Summary

Singers are over-represented in phoniatric consultation; they present increased risk of developing voice disorders. They represent a specific population among phoniatric patients (specific singing-voice complaints, increased sensitivity to voice). Singing-voice disorder is called dysodia in the same way as dysphonia, which refers to speaking-voice disorders. The diagnosis of dysodia is made after a laryngeal examination and a voice assessment to identify patient's speech and singing difficulties. Most studies on prevalence of voice disorders in singers come from the American continent. Very few descriptions of this population have been made in France.

Voice assessment of dysodic singers includes aerodynamic voice measurements. The use of aerodynamic measurements for the diagnosis of voice pathologies is now widely demonstrated. These parameters include measurements of estimated subglottal pressure (ESGP), phonation threshold pressure (PTP) (minimum pressure to initiate a sound) and oral airflow (OAF). They depend on the level of training of singers and the type of vocal dysfunction. Aerodynamic behaviours of dysodic singers have not yet been described, although they can help to better identify the singer's vocal difficulties and could be essential parameters for targeting more precisely rehabilitation exercises proposed in voice therapy.

This study aims to describe the characteristics of a French population of singers consulting in phoniatrics and their aerodynamic behaviours. Do the singers' aerodynamic parameters (pressure, flow) reflect the dysfunctions in singing voice? Based on results of the literature on speaking and singing non-pathological voice, the investigators hypothesize that during voice assessment, ESGP values will be increased and OAF ones will be decreased over the entire vocal range of the singer in case of voice pathology.
