A Perceptual Study of Stops by Korean learners of Thailand and Cambodia
The purpose of this study is to examine how it influences on the perception of the stops in Korean whether a mother language of a learner has tonal system or not.
The Korean stop series are very peculiar, being compared with the typological tendency presented in Meddieson(1984). Therefore, there have been the studies on the stops of Korean and the studies for teaching it. However, the studies has been not enough about what aspects the korean stops are acquired through by korean language learners.
When Korean native speakers identify a category of a stop, the weighed perceptual cues are VOT and the pitch of the following vowel. According to Jang(2012), there appear the differences between the speakers of Seoul dialect (non-tonal dialect) and of Dae-gu dialect (tonal dialect) when using these cues. Meanwhile, according to Lardiere(2013), L2 language knowledge of a learner who can speak exactly like, or on a comparable level with a native speaker might not be the same with a native speaker’s knowledge. Then, when hearing the stops in Korean in which even native speakers show different aspects of using perceptual cues depending on the dialectic areas, how would appear the using aspects of perceptual cues by the learners possessing his/her mother tongues with or without tonal system? If any, what differences would be?
With this theme of the study, perception experiments of the stops in Korean have been carried out. The experiments consist of as follow:
First, the experiment to assess the sensitivity of the learners on the stops in Korean. Second, the experiment to listen the contrary cues simultaneously and identify the voicing types. Third, the experiment to identify the voicing types after listening the variants of manipulated labial and alveolar stops followed by a vowel /a/.
The participants of the experiments were selected from Thai and Cambodian. It is for identifying the influences on perception of the stops, with or without tonal system in a mother tongue of a learner, by comparing Thai which is a tonal language and has stops with the voiced, unaspirated voiceless, and aspirated voiceless and Khmer language, a non-tonal, with the stops of unaspirated voiceless, aspirated voiceless, and the implosive. Also, because it was difficult to figure out if their categorization came from errors or mistakes, because of the limited time of experiment, the subjects were limited to the high level learners who have reached almost the ultimate attainment of Korean language.
As the results of the experiment, the Thai learners were using the pitch of the following vowels as the almost single cue of perception in differentiating lenis from aspirates. The rate of fortis response was very low, which seems because of using another acoustic feature as a perceptual cue other than pitch of the following vowel or VOT.
The Cambodian learners were also using pitch of the following vowel as a major perceptual cue in differentiating lenis from aspirates, though influenced more or less by VOT. Also, in short sections of VOT, fortis responses were prevail regardless pitch.
Therefore, it was found out that with or without tonal system in their mother languages of the learners have influences on using of perception cues for identifying stop categories in Korean. However, as the aspects of the influences seem like contrary to the dialectic aspects of korean native speakers, further discussions about it are necessary.
