Processing interactions between segmental and suprasegmental information in native speakers of English and Mandarin Chinese.

The processing interactions between segmental and suprasegmental information in native speakers of English and Mandarin Chinese were investigated in a speeded classification task. Since in Chinese, unlike in English, tones convey lexically meaningful information, native speakers of these languages may process combinations of segmental and suprasegmental information differently. Subjects heard consonant-vowel syllables varying on a consonantal (segmental) dimension and either a Mandarin Chinese or constant-pitch (non-Mandarin) suprasegmental dimension. The English listeners showed mutual integrality with the Mandarin Chinese stimuli, but not the constant-pitch stimuli. The native Chinese listeners processed these dimensions with mutual integrality for both the Mandarin Chinese and the constant-pitch stimuli. These results were interpreted in terms of the linguistic function and the structure of suprasegmental information in Chinese and English. The results suggest that the way listeners perceive speech depends on the interaction between the structure of the signal and the processing strategies of the listener.
