5th International Conference on Spoken Language Processing
Usually the first vowel of the Japanese word 'susugi' (rinse) disappears, and so the pronunciation of 'susugi' is not [susugi] but [ssugi]. We made two psychophysical experiments. In the first one we shortened the part of [ss] of [ssugides] and [korewassugides] (This is rinse.) in 6 stages. [korewassugides] with shortened [ss] is easy to perceive as [korewasugides] (This is cedar) , but [ssugides] with shortened [ss] is not easy to perceive of [sugides] (Japanese cedar). In the second experiment we changed the pitches of [sugides] and researched how Japanese perceive these sounds.
