This study aims to discuss pitch slope on Korean intonation curve in spontaneous speech data. For this study, 656utterances were taken in the spoken corpus and used ‘close-copy stylization’. And then the physical feature of pitchmovements was extracted for the study. The pitch slope was calculated on the basis of time and pitch range in eachutterance. As a result, the average and distribution of pitch slope is similar between men and women in the range of thepitch movement except for essential differences. The slope of pitch movement confirms that there are no differences betweenmen and women. Pitch slope on a scale of -10 to 10 is 90% of the entire pitch slope; pitch slope that moves by time scalewithout curve is 33.1%; pitch slope that moves half of the pitch bandwidth during the average time for pitch movement is23.4%; pitch slope that moves 100% of pitch bandwidth during a half of the average time for pitch movement is 10.4%. Those results imply the possibility of standardization methods of Korean intonation by pitch slope.
