FRENCH /y/-/u/ CONTRAST IN JAPANESE LEARNERS WITH / WITHOUT ULTRASOUND FEEDBACK: VOWELS, NON-WORDS AND WORDS

Abstract : This study investigated French /y/ and /u/ produced by one native speaker (NS) and seven Japanese-speaking learners; four of them received lessons on /u/ with ultrasound visual feedback of the tongue shape and position. Acoustic measurements of 10 repetitions of six words (coronal context) are compared to those of isolated /y/ and /u/, and of the non-words /tyty/ and /tutu/, both before and after the ultrasound lessons, in terms of i) Euclidean distance (ED) between /y/-/u/; ii) the distance F2-F3 of /y/; and iii) the distance F1-F2 of /u/. The isolated vowels were closest to NS's, followed by monosyllabic words, disyllabic ones, and then non-words. The values of all learners are significantly different from NS's at the first recording, but those of the learners having received ultrasound lessons approached NS's after the lessons.
