Background and Objectives:diseases are concerned about postoperative voice quality, there was no way to propose postoperative voice objectively. For this reason, the authors studied to synthesize predictive postoperative voice based on preoperative voice. Materials and Method:The authors evaluated 47 patients who experienced laryngeal microsurgery due to pathologic voice with benign laryngeal diseases. The voice was analysed by Computerized Speech Lab 430B. Linear Prediction and Pitch Synchronous Overlap and Add methods were used to synthesize the predictive voice. Asesments for the synthetic voice were sound
