| Research Abstract |
Acoustic features of affricates [ts] and [t〓], and a fricative [s] in Japanese were investigated to clarify good variables for consonant discrimination. It was revealed that acoustic features in the time domain areefficient to discriminate consonants with a different manner of articulation such as [t〓]-[s] and [t〓]-[s]. By contrast, acoustic features in the frequency domain are efficient to discriminate consonants with a different place of articulation such as[ts]-[t〓] and [t〓]-[s].
