Self-reported complementary data regarding feelings of voice usage included comparisons between pre and post intervention scores of the Voice Handicap Index (VHI) survey.ResultsIn this study, acoustic voice parameters measured revealed changes in vocal performance in the desired direction, as demonstrated by visual inspection and estimation of effect size of the data; changes were maintained during the follow-up phase. Examination of VHI results suggested post intervention improvement in functional and psychosocial aspects related to voice use.ConclusionsBased on the results of this study, audiovisual feedback approaches are effective in the treatment of puberphonia.
