This study examines cross-linguistic variation in the location of shared vowels in the vowel space across five languages (Cantonese, American English, Greek, Japanese, and Korean) and three age groups (2-year-olds, 5-year-olds, and adults). The vowels /a/, /i/, and /u/ were elicited in familiar words using a word repetition task. The productions of target words were recorded and transcribed by ...

This study examines the acoustic characteristics of English high tense and lax vowels (/i, I, u, ʊ/) and the perceptual difference of those vowels between English speakers and Korean speakers of English. In Experiment I, the first three formant values and duration of the four vowels in /hVd/ carrier were measured. The result shows that the high tense vowels have larger F2–F1 values and longer d...

How Javanese (L1) learners of English (L2) produce durational features of vowels has received increasing interest in the study of second language acquisition because the vowel systems are very disparate. The present production experiment attempts to shed light on the interference by Javanese (L1) on English vowel production (L2). The results are discussed with respect to differences in the vowe...

We have investigated whether variation in vowel insertion after word-final English and French postvocalic plosives in Korean adaptation has changed at a two-decade interval by collecting English and French loanword data in the early 1990s and the year 2011. The comparison of our 2011 data to the early 1990s data has revealed that the overall frequency of final vowel insertion and that of no vow...

The purpose of this study was to examine the effect of reduced vowel working space on dysarthric talkers' speech intelligibility using both acoustic and perceptual approaches. In experiment 1, the acoustic-perceptual relationship between vowel working space area and speech intelligibility was examined in Mandarin-speaking young adults with cerebral palsy. Subjects read aloud 18 bisyllabic words...
