Metathesis: Database and Theory Development Project

9809732休谟这个项目的重点是复分解，声音似乎彼此转换位置的过程。因此，在一串声音中，我们期望两个声音的线性排序是...... xy...我们却发现yx.虽然不像同化或语音删除这样的过程那么常见，但规则易位仍然是跨语言的共时系统中的规则语音过程，因此反对通常认为易位是零星和不规则的观点。此外，初步研究表明，考虑到知觉的容易，一个统一的解释背后的动机广泛的复分解是可能的。然而，基本的知识是缺乏有关的全方位的复分解，可能在共时系统中，复分解适用的条件下，是否感知因素能够解释所有的情况下，以及如何复分解与其他过程相互作用影响的声音结构。这些信息对复分解预测理论的发展至关重要。这也是至关重要的语音理论的进步，因为没有一个清晰的理解，在人类语言中可能的基本语音过程，发展一个解释性的理论的声音系统是不可能的。因此，这个项目的目标是双重的：第一，编译一个全面的数据库，证明易位的情况下;第二，发展预测和约束理论的易位。

9809732HumeThe focus of this project is on metathesis, the process whereby sounds appear to switch positions with one another. Thus, in a string of sounds where we would expect the linear ordering of two sounds to be ...xy..., we find instead ...yx.... While less common than processes such as assimilation or sound deletion, regular metathesis nonetheless occurs as a regular phonological process in synchronic systems cross-linguistically, thus countering the commonly-held view of metathesis as sporadic and irregular. Moreover, preliminary research suggests that by taking into account considerations of perceptual ease, a unified account of the motivation behind a wide range of metatheses is possible. However, basic knowledge is lacking concerning the full range of metatheses that are possible in synchronic systems, under what conditions metathesis applies, whether perceptual factors are able to account for all cases, and how metathesis interacts with other processes affecting sound structure. This information is critical to the development of a predictive theory of metathesis. It is also of crucial importance for the advancement of phonological theory since without a clear understanding of the fundamental phonological processes possible in human language, developing an explanatory theory of sound systems is impossible. The goal of this project is thus two-fold: first, to compile a comprehensive database of attested metathesis cases; and second, to develop a predictive and constrained theory of metathesis.
