This study investigates the role of phonology in spontaneous imitation in Seoul Korean speakers’ imitation of aspirated stops by comparing the primary and non-primary cues. Seoul Korean aspirated stops are differentiated from stops of other phonation types by at least two distinct acoustic properties, stop VOT and f0 of the post-stop vowel, with the latter being the primary cue. In the imitation experiment, Seoul Korean speakers heard and shadowed model speech that contained aspirated stops mani

Kwon, Harim. 2007. A Phonetic Analysis of Advanced Korean EFL Learners' English Reduced Vowels. Korean Journal of English Language and Linguistics 7-4, 547-564. This study investigates the phonetic properties of English reduced vowels produced by advanced Korean EFL learners. Five native speakers of Korean (experimental group) and two native speakers of English (control group) participated in the experiment. While pronouncing English reduced vowels, Korean EFL learners were different from Englis

This study examines the relation between plosive aspiration and post-plosive f0 (fundamental frequency) in the production and perception of the laryngeal contrast in Mandarin. Production data from 25 Mandarin speakers showed that, in word onsets, VOTs (voice onset time) of aspirated and unaspirated plosives were different, as expected. At the same time, the speakers produced different post-plosive f0 between aspirated and unaspirated plosives, but the difference varied according to the lexical t

Cross-language research on consonant cluster production has shown that consonant clusters in different languages are produced with different degrees of articulatory timing lags. The present study examines perceptual sensitivity to these cross-linguistic timing differences in consonant clusters. Native German listeners were tested on an AXB similarity judgment test using stimuli including consonant clusters produced by German and Georgian speakers. (German consonant clusters are produced with rel

Previous research on spontaneous imitation examines how speaker-listeners’ own production changes after hearing a few minutes of model speech, and suggests that speech perception and production are closely related. This dissertation investigates how cue primacy influences imitation by separately manipulating two co-varying cues differing in their primacy for one phonological category. By examining how similarly or differently primary and non- primary cues operate in spontaneous imitation, this d

We explore the influence of native timing patterns on nonnative speech perception, by asking whether a nonnative CVCV sequence can be perceived as CCV when the temporal organization of nonnative CVCV is similar to native CCV. To explore this question, Georgian listeners are tested on a CCa-CVCá discrimination in French. Georgian has a rich word-onset cluster inventory, with component consonants loosely timed. The loose timing often, though not always, results in a schwa-like CC transition. Frenc

This study investigates the phonetic properties of English reduced vowel of Korean EFL learners. Five native speakers of Korean (experimental group) and two native speakers of English (control group) participated in the study. While pronouncing English reduced vowels, Korean EFL learners were different from English native speakers in two acoustic features. Firstly, the learners' duration of the reduced vowels was significantly longer than that of the native speakers. Secondly, the vowel quality

The current study explores whether Mandarin initial and medial voiceless unaspirated and voiceless aspirated stops differ in their tongue positions and post-vocalic voicing during closure. Ultrasound tongue imaging and acoustic data from five Mandarin speakers revealed (1) no consistent pattern for tongue positions among speakers, and (2) no difference in degree of voicing during closure between the two stop series. These findings suggest that tongue position is not a reliable articulatory corre
