This study is a follow-up study of Han and Kang (2013) and Kang and Han (2013) which examined cross-generational changes in the Korean vowels /o/ and /u/ using acoustic analyses of the vowel formants of these two vowels, their Euclidean distances and the overlap fraction values generated in SOAM 2D (Wassink, 2006). Their results showed an on-going approximation of /o/ and /u/, more evident in female speakers and non-initial vowels. However, these studies employed non-words in a frame sentence. To see the extent to which these two vowels are merged in real words in spontaneous speech, we conducted an acoustic analysis of the formants of /o/ and /u/ produced by two age groups of female speakers while reading a letter sample. The results demonstrate that 1) the younger speakers employed mostly F2 but not F1 differences in the production of /o/ and /u/; 2) the Euclidean distance of these two vowels was shorter in non-initial than initial position, but there was no difference in Euclidean distance between the two age groups (20’s vs. 40-50’s); 3) overall, /o/ and /u/ were more overlapped in non-initial than initial position, but in non-initial position, younger speakers showed more congested distribution of the vowels than in older speakers.

20세기 초 한국어 단모음의 음향음성학적 연구

한정임(Han, Jeong-Im),김주연(Kim, Joo-Yeon) 한국음성학회 2014 말소리와 음성과학 Vol.6 No.1

The current study presents an instrumental phonetic analysis of Korean monophthong vowels in the early twentieth century Seoul Korean, based on audio recordings of elementary school textbooks Botonghakgyo Joseoneodokbon (Korean Reading Textbook for Elementary School). The data examined in this study were a list of the Korean mono syllables (Banjeol), and a short passage, recorded by one 41-year-old male speaker in 1935, as well as a short passage recorded by one 11-year-old male speaker in 1935. The Korean monophthongs were examined in terms of acoustic analysis of the vowel formants (F1, F2) and compared to those recorded by 18 male speakers of Seoul Korean in 2013. The results show that in 1935, 1) /e/ and /?/ were clearly separated in the vowel space; 2) /o/ and /u/ were also clearly separated without any overlapping values; 3) some tokens of /y/ and /ø/ were produced as monophthongs, not as diphthongs. Based on the results, we can observe the historical change of the Korean vowels over 80-90 years such as 1) /e/ and /?/ have been merged; and 2) /o/ has been raised and overlapped with /u/.

On the development of anticipatory coarticulation in Korean/English interlanguage

Jeong-Im Han(한정임) 한국음운론학회 2006 음성·음운·형태론 연구 Vol.12 No.1

  The present study probes the question of various developmental patterns of anticipatory coarticulation, through CV vs. V-to-V coarticulations in L2 sound acquisition, based on the previous claims that these two types of coarticulations may follow different development patterns (Repp 1986), and that phonetic implementation becomes automatic through long period of learning (Kingston and Diehl 1994). Five repetitions of the CV in a carrier sentence ‘I like the ___,’ where C=/t/ or /s/, and V=/i, æ, u/ were recorded by three different groups such as native Korean speakers with a low level of English proficiency (NK), and native Korean speakers with a higher level of English proficiency (bilinguals) as well as native English speakers (NE), and the VOT values of /t/, the fricative noise of /s/, and F1/F2 values of the schwa in "the" were measured. The results show that 1) in the CV context, VOT durations, not fricative noise, were significantly shorter before /i/ than /æ/, in the production of Korean natives with a higher level of English proficiency (bilinguals) and native English speakers (NE), but native Korean subjects with a low level of English proficiency (NK) didn"t show any significant differences; 2) in the VCV context, the F1 values were higher before /æ/ than /i/ or /u/ for bilinguals and NE, while there was no such difference in the results of NK. The results for the F2 values showed similar patterns between NK vs. bilinguals and NE. These findings show that even the CV as well as V-to-V coarticulations cam be learned. The present study only partly supports Repp (1986) by showing that both CV and V-to-V coarticulations are acquired through learning, but it directly supports Kingston and Diehl (1994) in that even low-level phonetic details such as CV coarticulation are learned.

