Coarticulation effects of contour tones in second language Chinese

Abstract This study tests for evidence of tonal coarticulation effects, especially anticipatory effects, in production of non-native Chinese contour tones. Eighty second language learners of Chinese and ten native speakers participated in a main experiment and two supplementary experiments in which they produced both real and pseudo disyllabic words. Findings indicate that anticipatory coarticulation is relevant in L2 contour tone production. L2 speakers’ Tone 2 and to some extent Tone 4 tend to be less intelligible to native listeners when followed by tones starting with a high onset (Tone 1 or Tone 4) due to anticipatory coarticulation. Some similar and different tonal coarticulation effects between native Chinese speakers and second language learners of Chinese are also noted in the paper based on the experiment results. This study argues that a ‘universal’ coarticulatory constraint plays a role in shaping second language Chinese tone phonology.
