has to be investigated again because of too high inaccuracy in the interpretation of the outcome of the present data.

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 ▲]
