X線マイクロビームによる調音運動研究の動向(<特集>音声研究の新しい手法)

抄録

The x-ray microbeam system is a unique instrument to measure the movements of multiple flesh-points of speech articulators, and the recently updated system at the University of Wisconsin provides the most reliable means among available all methods. This review describes the summary of the system, the author's experience and recent studies by several researchers. Recent progress in particular is the development of the speech production database of English and Japanese speakers, which elucidates articulatory variability, speaker characteristics, and dynamic behavior of soft-tissue speech organs based on the comparison of a large number of subjects.
