About

The objectives for this research are to determine the mechanisms by which specific therapy tasks improve voice in age-related dysphonia, and the conditions that limit the extent of improvement. The central hypothesis is that targeted therapy tasks will improve voice, and that severity will determine the extent of improvement.
