Degrees of supraglottic activity may be influenced by several independent variables that commonly change during regular voice production (e.g. level of loudness, pitch, and phonatory task).
Previous studies have evaluated specific variables that may affect the degree of supraglottic tissue displacement in professional voice users.
This course is designed to provide information about the variables that influence supraglottic activity in singing and why this activity should not be necessarily considered as a sign of vocal hyperfunction.
