영어 비모국어 화자의 외국인 액센트 지각에 미치는 어휘 효과: 언어 숙달도와의 상호작용을 중심으로 = The Effect of Lexical Frequency on Perception of Foreign Accent in Non-native English Speech and Its Interaction with Language Proficiency

다국어 초록 (Multilingual Abstract)

Among the many factors that affect the seech perception, the present study aims to examine lexical effect on non-native perception of foreign accented speech and its interaction with language proficiency. A majority of previous studies on foreign accent have largely put an focus on speech production factors such as the first language, age of learning and length of residence. Relatively small amount of work has been accumulated in the field of foreign accent perception. In the present study, English native listeners and advanced and intermediate learners of English participated in an auditory foreign accent rating experiment. They listened to the target stimuli and rated the foreign accent by clicking an appropriate button in a seven-point scale presented on the screen. The lexical information such as token frequency turned out to be an factor affects the foreign accent perception. Also, results revealed the significant effect of lexical frequency and language proficiency and their interaction: high frequency words were consistency rated as less accented than lower frequency ones in English native and advanced learners of English, but not in intermediate learners of English.
