Workshop on Syllable Structure and Gesture Timing, Columbus,Ohio, September 16-19, 1998

语音方面的语言话语传统上被表示为一个连接的线性字符串的音素段。从20世纪50年代初Jakobson、Fant和Halle的研究开始，区别性特征的概念被引入作为音位学描述的最小单位，根据这一概念，音位是一个由语音定义的双值特征的同时束。在这一概念中，音素是具有时间整合性的最小语音单位。在声学信号中观察到的频谱不连续性在很大程度上支持了完整音素段的识别，特别是语音的开始和偏移沿着发音的内爆和塞音的爆发。然而，从一个音素到下一个音素的过渡通常在语音信号中表示为连续平滑的频谱变化，没有明显的不连续性。一个严重的挑战，流行的音素连接和协同发音理论来自发音数据，主要是由于x射线微生物研究。随着发音手势的时间细节变得可用，很明显，表达给定音素的发音手势的连续性概念不能维持。 从音系学的角度来看，已经有一个稳定的知识进步，从线性生成理论的语音表示，发音排序和分割的问题是相当简单的，目前的非线性表示，段和功能之间的映射是相当宽松的，高度清晰的超音段结构已被假定。目前的非线性表征模型，允许单个“段”承担多个值的一个给定的功能，并相当自由地允许一个单一的功能与许多“段”相关联的一个后果，是一个可以有意义的问题的存在的离散的“段”作为一个正式的对象。事实上，特征几何的理论并没有明确地表示“段”的概念，并且有人认为传统的段概念并不对应于当前模型中的任何特定节点或表示级别。非线性模型越来越倾向于假定复杂但内部永恒的单个“片段”，而不是片段的集群。例如，对于汉语来说，李明博已经提出，根本不存在起始辅音群，并且这种明显的序列是单个的次级发音片段（（k）inter alii）。 这个研讨会的目标是集中在一个特定的领域，这是中央的理论问题的代表性，并寻求评估该领域的竞争理论，通过寻找有关的问题，音节，和'段'作为一个音系结构。关于音段及其排序存在的广泛的理论观点使得很难测试关于可能的辅音群的经验性主张。该研讨会将聚集相关领域的主要领导人，为考虑解决这些问题的不同方法的最新讨论创造一个论坛。

Linguistic utterances in their phonological aspect are traditionally represented as a con catenated linear string of phonemic segments. Beginning with research by Jakobson, Fant and Halle in the early 1950's, the concept of the distinctive feature was introduced as the minimal unit of phonological description, according to which a phoneme is a simultaneous bundle of bi narily valued phonetically defined features. In that conception, the phoneme is the minimal pho nological unit with temporal integration. The identification of the integral phonemic segment was largely supported by spectrographic discontinuities as observed in acoustic signals, in particular voice onset and offset along with articulatory implosions and explosion of stop consonants. However, the transition from one phoneme to the next is often represented in the speech signal as a continuous smooth spectral change with no apparent discontinuity. A serious challenge to the prevailing phoneme concatenation and coarticulation theory derives from articulatory data largely due to x ray microbe studies. As temporal details of articulatory gestures became avail able,.it was clear that the concept of simultaneity of articulatory gestures which manifest a given phoneme could not be maintained. From the phonological perspective, there has been a steady intellectual progression from the linear generative theory of phonological representation where issues of articulatory ordering and segmentation were quite simple, to current nonlinear representations where the mapping between segments and features is quite relaxed, and highly articulated suprasegmental structures have been often assumed. A consequence of current nonlinear representational models, which allow single 'segments' to bear multiple values of a given feature, and which quite freely allow a single feature to be associated with many 'segments', is that one can meaningfully question the existence of the discrete 'segment' as a formal object. Indeed, the theory of feature geometry does not explicitly represent the notion of 'segment', and it has been argued that the traditional notion of segment does not correspond to any specific node or level of representation in current models. Nonlinear models have increasingly tended towards positing complex but internally timeless single 'segments' in place of clusters of segments. For example, it has been proposed by Duanmu for Chinese that there are no onset consonant clusters at all, and that such apparent se quences are single secondarily articulated segments ((k) inter alii). The goal of this workshop is to focus on a particular domain which is central to the theo retical issues of representation, and seeks to evaluate competing theories of that domain, by looking at issues relating to the syllable, and to the 'segment' as a phonological construct. The wide range of theoretical perspectives which exists regarding segments and their ordering renders it difficult to test empirical claims about possible consonant clusters. This workshop will assemble major leaders in relevant areas, to create a forum for up to date dis cussion considering different approaches to these problems.
