Clinical Trial Summary

The purpose of the study is to evaluate the new Blom-Singer SpeakFree disposable hands free valve heat and moisture exchanger (HME). The investigators will compare the SpeakFree to other modalities of stomal occlusion (digital occlusion and digital depression of an HME) for patients who communicate with a voice prosthesis as determined by patient preference and satisfaction. In addition, the investigators will compare the SpeakFree to other modalities of stomal occlusion as determined by objective measures of speech and voice parameters (maximum phonation time, syllables per breath, minimum/maximum phonation pressures, and a clinician rating of voice quality using a visual analog scale).
