| Abstract(in English) | Segment length is distinctive in Japanese, e. g., /kaze/ ("wind") vs. /kaze :/ ("taxation"). Such length contrasts are known to be difficult to perceive for native speakers of a language, e. g., English, in which lexical contrasts are not signaled by duration alone. Past studies, however, have not thoroughly examined how learners' ability to categorize length contrasts is affected by stimulus variations such as stimulus length (word vs. sentence) and by identification training. To carefully investigate these effects, a series of perception experiments were conducted. Native English and native Japanese listeners participated in a single-stimulus two-alternative forced-choice identification task using a synthesized stimulus continuum between a pair of Japanese words that minimally differed in the length of a vowel as well as a continuum between a pair of sentences that included these words at a fixed position. The English listeners were tested for a second time after five days of identification training. Overall results show that English listeners' identification boundaries were sharpened by the identification training, although they did not reach the level of native listeners. Furthermore, English listeners' identification boundaries in the sentence condition shifted downward (toward the shorter end) after perceptual training. This result suggests that even non-native listeners can adjust their identification boundaries according to the difference in speaking rate between word and sentence conditions. |
