Résumé
The purpose of this study is to highlight a difference between the aerodynamic parameters showed in dysodic singers compared to non-dysodic singers during the vocal assessment. Thereby, we wish speech therapy to achieve a deeper development of these parameters in order to find more relevant and efficient therapies to sort out these problems. Method : This retrospective study consists in the analysis of files of female singers, of all training levels, who came to consult the phoniatrist Dr Amy de la Bretèque, at the CHU Gui de Chauliac between 2016 and 2018. Measurements of subglottic pressure, phonatory pressure threshold and oral airflow were taken on an aerodynamic task proposed during the vocal assessment. Anamnestic data were also collected through the records to know in particular the diagnoses of laryngopathies made. Results : We only obtained significant differences in statistical tests for the pressure parameters at the fundamental frequency. However, the qualitative analysis shows the dysodic pressures clearly tend to increase. It also shows the oral airflows in the dysodic subjects also tend to rise up although it is less obvious than for the pressures. Conclusion : The results of this study are consistent with an increase in pressure and flow parameters in dysodic subjects compared to non-dysodic subjects. Future research on the relationship between aerodynamic dysfunction and singing voice disorders would therefore be relevant. The final goal is therefore to ensure that dysodic singers can benefit from a specific vocal assessment and from a more relevant and efficient therapy when they are offered rehabilitation
