Abstract

As a suprasegmental concept, stress is a phonetic means that represents stress, emphasis and focus in semantics. It is functional within specific linguistic systems, for example, emphasis, focusing, etc. and often varies widely in its systematization from language to language. Uygur language is a stress language, and sometimes the movement of the stress distinguishes the meaning of the word, but together with intonation and rhythm, plays an important prosodic function. Studies on Uygur word-stress have theoretical as well as practical significance. Theoretically, it can fulfill and promote the development of Uygur stress theories; it can provide suggestions on Mandarin word-stress studies. Practically, it can promote the naturalness of synthesized speech and the development of speech engineering; it can provide empirical support to stress studies in most of the world languages which regarded that pitch plays the primary role in the determination of stress; and it can promote the development of the bilingualism activities in Xinjiang Uygur Autonomous Region.This paper chose Xinjiang Uygur news broadcasting speech as the research material. By acoustic experimental analyses of the three acoustic parameters of stress——intensity, pitch and duration, this paper attempts to find out the acoustic features and stress patterns of disyllable and trisyllable word-stress in connected speech. The experiments consist of two parts, namely, the acoustic experiment on Uygur disyllable word-stress and the acoustic experiment on Uygur trisyllable word-stress. Considering the influence of intonation on word-stress in sentence final, each acoustic experiment is subdivided into two parts, that is, the acoustic experiment on non-sentence-final word-stress and the acoustic experiment on sentence-final word-stress.This paper intends to investigate the following questions:1) what are the acoustic features and stress patterns of disyllable word-stress in Xinjiang Uygur news broadcasting speech? 2) What are the acoustic features and stress patterns of trisyllable word-stress in Xinjiang Uygur news broadcasting speech?The results of the acoustic experiments on the disyllable word-stress in Xinjiang Uygur news broadcasting speech showed:intensity and duration are not significant in the determination of Uygur disyllable word-stress; instead, pitch plays the primary role. The stress patterns are that the stress falls on the second syllable and it rises from the first syllable to the second syllable with a gradually terminal leveling. And the intonation influences the disyllable word-stress patterns.The results of the acoustic experiments on the trisyllable word-stress in Xinjiang Uygur news broadcasting speech indicated:intensity and duration are not significant in the determination of Uygur trisyllable word-stress; instead, pitch plays the primary role. The stress patterns are that the stress falls on the third syllable and it rises from the first syllable to the third syllable with a slightly terminal falling. And the intonation influences the trisyllable word-stress patterns.
