Optimizing Aerodynamic Vocal Parameters by Varying Supraglottic Pressure Using “Controlled Supraglottic Pressure Phonation” in Healthy Subjects

Higher supraglottic pressure levels will improve ease of phonation, but the treatment discomfort needs to be considered as well, yielding an optimal supraglottic pressure range of 4-6 cmH2O. "Controlled supraglottic pressure phonation" serves as an alternative to straw phonation that may produce additional benefits.
