Based on the type and cause of the voice disorders, we carry out the corresponding voice therapy strategies. The datas are collected before therapy (A) and during therapy (B). Use A-B designed single subject experiment and T-test for significance statistical test in this study. Voice therapy strategies have been proved effectively for functional voice disorder patient.Because of the wideness of the research on voice therapy strategies, this dissertation only acquired staged achievement.
