RECOGNIZING PHONOLOGICAL VARIANTS OF SPOKEN WORDS

描述：这个研究项目试图了解听众是如何 将口语单词的语音变体识别为 说话者。作为实现这一目标的第一步，研究将集中在 通过以下方式对语音变异进行清晰而准确的描述 收集、转录和分析一个10万字的语料库 对话演讲。将进行两种类型的分析。音系学 分析将集中在开发一张语音变异图，该图 识别系统定期相遇，计算表格 变异，它们的频率，以及它们发生的背景。声学 将对变体进行分析，以制定详细的描述 与语音信号本身紧密相关的变化。结果来自于 这两项工作都应提供坚实的基础，在此基础上 可以在今后的工作中对音系变异进行有益的研究。

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.
