[Vocal and behavioral adaptations of program sellers in work situation].

Abstract

Are program sellers at the Parisian Operas at risk of developing vocal problems? What are the adaptations they use to be heard and understood in this loud environment? Six program sellers were recorded and observed at work. The methodology applied included a questionnaire, acoustic analysis of the records, a videolaryngostroboscopic examination, analysis of objective and subjective measures of vocal function. The results confirmed the existence of voice risk factors and symptoms of vocal fatigue that may justify a preventive intervention. The adaptations that program sellers carry out follow the characteristics of what is called "Lombard Speech". In addition, announces reveal common and individual specificities such as prosodic and acoustic types.
