DESCRIPTION: This program of research seeks to understand how listeners recognize phonological variants of spoken words as the word intended by the talker. As a first step in achieving this goal, research will focus on developing a clear and accurate description of phonological variation by collecting, transcribing, and analyzing a 100, 000-word corpus of conversational speech. Two types of analyses will be performed. Phonological analyses will center on developing a picture of phonological variation that the recognition system encounters on a regular basis, calculating the forms of variation, their frequency, and the contexts in which they occur. Acoustic analyses of variants will be carried out to develop a detailed description of variation that is tightly linked to the speech signal itself. The results from both lines of work should provide a solid foundation on which the recognition of phonological variants can be profitably studied in future work.

描述：这项研究计划旨在了解听众如何 将口语单词的语音变体识别为 健谈的人作为实现这一目标的第一步，研究将侧重于 发展一个清晰和准确的描述语音变化， 收集、转录和分析了一个10万字的语料库， 会话式的演讲将进行两种类型的分析。语音 分析将集中在发展一个语音变化的图片， 识别系统定期遇到，计算的形式 变化，其频率，以及它们发生的背景。声学 将对变体进行分析，以详细描述 与语音信号本身紧密相关的变化。的结果 这两方面的工作应该提供一个坚实的基础上，承认 在今后的工作中，语音变体的研究可以是有益的。
