The moment of perceptive occurrence of a sound event is defined as “perceptual center” (P-center). So far, P-center locations have been measured experimentally in English utterances and in sounds of instrumentals, and researchers have tried to make some P-center models. However, the valid predictive model has not been established, and P-centers have not been verified for the Japanese L1 speakers. On the other hand, the identification of the P-center locations in the syllables is indispensable to grasp language rhythms directly. In learning the Japanese language, the acquisition of special moras is important, and the P-center locations seem effective indicators of direct and objective rhythm evaluation. In this study, approximate P-center locations of ordinary syllables in the Japanese language were identified by using looped repetitions of reference-test sounds and forced choices on the part of ten Japanese L1 speakers. Acoustic markers visible with spectrogram were set as the choices. Analyzed with acoustic information connected with articulatory timing, a competition of “an oral cavity event onset marker” and “a vowel onset marker” is found in a P-center of CV syllables. In precedent studies, the P-center of the syllable onset location was denied, and most of oral cavity event markers are located there in silent obstruent consonant. Therefore, it is thought that “vowel onset marker” is usually chosen predominantly, but “oral cavity event marker” can be chosen in the experimental environment. In addition, at the syllables with the “flip” consonant (which has a complicated articulation), the oral cavity event marker is chosen overwhelmingly. Therefore, it is suggested that the choices may vary for different phonemes. However, the P-center location of V syllables was not identified sufficiently in this study.
