    The purpose of this paper is to examine the ability of Japanese native speakers to identify the Tokyo accent, which is standard Japanese. A total of 126 university students from four areas, where their accents have different systems, participated in a perception test eight times over the course of one month. The data collected were analyzed in terms of the number of tests, intonation types, accent patterns, number of morae, type of morae, and type of special morae. Error analysis was also conducted. The rate of correct answers got better with each test regardless of accent system and reached 87% in the last test for listeners of Tokyo-shiki (Tokyo type) accent, 83% for listeners of no accent, 80% for listeners of Keihan-shiki (Kyoto-Osaka type) accent, and 69% for listeners of Nikei-shiki (two patterns) accent. The findings will help develop tools to improve listening skills for the Tokyo accent.

    This study examined the effects of phonological factors on the perception of English syllables and lexical stress by native Japanese speakers. Factors investigated were syllable complexity, position of the consonant cluster, number of syllables, stress position, vowel structure, silent words, and syllabic consonants. The Syllable Count Task (SCT) and the Stress Identification Task (SIT) were conducted. In both tasks, performance declined as the number of syllables increased. In addition, for one-syllable words, as the complexity of the syllable structure increased, SCT performance decreased. Furthermore, as the stress position came closer to the coda position of the word, SIT performance declined.

    A perception experiment was conducted to determine how accurately Chinese learners of Japanese can identify four emotions (Happy, Angry, Sad and Neutral) in Japanese emotional speech. The result showed that the accuracy of recognition was worst in “Happy”, followed by “Anger”, “Sad”, and “Neutral”, and was influenced by their learning experience. Acoustic analysis revealed that there were no significant differences between (1) “Happy” and “Angry” in F0mean, F0level, F0max, F0span, Duration and IntensityMean, and (2) “Neutral” and “Sad” in F0level, F0max, F0span, Duration and IntensityMean, thus potentially explaining why these two emotions were especially confused.

    This is a report on an examination and evaluation of Japanese learners’ English using multiple metrics: phoneme substitution, epenthesis, elision, primary stress, rhythm and overall goodness. In the examination, the difficulty in producing weak/lax vowels was highlighted. The correlation analysis between overall goodness and each of the other metrics indicated that improving both segmental and prosodic features is essential for Japanese learners to achieve good pronunciation. A systematic pronunciation evaluation using multiple metrics is beneficial not only for a deeper and broader understanding of Japanese English but also to the development of pronunciation teaching and learning.

    The objective of this study was to examine whether vowel duration and lexical decision time differ between CnV, CnVC (voiced), and CnVC (voiceless) words. After presenting monosyllabic English and nonsense words with onset consonant clusters to Japanese learners of English and native English speakers, participants were asked to judge whether the test words were English words or nonsense words and pronounced the words. Their response time was measured, and their pronunciation was recorded to compare vowel durations. Their CVC test words had shorter vowels than CV words, and vowels preceding unvoiced consonants were shorter than vowels preceding voiced consonants. These effects were more conspicuous for native English speakers, though the same effects were detected for the Japanese speakers. Comparison of lexical decision time showed native English speakers responded quicker than Japanese speakers, and that nonsense words were more difficult to judge than English words for both English and Japanese speakers. No significantly high correlations were detected between learners’ English proficiency levels and their vowel durations or lexical decision time.
