Japanese consonants compared with English with regard to prosthodontic dentistry

This is the introductory paper of the forthcoming series of papers on Japanese consonants compared with English, presented as a basic study for prosthodontic dentistry. Materials for our experiment are fifteen groups of Japanese and English words and phrases to be uttered by normal native speakers of Japanese and English respectively. They are speakers of a modified standard Japanese and the Hichiku (: part of northern Kyushu) accent of Japanese and those of standard British English, General American English and Eastern American English. Each of the fifteen groups of words and phrases contains a set of Japanese and English consonants to be examined and compared with each other. The phonetic apparatus to be used are the sound spectrograph, oscillograph, phono-laryngograph, flow-nasalitygraph, electro-palatograph, etc.
