Abstract

<p>The study of foreign accent observed in the speech generated by learners of Japanese is one of the most important challenges in the phonetic study of the teaching of Japanese as a second language. The current author believes that a large-scale database of learners' speech is indispensable for the full-fledged scientific study of foreign accent phenomena. The main reason for this belief stems from the failure of past studies of contrastive phonology, which revealed the sterility of rule-based, top-down analysis in this field. In addition to this, recent progress in automatic speech recognition of mother-tongue speech convincingly demonstrates the effectiveness of a statistical, bottom-up approach as represented by the corpus-based construction of acoustic models. In the last half of the paper, issues regarding the corpus design, construction, and analysis are discussed based upon the author's personal experiences in corpus compilation. The paper ends with the clarification of the role that should be played by the Society for Teaching Japanese as a Foreign Language in the infrastructure development for the corpus-based analysis of the teaching of Japanese as a foreign language.</p>
