Abstract

There is a large body of work in phonetics and phonology demonstrating sources and structure of acoustic variability, showing that variability in speech production is not random. This paper examines the question of how variability itself varies across languages and speakers, arguing that differences in extent of variability are also systematic. A classic hypothesis from Dispersion Theory (Lindblom, 1986) posits a relationship between extent of variability and phoneme inventory size, but this has been shown to be inadequate for predicting differences in phonetic variability. I propose an alternative hypothesis, Contrast-Dependent Variation, which considers cue weight of individual phonetic dimensions rather than size of phonemic inventories. This is applied to a case study of Hindi and American English stops and correctly predicts more variability in English stop closure voicing relative to Hindi, but similar amounts of lag time variability in both languages. In addition to these group-level between- language differences, the results demonstrate how patterns of individual speaker differences are language-specific and conditioned by differences in phonological contrast implementation.

对比实施影响语音变异性：以印地语和英语停顿为例

在语音和音韵学领域有大量的工作证明了声学变异的来源和结构，表明语音产生中的变异不是随机的。本文研究了变异性本身如何在不同语言和使用者之间变化的问题，认为变异性程度的差异也是系统性的。色散理论（Lindblom，1986）中的一个经典假设假设了变异程度和音素库存大小之间的关系，但这已被证明不足以预测语音变异的差异。我提出了另一种假设，对比度相关变异，它考虑了单个语音维度的线索权重，而不是音素清单的大小。这被应用于印地语和美式英语停顿的案例研究，并正确地预测了与印地语相比，英语停顿闭包发音的可变性更大，但两种语言的滞后时间可变性相似。除了这些群体层面的语言间差异外，研究结果还表明，个体说话者差异的模式是特定于语言的，并受到语音对比实施差异的制约。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
