The Mutual Intelligibility of Different World English Varieties : The Correlation between Production and Perception and the Measurable Effects of Prosodic Parameters on Intelligibility

本研究旨在探讨不同世界英语变体的相互可理解性，将重点放在产生和感知之间的相关性以及韵律参数对可理解性的可测量影响上。在本研究中，我们进行了一些实验，包括生产、识别和感知测试，以检验为实现研究目的而提出的主要假设。大量非英语为母语的人作为测试对象参与了实验。然后，对所有数据进行分析和仔细审查。因此，有大量的研究结果与以日本为母语的人所说的英语的相互可理解性有关。

This research sets out to investigate the mutual intelligibility of different World English varieties, placing the major focus on the correlation between production and perception and the measurable effects of prosodic parameters on intelligibility. For this study, some experiments including production, recognition, and perception tests were conducted to examine the main hypotheses which were posited to achieve the purpose of the study. A large number of non-native speakers of English participated in the experiments as a test subject. Then, all data were analyzed and scrutinized. As a result, there was a substantial number of findings related to the mutual intelligibility of English spoken by native speakers of Japanese.
