The purpose of this study is to explore quantitatively the hypothesis that "resonant voice," may enhance recovery from acute laryngeal phonotrauma, based on molecular assays from human laryngeal secretions and secondarily, clinical tests.
The objective is to use the following operationalized question: Does a voicing mode shown to correspond to high-amplitude, low impact vocal cord oscillations, "resonant voice," improve the amount and time-course of recovery from acute phonotrauma, compared to vocal rest or spontaneous speech, as measured with molecular assays (primarily) and with behavioral and clinical tests (secondarily)?
