“Residual” Voices from a Perspective of Articulatory Dynamics: A Case Study in Japanese Idioms Kuchi-o Togaraseru (Purse One's Lips) and Kuchi-o Yugameru (Curl One's Lips), and their Surroundings

Abstract

This article qualitatively and quantitatively examines the pronunciation methods for each of the following four types of speech in Japanese: (a) objecting using childlike speech, (b) adult expressions of indebtedness, (c) directly quoting the speech of an object of disdain, and (d) “unmarked” utterance. By using video imaging and MRI movie data, we clarify the connection between these speech types and their articulatory dynamics which the idiomatic expressions kuchi-o togaraseru (purse one's lips) and kuchi-o yugameru (curl one's lips) do not cover fully.
