| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Kato et al. showed that given streams of sounds, listeners use amplitude changes to demarcate segmental boundaries. This study builds on this result and argues that amplitude changes facilitate categorization and discrimination of consonantal short/long contrasts in intervocalic position. Given non-speech stimuli mimicking VCV-sequences, larger amplitude changes in VC- and CV-transitions improved the perceptibility of the length of C. The result implies that in real speech, short/long contrasts are harder to perceive for more sonorous consonants. This conclusion in turn accords well with the phonological, cross-linguistic observation that geminates of more sonorous consonants are disprefered more strongly in natural languages, instantiating a case of contrast dispersion. | |
