也許pitch這裏用得不對,我最近瀏覽一本關於voice & articulation的書,分別講到pitch和intonation,intonation 他說是:As you talk, your voice moves from sound to sound with an almost continuous rise and fall in pitch, touching peaks, plateaus, and valleys. The overall pattern of pitch changes in phrases and sentences is described as intonation, speech melody, or pitch contour. 可能還是象你說的,是語調的問題,可能是從高到低過度不夠平滑?不知道,bill和京北來談談?
現在看得多了,覺得俺廚師是從各處抄來的,哈哈。
