Voice function and voice disorders in adults
Project group leader
The area includes research on the voice in patients with different types of voice disorders such as functional, organic, neurological, and hormonal. Several projects deal with the development of methods to better document and quantify various aspects of voice function, others on the development of treatment methods. Methods for assessing voice function include audio perceptual, acoustic, and aerodynamic analysis of sound recordings made in a standardized recording environment, as well as analyzes of long-term measurements of voice use from everyday situations. Development of questionnaires and patient-reported measures adopted to different patient populations are ongoing. The methods are necessary to be able to evaluate different treatment interventions such as voice therapy, surgery on the vocal folds, and hormone therapy.
