초록

Analysis of the voice and its corresponding studies are examined from the recording of the voice through microphone and various calculation processes of the signals by using computer. Voice analyser include data acquisition and analyzing program. Since oath program uses different voice signal processing algorithm, thorough understanding of the operation is essential. In this study, analysis result of patient voice were compared by using four different voice analysis programs such as MDVP, Praat, TF32, and the program developed in this study. Pitch, jitter and shimmer were selected as comparison analysis factors. As a result, pitch, jitter and shimmer showed different result since each program uses different pitch computation algorithm.
