Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in VHI-10 Score After 4 Sessions of Voice Therapy

    VHI-10 is a 10 item, self reported, voice related outcome related to an individual's perception of their vocal quality and how it impacts their life. (Voice Handicap Index) Scale scores range from 0-40 where higher scores correspond to a worse vocal quality.

    Baseline and approximately 6-8 weeks later; after completion of voice therapy

Secondary Outcomes (5)

  • Change From Baseline in Cepstral Peak Prominence (dB)

    Baseline and approximately 6-8 weeks later; after completion of voice therapy

  • Change From Baseline in Cepstral Spectral Index of Dysphonia (CSID--a Multivariate Estimate of Dysphonia Severity)

    Baseline and approximately 6-8 weeks later; after completion of voice therapy

  • Change From Baseline in Mean Airflow in Milliliters (ml) During Reading of Standardized Paragraph

    Baseline and approximately 6-8 weeks later; after completion of voice therapy

  • Change From Baseline in Mean Vocal Intensity (dB)

    Baseline and approximately 6-8 weeks later; after completion of voice therapy

  • Change in the Number of Breaths Taken During Reading of Standardized Paragraph

    Baseline to post treatment
