项目摘要

In order for speech communication to be successful speakers must be able to deliver their messages clearly to their listeners. For example, when a listener does not understand what was said by a speaker the first time, the speaker may repeat what they said in a clearer manner so that the listener can understand it. This seemingly simple act of enhancing intelligibility of speech for a listener is often carried out naturally by fluent speakers of the language, yet it can be difficult for people who produce less fluent and less intelligible speech, such as non-native speakers of the language. Not being understood by listeners has very real consequences for non-native speakers as it can significantly decrease their opportunities to obtain jobs and education, and more broadly, to participate in society as an equal member. The significance of this issue is highlighted by the growing population of non-native English speakers in the U.S. This project seeks to better understand why it can be difficult to enhance speech intelligibility in a non-native language by examining how speakers of different linguistic backgrounds use speech enhancement strategies in different communication contexts. The results of this project could inform the development of methodologies for second language learning as well as interventions for clinical populations who may experience difficulty enhancing their speech intelligibility. The goal of this project is to understand two aspects of what contributes to enhancing speech intelligibility: what kinds of strategies speakers use to enhance their speech and how these strategies are perceived by listeners. Specifically, the proposed experiments examine how a speaker’s ability to speak clearly is affected by different sources, such as the speaker's language background, characteristics of the speech materials (e.g., familiarity of the words or phrases), and characteristics of the communication context. Further, the project examines how speakers' attempts to enhance speech intelligibility translate to listeners' perception of this speech, including perceived degree of comprehensibility (how easy it is to understand the speech) and perceived degree of speaker effort (how hard the speaker is trying to speak clearly). This project will help us better understand the contributions from both speakers and listeners to enhancing speech intelligibility for a variety of native and non-native speaking populations.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.

为了成功地进行言语交际，说话者必须能够把他们的信息清楚地传达给听众。例如，当一个听众不理解说话者第一次说的话时，说话者可能会以更清晰的方式重复他们所说的话，以便听众能够理解。这种看似简单的增强听众语言可理解性的行为通常由流利的语言使用者自然完成，但对于那些不流利和不太容易理解的人来说，例如非母语的人。不被听众理解对非母语者有着非常真实的后果，因为这会大大减少他们获得工作和教育的机会，更广泛地说，会减少他们作为平等成员参与社会的机会。这个问题的重要性是突出的非英语母语的人口在美国这个项目旨在更好地理解为什么它可以很难提高语音清晰度在非母语通过研究如何不同的语言背景的扬声器使用语音增强策略在不同的通信环境。该项目的结果可以为第二语言学习方法的发展以及可能难以提高语音清晰度的临床人群的干预提供信息。这个项目的目标是了解什么有助于提高语音可懂度的两个方面：说话人使用什么样的策略来增强他们的语音，以及这些策略是如何被听众感知的。具体来说，所提出的实验研究说话者清晰说话的能力如何受到不同来源的影响，例如说话者的语言背景，语音材料的特征（例如，单词或短语的熟悉度）以及通信上下文的特征。此外，该项目还研究了说话者试图提高语音清晰度的努力如何转化为听众对该语音的感知，包括感知的可理解程度（理解语音的容易程度）和感知的说话者努力程度（说话者试图清楚地说话的努力程度）。该项目将帮助我们更好地了解演讲者和听众对提高各种母语和非母语人群的语音清晰度所做的贡献。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
