Material and methods: This prospective study was conducted in Maulana Azad Medical college New Delhi from December 2002 to 2008. In this study 100 subjects were included comprising of all age groups and either sex. All these patients with organic voice disorder underwent speech analysis using VAUGMI speech analysis program before and after phonosurgery. Result: All the parameter of voice analysis were deranged before the treatment but after surgery all the parameters should improvement most significant change was seen in the jitter. Conclusion: After doing this study we found that the analysis of hoarse voice using various parameters of acoustic analysis like fundamental frequency, harmonics to noise ratio, jitter, shimmer, S/z ratio helped us in identifying the degree of hoarseness and the severity related to it. Some parameters like jitter and shimmer were able to detect the component of hoarseness in perceptually normal voice and thus patient was helped by doing surgery and voice therapy at the appropriate time.
