Preliminary Study 2 to Test the Effects of Ambulatory Voice Biofeedback

This study will use a single subject design to determine if adding ambulatory voice biofeedback to conventional voice therapy can result in faster carryover (generalization) of new vocal behaviors established during voice therapy to daily life. Here, ambulatory voice biofeedback will be based on objective measures that have subject-specific sensitivity to vocal hyperfunction. Hypothesis: The ambulatory voice biofeedback week (week 2) will result in higher generalization percentages when compared to baseline and the week prior to the initiation of biofeedback (week 1). This effect will be retained when the biofeedback is removed (week 3), thus it will be different than baseline and week 1, but not different than week 2.
