Does the dialect you speak determine how you hear the speech around you? With National Science Foundation support, Dr. Tyler Kendall and Dr. Valerie Fridland will conduct twenty-four months of linguistic research investigating how vowel perception is affected by dialect experience. Utilizing web-based perception experiments to gain participation from across the U.S., and recording speech from a subset of these participating subjects, the project will investigate what links exist between the perception and production of vowel categories (e.g., "ee" and "ih") and how these categories are mediated by variation at the level of the community and the individual. In particular, the research will examine whether distinctive regional vowel changes that affect three main dialects of American English (Northern, Southern and Western) are contributing to greater diversity in speech processing, in addition to speech production, and whether the degree to which individuals show such vowel changes themselves affects their speech processing in relation to their community norms. To gain a better understanding of the impact of social influences on speech perception, this research will investigate whether listeners' categorization of vowels is also affected by their expectations regarding learned social distinctions among speakers, such as regional affiliation or gender.Increasing evidence suggests that socially derived linguistic variation provides more than simply clues to social identity, and, in fact, plays a pivotal role in the actual processing and decoding of the speech signal itself. Research in this area should prove to have applied benefits such as informing educational approaches to non-native language/dialect populations and also to the development of voice recognition technologies. Further, comparative examination of the productive and perceptual range of speakers affected by different dialect experiences will inform both speech and hearing science and sociolinguistic research, contributing to basic theories about the nature of speech processing and of sound change.

你说的方言是否决定了你如何听到周围的讲话？在国家科学基金会的支持下，泰勒肯德尔博士和瓦莱丽弗里德兰博士将进行为期24个月的语言学研究，调查方言经验如何影响元音感知。利用基于网络的感知实验来获得来自美国各地的参与，并记录来自这些参与主体的子集的语音，该项目将调查元音类别的感知和产生之间存在什么联系（例如，“ee”和“ih”）以及这些类别如何通过社区和个人层面的差异来介导。特别是，该研究将探讨是否独特的区域元音变化，影响美国英语的三个主要方言（北方，南方和西部）的语音处理更大的多样性，除了语音生产，以及是否在何种程度上个人表现出这种元音变化影响他们的语音处理与他们的社区规范。为了更好地理解社会影响对言语感知的影响，本研究将调查听者对元音的分类是否也受到他们对说话者之间习得的社会差异的期望的影响，例如区域归属或性别。越来越多的证据表明，社会衍生的语言变异不仅仅提供了社会身份的线索，事实上，在语音信号本身的实际处理和解码中起关键作用。这一领域的研究应证明具有应用效益，例如为非母语/方言人口提供教育方法，以及开发语音识别技术。此外，对受不同方言经验影响的说话者的生产和感知范围的比较研究将为言语和听力科学以及社会语言学研究提供信息，有助于有关言语处理和声音变化本质的基本理论。
