The Consonantal and vocalic information to the Perception of Japanese initial stops by Osaka speaker and Tokyo speaker This study noted the difference between the Osaka dialect and the Tokyo dialect in the balance of the politeness degree of the pronunciation of the consonant and the vowel, and aimed that the difference of perception was observed between the Osaka dialect speaker and the Tokyo dialect speaker. It experimented that identified the voicing contrast and the articulatory port by both speaker group in word initial stops. For experiment, the source sounds were divided to "Consonant part" and "Vowel part", and were connected "Consonant part" and "Vowel part" of another sounds. The degree of the affection of Vocalic information or Consonantal information used in identifying both the voicing contrast and the articulatory port as perceptional clue was examined. As a result, the following findings were obtained. First, the difference of the perceptual distinction was both observed between the two groups at a part of combination. Second, the Tokyo speaker used Consonantal information for identification as a perception clue whereas the Osaka speaker used Vocalic information in listening the sounds that connected the voiced "Vowel part" with the voiced "Consonant part". In conclusion, it has been understood that the Tokyo speaker uses Consonantal information to the identification of the voicing contrast, whereas Osaka speaker uses vocalic information in the the sounds that join voiced "Consonant part" and voiceless "Vowel part" together. In word initial stops, it can be said that there is a difference in the balance of the politeness degree of the consonant and the vowel between the Osaka dialect and the Tokyo dialect in perception because Osaka speaker and Tokyo speaker's perceptional distinction are different.

本稿は子音と母音の発音の丁寧度のバランスにおいて大阪方言と東京方言間で差異が見られることに着目して、知覚においても大阪方言話者と東京方言話者の間に差異が観察されることを予測し、両話者群による語頭破裂音の有声性と調音位置を同定する実験を行った。実験においては、原音声を｢子音部｣と｢母音部｣に分節し、別の音声の｢子音部｣と｢母音部｣と継ぎ合わせた加工音声を作り両方言話者に聞かせた。それを聞いて両方言話者が有声性と調音位置を同定する祭、優先的な手がかりとして用いる｢母音部｣情報や｢子音部｣情報の関与の度合いを調べ、両方言話者間に差異がみられるかを考察した。その結果、以下のような知見が得られた。一部の組み合わせにおいて両方言話者の間に知覚判断の違いが観察された。有声の｢子音部｣と有声の｢母音部｣を継ぎ合わせた音声に対し、大阪方言話者は｢母音部｣情報を、東京方言話者は｢子音部｣情報を優先的な手がかりとして同定に用いた。また有声の｢子音部｣と無声の｢母音部｣を継ぎ合わせた音声に対し、有声性の同定に大阪方言話者は｢母音部｣情報を、東京方言話者は｢子音部｣情報を用いることが分かった。語頭破裂音の知覚において、大阪方言話者と東京方言話者の知覚傾向が異なることから、知覚においても大阪方言と東京方言の間には子音と母音の丁寧度のバランスに差異があると言えよう。
