Abstract
With regard to the accentuation of alphabetic acronyms in the Chuuooshiki (Central-type) Accent which distributes in the Kinki and Shikoku district, this paper clarifies the following points. (1)Unaccented patterns are used mainly by young people, and the use of these patterns is partly due to the influence of standard Japanese. (2)Patterns which belong to Teikishiki(low-beginning register) are used both by young and old people in the central part of the Kinki district. In the peripheral area Teikishiki patterns are rarely used. (3)The correlation between the speaker's familiarity with a word and the rate of use of Teikishiki patterns is not very obvious.
