MDVP와 Praat, Dr. Speech간의 음향학적 측정치에 관한 상관연구 = A Correlation Study among Acoustic Parameters of MDVP, Praat, and Dr. Speech

다국어 초록 (Multilingual Abstract)

The purpose of this study was to conduct a correlational analysis among Fo, Jitter, Shimmer, and NHR(HNR), and NNE estimated by three speech analysis softwares, MDVP, Praat and Dr, Speech. Thirty females and 15 males with normal voice participated in the study. We used Sound Forge 6.0 to record their voice. MDVP, Praat and Dr. Speech were used to measure the acoustic parameters. The Pearson correlation coefficient was determined through a statistical analysis. The results came out as follows:
Firstly, there was a strong correlation between Fo and Shimmer of both instruments. However, there was no correlation between Jitter of both instruments. Secondly, Shimmer showed a stronger correlation with HNR, NHR, and NNE than Jitter. Therefore, Shimmer was considered to be more useful and sensitive parameter to identify dysphonic voice compared to Jitter.
