感知中心（或“p-中心”）对应于音节或单词出现的感知时刻，并且在语音节奏的感知中至关重要。一个节拍器对齐任务被用来调查如何语气和prenasalization-两个因素，影响语音的时间，也相互作用的声学影响的P-中心位置在地中海mba，一个Grassfields班图语。普通CV的话，低音调被发现有P-中心，后来（远离辅音释放和接近元音发作）比那些轴承高音调，但观察到的效果是不存在的prenasalized的话。我们把这种差异归因于在预鼻音化形式中音调降低和斜率变平的影响。虽然prenasalization一般导致较早的p-中心（镜像效应发现在其他语言中的发病集群），形式与形态衍生prenasal发病表现得更像普通的CV形式，这表明鼻前缀不有助于p-中心的时间。我们的研究结果派生prasal序列平行类似的发音结果的语言与单发病协调，辅音“集群”实际上表现为单独的时间单位。
Perceptual centers (or ‘p-centers’) correspond to the perceptual moment of occurrence of a syllable or word, and are crucial in the perception of speech rhythm. A metronome alignment task was used to investigate how tone and prenasalization—two elements which affect speech timing and which also interact acoustically—influenced p-center location in Medʉmba, a Grassfields Bantu language. Plain CV words bearing low tones were found to have p-centers which were later (farther from consonant releases and closer to vowel onsets) than those bearing high tones, but the observed effect was not present in prenasalized words. We attribute this difference to the effects of tone depression and slope leveling in prenasalized forms. While prenasalization generally led to earlier p-centers (mirroring effects found for onset clusters in other languages), forms with morphologically-derived prenasal onsets behaved more like plain CV forms, suggesting that nasal prefixes do not contribute to p-center timing. Our findings for derived prenasal sequences parallel similar articulatory findings for languages with simplex onset coordination, where consonant ‘clusters’ actually behave as separate timing units.
