몽골어 파열음의 음향적 특성이 몽골인 한국어 수준별 학습자의 한국어 파열음에 대한 음성인식에 미치는 영향 = The influence of the acoustic properties of Mongolian plosives on the speech perception of Korean plosives by Mongolian learners of Korean in different proficiency levels
The main purpose of this study is to investigate how Mongolian learners of Korean perceive Korean plosives which has a three-way contrast in terms of laryngeal features. 30 Mongolian learners participated in speech perception tasks, and they were divided into two groups based on their proficiency of Korean: 15 participants for a low level and 15 for a high level. In the tasks, the Mongolian participants showed a poor performance in discriminating plain stops from aspirated ones, regardless of their Korean proficiency level. This implies that Mongolian learners of Korean are not able to utilize the differences in VOT and F0 values as acoustic cues to correctly distinguish the Korean plosive series. Given that Mongolian learners can successfully discriminate Mongolian plosives only with the VOT cue, their sensitivity to F0 has been diminished. Thus, this can have a negative effect on their perception of Korean plosives, which leads us to conclude that sources of Mongolian learners’ errors in discriminating Korean plosives involve failure to employ F0 as a perceptual cue to their perception of non-native sound contrast.
