Correcting pronunciation in a foreign language, using ultrasound sonography.

本研究旨在探索在外语教学中运用超声技术进行语音教学的有效途径。目前研究的主要目标之一是，舌动图像的这种视觉信息将导致正确的发音正确的纠正。进行了以下六个方面的大量实验：[TYPE 1]假设日语学习者(大学生)以音素[ae]、[r]、[L]、[t]开头的英语单词发音正确，超声成像训练有效。结果：(1)前测：日语学习者发现目标单词发音困难。(2)使用B超和两台摄像机，被试能够通过观察超声图像并确认舌头位置和运动来修复他们的表现。[TYPE 2]假设以清辅音和清辅音为靶标，结果：在教学干预下，日语学习者的发音改正成功。数据显示，坚持超声波检查和两个张嘴/闭嘴摄像头将导致正确的发音方式是合理的。未来方向：可能建议在外语课堂上，学习者应该使用超声波检查来提高他们的发音。此外，将在不久的将来进行校正由每个被摄体的头部运动引起的每个画面的移动的编程。

This research aims to investigate the effective instructional approach to the pronunciation in foreign language teaching, using ultrasound sonography. One of the main objectives in the current investigation is that such visual information of tongue movement images will lead to the proper correction of correct pronunciation. A lot of six experiments have been conducted as follows;[type 1] It is assumed that such English words starting the phonemes[ae], [r], [l], [t], which Japanese learners of English(university students) will be pronounced correctly, and the training using ultrasound imaging will be effective.Results :(1) pre-test : Japanese leaners found it difficult to pronounce the target words.(2) Using ultrasound sonography and two video cameras, the subjects were able to repair their performance, by looking at ultrasound images and confirming the tongue position and movements.[type 2] It is assumed that with voiced and voiceless consonants targeted, audio training will be effective using ultrasound sonography.Stimuli : coat-goat, curl-girl, etc.Results : Japanese learners were successful in modifying their pronunciation, owing to the instructional intervention. The data showed that it may be plausible to insist that ultrasound sonography and two video cameras of mouth opening/closing will lead to correct ways of pronunciation.Future directions : It may be suggested that in foreign language classrooms, learners should use ultrasound sonography in order to improve their pronunciation. Further, the programming of correcting the movement of each picture caused by head movements of each subject will be made in the near future.
