Restrictive modification is one of the most important linguistic factors in determining the phonetic realization of lexical accents in Tokyo Japanese. In this paper, acoustic analyses of read speech and perceptual experiments using synthetic stimuli were conducted to quantitatively describe the relationship between restrictive modification and the realization of accents. The results indicate the following: (1) If an MSP (a minimal syntactic phrase that comprises a content word followed or not followed by particles) has a falling-type accent, namely, if it has a lexically specified pitch fall and does not restrictively modify the subsequent MSP, the amount of the rise in the second MSP should exceed a threshold value of about 25% of that of the preceding fall (when the second MSP has a fallingtype accent) or 50% (when the second MSP has a flat-type accent, that is, when it does not have a lexically specified pitch fall), as shown in Figs. 16, 17 and 19. (2) If an MSP has a flat-type accent and does not restrictively modify the subsequent MSP, there should be a pitch valley of up to 9 semitones in depth between the two MSPs and a rise in the second MSP so that the latter has a pitch peak that is approximately 0.5 to 2 semitones lower than that of the former, as shown in Fig. 22
