Enhancing Perception Recognition Spoken Words

项目摘要

This project examines the perception of English lexical stress (e.g., “desert” vs. “dessert”) by listeners from various language backgrounds in order to advance several important questions about the nature of speech perception and learning. The sound system of a person's native language influences not only how second-language learners produce words but also how they recognize words, making it difficult for second-language learners to hear sound contrasts that do not distinguish words in the native language or that differ in how they distinguish words in the native and second languages. These difficulties can in turn impact second-language learners’ ability to understand speech in their second language, thus causing important communication breakdowns, and they can exacerbate the degree of foreign accent that second-language learners typically evidence in speech production. This project seeks to clarify and explain the nature of this native-language influence by investigating a linguistic phenomenon that plays a critical role in spoken-word recognition across languages but has been under-investigated: lexical stress. The project’s specific goals are threefold. First, the project will elucidate whether the cue-weighting theory of speech perception can provide a strong theoretical framework for understanding the listening difficulties that second-language learners encounter with lexical stress, and for developing training stimuli and methods to enhance the perceptual learning of lexical stress. Second, it will help resolve theoretical debates about the mechanisms underlying second-language perceptual learning, the nature and robustness of second-language perceptual representations, and the degree to which adult second-language perceptual learning remains malleable. Third, it will provide a theoretical foundation for the teaching of second-language speech perception, enabling instructors to tailor teaching practices according to students’ native language and individual abilities, and the effectiveness of training stimuli and methods. Participants will complete cue-weighting perception experiments, sequence-recall experiments, visual-world eye-tracking experiments, and perceptual training experiments, as well as proficiency and perceptual aptitude tests.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目研究了来自各种语言背景的听众对英语词汇压力的感知（例如，“甜点”与“甜点”），以促进有关语音感知和学习的本质的几个重要问题。一个人的母语的声音系统不仅会影响第二语言学习者如何产生单词，而且会影响他们如何识别单词，这使得第二语言学习者很难听到声音对比，这些声音对不区分母语，或者在本地语言和第二语言中区分单词的方式很难。这些困难反过来可能会影响第二语言学习者以第二语言理解语音的能力，从而导致重要的沟通崩溃，并且可以加剧第二语言学习者通常在语音生产中证明的外国口音程度。该项目旨在通过调查一种语言现象来澄清和解释这种本地语言影响的性质，该语言现象在跨语言的口语识别中起着至关重要的作用，但受到影响不足：词汇压力。该项目的具体目标是三倍。首先，该项目将阐明语音感知的提示加权理论是否可以提供一个强大的理论框架，以理解第二语言学习者遇到词汇压力的聆听难度，以及开发训练刺激和方法以增强对词汇压力的知觉学习。其次，它将有助于解决有关第二语言知觉学习的机制，第二语言感知表征的性质和鲁棒性以及成人第二语言知觉学习的程度。第三，它将为第二语言语音感知的教学提供理论基础，从而使讲师能够相应地量身定制教学实践。给学生的母语和个人能力，以及训练刺激和方法的有效性。参与者将完成提示感知实验，序列回顾实验，视觉世界的眼神传播实验以及知觉培训实验，以及熟练程度和知觉能力测试。这奖反映了NSF的立法任务，并通过对基金会的知识优点进行评估，并以评估为基础，并将其视为PRICENTIAL。
