A series of studies were conducted on the prosodic features of the English spoken by Japanese to find out which features (i.e. the duration of each sound, the fundamental frequency change and the intensity change) should be altered and how they should be changed in order for their English to be judged more English-like. Various combinations of three prosodic features, in an English sentence uttered by a Japanese speaker in a typically Japanese fashion, were replaced with the same combinations of the prosodic features of the same English sentence read by an Englishman. Through a listening test it was found that the duration component and the fundamental frequency change played far more important roles than the intensity component in the acceptability judgment.
