Airflow patterns of voiced geminate stops in Japanese

Perceptual training of singleton and geminate stops in Japanese language by Korean learners

We aim to build up an effective perceptual training paradigm toward a computer-assisted language learning (CALL) system for second language. This study investigated the effectiveness of the perceptual training on Korean-speaking learners of Japanese in the distinction between geminate and singleton stops of Japanese. The training consisted of identification of geminate and singleton stops with ...

Relational Timing or Absolute Duration? Cue Weighting in the Perception of Japanese Singleton-Geminate Stops

Relational timing has been proposed as a solution to the problem of variability across durational properties of speech arising with changes in speaking rate. The current study investigates the role of absolute and relational timing cues in perception of Japanese stop length (singleton/ geminate) categorization. Absolute (stop duration) and relational (ratio of stop duration to preceding mora du...

Correspondence of perception and production boundaries between single and geminate stops in Japanese

The theory of relational acoustic invariance [Pickett, E. R., et al. (1999). Phonetica 56, 135-157] was tested with the Japanese stop quantity distinction in disyllables spoken at various rates. The questions were whether the perceptual boundary between the two phonemic categories of single and geminate stops is invariant across rates, and whether there is a close correspondence between the per...

Production of single and geminate stops in Japanese three- and four-mora words.

This study examined the durational structure of single and geminate stop distinction produced in three- and four-mora words of Japanese, (C(1))V(1)(C(2))C(2)V(2)X [(C(2))C(2) = the contrasting consonants; X = a CV mora, the moraic nasal, or a long vowel as part of V(2)]. The questions addressed were how factors such as speaking rate, segmental variability, and moraic composition of words affect...
