The current study lays the groundwork for a model of Mandarin tones based on both native speakers' and non-native speakers' perception and production. It demonstrates that there is variability in non-native speakers' tone productions and that there are differences in the perceptual boundaries in native speakers and non-native speakers.There are four experiments in this study. Experiment 1 utilizes native speakers' production data from a published speech database to explore the features of tone production by native speakers. Inter-speaker normalization is used to analyze the data.Experiment 2 synthesizes 81 tones that are carried by four sentences to measure perception by native and non-native speakers. The intra-speaker and inter-speaker normalization is used to investigate the perceptual space of T1, T2, T3, and T4. The researcher also explores the salient features distinguish native speakers' and non-native speakers' perception of the four principal tones. Experiment 3 uses both synthesized tones and natural tones that are carried by sentences to explore how pitch values of tones create overlapping areas in the perceptual map. Experiment 4 examines tone production by non-native speakers to identify the differences between native speakers' perception and non-native speakers' production; and the differences between non-native speakers' perception and their production of tones.The results of the perception and production experiments with native speakers show the perceptual boundaries and tonal categories in the perceptual space and the production space. The difference of native speakers' perception and production shows us the perceptual cue for perception. Meanwhile, the similarities of native speakers' perception and production reveal the acoustic cues, including register and contour, for tone perception and production. The results of the perception experiments with non-native speakers indicate that there are no clear boundaries, and that tone overlap in 2 the perceptual space. Register plays an important role in the perception of tones by non-native speakers. The results of non-native speaker production also show overlapping tones in the acoustic space. The non-native speaker production appears to be determined by the contour of the tones in contrast both the contour and register determine the tonal categories of native speaker. Abstract Approved ____________________________ Thesis Supervisor ____________________________ ii To my mother. iii ACKNOWLEDGMENTS I am grateful for all the supports I have received while researching and writing up this dissertation. My biggest thanks go to my advisor, Professor Richard Hurtig, who was always ready with a thoughtful response whenever I needed help and advice. His advice has been through every step of my dissertation research: the literature review and experimental design were developed through our weekly meetings; the tone synthesis and data analysis were under his supervision and conducted in the perception laboratory; and the results and discussion were completed throu...
Linguists have predominantly maintained that perception precedes production (Dinnsen 1983), an assertion also accepted by those studying second language acquisition (Flege 1995). However, an observation of acquisition of tones in Chinese as a second language suggests that American learners make different tonal mistakes in perception and production. This study explores tonal perception and production referring to the sound system of Mandarin, since a tone has a close relationship with an initial that is an onset and a final that is a rhyme within a syllable in Mandarin. The research instrument has 84 monosyllables that are representative according to the relationship among initials, finals and tones. Twenty-five American learners of Chinese in second-semester Chinese class and 11 learners of Chinese in fourth-semester Chinese class participated in this study. A two-way mixed ANOVA is the main statistical method used to analyze the acquisition data. The results reveal that tonal production is better than tonal perception. The error distribution of perception is influenced not only by tonal features, but also by initial features and final structures. For production, however, initial and final features do not influence tones. Therefore, the paper argues that tones are perceived at the phonological level and produced at the phonetic level and it takes L2 learners longer time to acquire phonological features of tones.
