Efficacy of a Semi-occluded Mask in the Treatment of Patients With Voice Disorders

Completed · Not applicable

Conditions studied: Voice and Resonance Disorders, Vocal Fold Polyp, Vocal Cord Cyst, Vocal Cord Polyp, Atrophy of Vocal Cord

In brief

Current semi-occluded vocal tract therapies limit the type of vocalizations that can be produced to single vowels, which does not promote learning of the healthy voice behavior in connected speech or generalization to conversation. However, recent preliminary results using a semi-occluded mask indicate that the use of certain mask port diameters may allow for natural speech production while increasing supraglottal pressure and impedance, and thereby result in elicitation of voice with increased efficiency. In addition, the use of a semi-occluded mask provides the possibility for a better transition from phonating single phonemes in therapy to training the target therapy techniques in connected speech.
