| Abstract(in English) | In this paper, we propose a speech/music/noise discrimination technique using image features of sonagram (a 2-dimension image, the horizontal axis of which represents time, the vertical axis of which represents frequency, and the intensity of each point in which represents power of a particular frequency at a particular time). In the proposal technique, we focus on a difference in the sonagram between each audio section. In case of speech, gentle curves are drawn on the sonagram because the peak frequency of speech changes gently. In case of music, horizontal lines are drawn on the sonagram because the peak frequency of music is stable. And in case of noise, random points are drawn on the sonagram because the peak frequency of noise is unstable. Therefore, we calculate the 2-dimension frequency of the sonagram and discriminate three kinds of audio sections using discriminant analysis. We evaluated the proposal technique by precision and error rate of discrimination. |
