DESCRIPTION (provided by applicant): Finding an effective and efficient method for teaching speech sounds has been of the great interest in language related fields. There are many consonant training studies, but there is limited research on vowel training. Since vowels convey not only segmental but also suprasegmental information, it is necessary to improve both perception and production of vowels in order to increase one's communicative efficiency. The present research is on training methods for vowels acquired in a second language. Trainees will be learners of American English (AE) who have a common native language. The first purpose of the present research is to evaluate the impact that different ranges of stimulus sets used in a perceptual training have on the effectiveness of training. A pre test post test design will be employed to gauge change in trainees' performance resulting from training. The second purpose of this study is to assess the transfer of perceptual training to production. All trainees will record their speech before and after training. Recorded speech samples will be acoustically analyzed as well as evaluated by native speakers of AE for intelligibility and accentedness. The third purpose of this study is to assess the possibility of long-term retention of the training effects. These results will provide empirical support for a theoretical framework for the speech perception-production link. These results can also be used to extend the research to propose new vowel training methods.

描述（由申请人提供）：寻找一种有效而有效的教学语音语音方法对语言相关领域引起了极大的兴趣。有许多辅音培训研究，但是对元音培训的研究有限。由于元音不仅传达了节段，而且传达上段信息的信息，因此有必要提高元音的感知和产生，以提高人们的交流效率。目前的研究是关于以第二语言获取的元音的培训方法。学员将是具有通用母语的美国英语学习者（AE）。本研究的第一个目的是评估感知训练中使用的不同刺激集对训练有效性的影响。测试前的测试设计将用于衡量培训导致学员的表现的变化。这项研究的第二个目的是评估感知培训向生产的转移。所有学员将在培训前后记录他们的演讲。记录的语音样本将进行声学分析，并由AE的母语人士评估，以了解清晰度和重音。这项研究的第三个目的是评估长期保留培训效应的可能性。这些结果将为语音感知链接的理论框架提供经验支持。这些结果也可以用于扩展研究以提出新的元音训练方法。