The Role of Awareness in Korean L2 Learners

한정임(Jeong-Im Han),황종배(Jong-Bai Hwang) 한국외국어교육학회 2003 Foreign languages education Vol.10 No.3

This study explores the role of awareness in L2 learning through investigating Korean EFL learners' perception of optional epenthetic stops in English. Stop epenthesis is a language-specific phonetic variation which is hard for even native speakers to perceive and is never consciously taught or learned in the environment of English language teaching situation of Korea. One native speaker of English produced phonotactically possible English nonwords containing the environment for stop epenthesis in which three nasals /m, n, η/ and a lateral /l/ are followed by each of the sibilants /s, θ, f/. It was revealed that epenthetic stops occurred between nasals and sibilants, but that there was no stop insertion after the laterals. Two proficiency groups (high vs. low) of Korean learners of English were asked to listen to the native speaker's recording and detect any target stops within the test words to see if they perceive the epenthetic stops spoken by the native speaker. There existed a significant group difference in the perception of epenthetic stops, which means that Korean EFL learners improve their ability to perceive English epenthetic stops as their overall English proficiency grows. considering that Korean EFL learners received no formal instruction and they were never aware of the presence of epenthetic stops, the dissociation of L2 learning and awareness is supported from the present study.

최종열처리와 용접이Zircaloy-4의 방사선조사 성장에 미치는 영향을 조사하였다. 본 연구에서는 중성자 조사에 대한 모의시험으로 3.5MeV로 가속된 양심자 빔을 조사량 9.8 ${\times}{10^{21}}$p/$m^2$까지 시편에 조사하였다. 본 연구에 사용된 시편중znnealed 시편의 방사선조사성장이 가장 컸으며 ${\beta}$-quenched 시편의 방사선조사 성장이 제일 작았다. 방사선조사 성장의 크기는 용접을 함에 따라 감소하였다. 최종열처리 조건의 차이에 의한 방사선조사 성장크기에서의 차이와 용접이 방사선조사 성장에 미치는 영향을 ray 회절시험으로부터 계산된 Kearns number, f,를 이용하여 정량적으로 분석하였다. Abstract The effect of final heat treatment and welding on the irradiation growth of Zircaloy-4 was investigated. As a simulation for neurtron irradiation, accelerated proton beam with the energy of 3.5MeV was used up to the proton fluence of 9.8 ${\times}{10^{21}}$p/$m^2$ in the present study. It was found that irradiation growth of the annealed specimen was the highest and that of the ${\beta}$-quenched specimen was the samllest among the present specimens. The magnitude of irradiation growth of the present specimens decreased by welding. The difference in the magnitude of irradiation growth of the present specimens with different final heat treatment and the effect of welding on it were quantitatively analyzed in terms of crystallographic texture by using Kearns number, f, which was calculated from the x-ray diffraction data.

한국어 초성 비음의 인식 자질

강현숙 ( Hyunsook Kang ),한정임 ( Jeong-im Han ) 아시아문화학술원 2019 인문사회 21 Vol.10 No.1

본 연구는 비음과 모음 연결구간이 한국어 비자음을 인식하는데 기여하는 역할에 대해 연구하였다. 긴 비음 [ㄴ]과 짧은 비음 [ㄴ], 그리고 모음 [우]/[아]가 사용된 자연발화를 이용하여 세가지 타입(비성자질, 모음연결구간, 전체음절)의 음성테스트 시료를 만들었다. 실험결과에 따르면, 긴 비성자질과는 달리 짧은 비성자질은 비자음으로 인식되는 자질로는 약하다는 사실이 발견되었다. 짧은 비성자질은 폐쇄음으로 인식되기도 했다. 반면에, 긴 비성자질 뒤의 모음 [아]보다는 짧은 비성자질 뒤의 모음 [아]에서 비자음 [ㄴ]이 더 많이 인식되었다. 우리는 이런 현상이 비성자질과 연결모음구간의 상대적 돋들림에 의한 상호 보완작용 때문이라고 주장한다. 또한 이 논문은 [아] 모음 연결구간이 [우] 모음 연결구간과는 다른 인식결과를 도출하였다는 것을 보여주었다. 앞으로의 연구에서는 한국어의 다양한 비음과 모음과의 결합을 연구하려고 한다. This study investigated the role of the nasal murmur and vowel transitions as perceptual cues for Korean nasals. Three types of stimuli (murmur, vowel transition, and whole syllable) were generated from natural utterances of [n] with long vs. short murmur plus [u]/[a]. The results of the identification test showed that unlike the long murmur, the short murmur provides a weak perceptual cue for nasality. The short murmur could lead to the perception of nasals as voiced plosives. In contrast, more correct nasals responses were induced from the vowel [a] following the short murmur type rather than from the vowel [a] following the long murmur type. We suggest that there is the reciprocal relationship in perception between the relative salience of murmur and vowel transition. In this paper, we also showed that transition to vowel /a/ induced different perceptual results from transition to vowel /u/ did. In the future study, we will investigate a wide variety of nasals and the following vowel types to understand the full spectrum of the nasal-vowel sequence in Korean.
