项目摘要

Recent research has shown that many words traditionally assumed to be homophones are not pronounced the same but exhibit systematic phonetic differences. This finding calls into question standard assumptions of established models of phonological representation and speech production. The proposed project aims at contributing to this emergent line of research by analyzing the acoustic realization of alleged homophones that have uses in more than one word class. More specifically, the aim is to compare the noun realization to the verb realization of noun-verb homophones, such as profit or notice. Since such noun-verb pairs are very frequent in English, this project targets a widespread characteristic of the English lexicon. From previous research it is known that the noun and verb pronunciation of these forms differ due to different sentence positions they occur in, resulting in nouns being more frequently subject to lengthening effects. Beyond this contextual influence, there is initial evidence of further variation between noun and verb realization; however, this has not been systematically explored yet. The first aim of this project is to empirically investigate these context-independent differences in acoustic realization, using speech data from corpora and from experimental elicitation. The second aim of the project is to test whether language users use phonetic detail of noun-verb homophones as a cue to word class; this assumption will be tested in perception experiments. The findings from both the production and the perception tasks will contribute to our understanding of the representation of phonetic detail for a substantial share of the English lexicon.

最近的研究表明，许多传统上被认为是同音异义词的单词并不发音相同，而是表现出系统的语音差异。这一发现质疑标准假设的语音表征和语音生产的既定模型。拟议的项目旨在通过分析在多个词类中使用的所谓同音异义词的声学实现，为这一新兴的研究领域做出贡献。更具体地说，目的是比较名词实现的动词实现的名动同音，如利润或通知。由于这种名动搭配在英语中非常常见，因此本项目针对英语词汇的一个普遍特征。从以前的研究中可以看出，这些形式的名词和动词的发音由于它们出现在不同的句子位置而不同，导致名词更经常受到延长效应的影响。除了这种语境的影响，有初步的证据进一步变化之间的名词和动词的实现，但是，这还没有被系统地探讨。这个项目的第一个目的是实证研究这些上下文无关的声学实现的差异，使用语料库和实验启发的语音数据。本研究的第二个目的是检验语言使用者是否使用名动同音异义词的语音细节作为词类的线索，这一假设将在知觉实验中得到检验。从生产和感知任务的结果将有助于我们了解语音细节的表征相当大的份额的英语词汇。
