Study Summary
The main purpose of this study is to investigate voice production, speech intelligibility and routine physiologic parameters associated with the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves. Additionally, the purpose of this study is to investigate the effects (if any) associated with the Blom low profile voice inner cannula and the Passy-Muir one-way tracheotomy tube speaking valves on swallowing behavior and biomechanical movement of the hyolaryngeal complex during routine diagnostic modified barium swallowing evaluations.
Primary Outcome
Maximum duration of voicing (seconds) will be obtained, after instructing the patient to say the vowel /a/ as long as possible timed with a stopwatch.
