Typological Studies of Tonal Changes Based on Acoustic Analyses of the Sanuki-type Accent Systems on Ibuki-jima and Surrounding Areas

本研究利用该资助金进行了以下领域的口音实地研究，从而能够使用个人电脑和数字硬盘录音机收集数字化声音数据（罗兰R-4）：（1）观音寺（香川县），阿波池田（德岛县）和其他地区（2）多度津町，和米托约，和淡马岛，志岛群岛（香川县）（3）京都（亚瓦塔市）和大坂（岸和田、丰中市）（4）吉川市（德岛县）、阿基和高知（高知县）和其他地区（5）伊吹岛和观音寺（香川县）、川江（爱媛县）典型的京坂式口音系统的声音数据（大坂和京都），和其他非赞岐系统在同一四国地区，如阿基和高知市，也收集了。这些系统与萨努基系统的对比研究表明：（a）非重音H调在伊吹岛的（高音）音高模式明显不同于其他具有相同H-音调模式的系统，如德岛、大坂、京都、阿基和高知;（B）在大部分萨努基地区，非重音H-音调模式显示出音高逐渐下降的音高模式，这与所谓的“加口式”不同（略下降）'口音模式观察伊吹岛;（c）在Sanuki型系统中，无重音L音（低音）模式还表现出一些独特的语音特征，与京坂的语音特征有明显不同（Kyoto-Osaka）型系统，因为（1）它们不以比其他模式相对较低的音高开始，（2）一般音高范围相对较高而不是较低，和（3）他们不像京都和大坂的相应模式那样在每个乐句的结尾处显示出上升的音高模式。

The fieldwork on accents in the following areas was conducted by this grant, which enabled the digitalized sound data to be collected by using a PC and a digital hard-disc recorder (Roland R-4):(1) Kan'onji (Kagawa Prefecture), Awa-ikeda (Tokushima Prefecture) and other areas(2) Tadotsu, and Mitoyo, and Awa-shima, Shishi-jima islands (Kagawa Prefecture)(3) Kyoto (Yawata city) and Osaka (Kishiwada and Toyonaka city)(4) Yoshinogawa-shi (Tokushima Prefecture), Aki and Kochi (Kochi Prefecture) and other areas(5) Ibuki-jima, and Kan'onji (Kagawa Prefecture), and Kawanoe (Ehime Prefecture)The sound data of the typical Keihan-type accent systems (Osaka and Kyoto), and other non-Sanuki systems in the same Shikoku area, such as Aki and Kochi city, were also collected. The comparative studies between these systems and the Sanuki system revealed the following results:(a) The unaccented H-tone (high-tone) pitch pattern in Ibukijima is clearly different from those of other systems with the same H-tone patterns, such as Tokushima, Osaka, Kyoto, Aki, and Kochi;(b) In most of the Sanuki areas, the unaccented H-tone patterns show a pitch pattern with gradual declining pitch, which are different from the so-called 'Kakou-shiki (slightly declining)' accent pattern observed in Ibuki-jima;(c) In the Sanuki-type systems, the unaccented L-tone (low-tone) patterns also show some peculiar phonetic features, which clearly differs from those in Keihan (Kyoto-Osaka) type systems, in that (1) they do not begin with relatively lower pitch than other patterns, (2) the general pitch range is relatively high rather than low, and (3) they do not show a rising pitch patterns toward the end of each phrase as do the corresponding patterns in Kyoto and Osaka.
