This study investigated the articulatory characteristics of Korean singleton and geminate sonorants in the word-medial position, effects of the duration of the sonorant consonant and the preceding vowel on perception, and the difference between native Korean speakers and foreign learners of Korean in perceiving the singleton and geminate consonant contrast. The Korean sonorant consonants(/m, n, l/) are examined from the VCCV, VCV sequences through speech production and perception experiments. The results suggest that the duration of the sonorant consonant is the most important factor for native Korean speakers to recognize whether sonorants are overlapped, and the duration of preceding vowel and other factors affect the recognition of singleton/geminate consonant contrast if the duration is not obvious. A perception experiment showed Chinese Korean language learners did not clearly distinguish singleton consonants from geminate consonants. The results of this study provide basic data for recognition of singleton/geminate consonant contrast in word-medial of Korean language, and can be utilized for teaching Korean pronunciation as a foreign language.

In the literature on the tense consonants in Korean, it has been proposed that this consonant is underlyingly represented by a single consonant (the singleton hypothesis) and that it is represented by a sequence of two lenis consonants (the geminate hypothesis). One piece of the empirical evidence supporting the geminate hypothesis is that the closure duration of tense consonants in intervocalic position is more than twice as long in comparison with their lenis counterparts. In this paper, we report on the closure duration of three types of plosives in various phonotactically permitted contexts in Korean. The results of the measurement show that the duration of the tense consonants in post-sonorant contexts is reduced by a third in comparison with that of the intervocalic ones. These temporal differences suggest that the measurement of closure durations in intervocalic position alone is not sufficient to sustain the geminate hypothesis.

The current study focused on the production of geminate nasal consonants across different word boundary types in Korean as a function of speech style to investigate whether temporal properties are preserved across varying speaking rates. Assimilated geminates in Korean, known as true geminates, are produced with distinctively longer consonant duration compared to singletons. Despite a large body of literature for geminates across different languages, geminates in Korean have been relatively less investigated with respect to the durational patterns in relative terms and temporal variabilities. In this study, singletons, word-internal geminates and word-boundary (fake) geminates produced by ten native Seoul Korean speakers were compared in terms of absolute consonant closure duration, preceding vowel duration, the relative ratios (consonant-to-preceding vowel duration) as well as the temporal variabilities in speech production. The results showed that word-internal geminates were produced with longer consonant duration and greater temporal variabilities than singletons and word-boundary geminates in absolute duration, indicating relatively greater flexibility in timing. However, only word-internal geminates were produced with distinctively longer consonant duration with significantly lower variability in relative duration regardless of speech styles. The results provide some insight into the representation of temporal information in the production of Korean geminate consonants.

The aim of this paper is to investigate Japanese speakers' perception of Korean tense consonants. In a range of perceptual experiments Japanese participants were directed to label Korean stimuli using Japanese katakana characters. The analysis of the results showed a strong influence of Japanese phonology in the responses. Japanese perception of sokuon was increased, (1) when the tense consonants were in word medial position, (2) when tense consonants were other than /s/, (3) when the tense consonant followed voiceless consonants, (4) when the consonants were part of a cluster sharing their point of articulation, (5) when preceding vowel were other than /u/, (6) when following vowel were /u/. This result, showing preference for phonology, is in harmony with previous research on the Japanese sokuon perception using Japanese (Takeyasu 2009, Matsui 2011), and Italian (Tanaka & Kubozono 2008) stimuli.

영어와 한국어의 차이점 중의 하나는 한국어에서는 똑같은 자음이 앞 음절의 종성과 뒤 음절의 초성으로 나와서 겹자음이 될 수 있으나 영어에서는 이것이 불가능하다는 것이다. 그러므로 영어를 배우는 한국 학생들은 영어에서 summer와 같이 겹자음 철자를 포함하는 단어들을 발음할 때 철자의 겹자음을 모두 발음하는 오류를 흔히 보인다. 따라서 본 예비 연구에서는 한국 학생들이 영어 겹자음 철자를 어떻게 발음할 뿐 만 아니라 인지하는지 살펴보기 위해서 영어 겹자음과 단자음의 유사 최소변별쌍으로 구성된 36개의 실제어를 20명의 대학생이 듣고 발음하는 인지와 발화 실험을 실행하였다. 실험 결과 한국 학생들은 단자음 철자를 인지하거나 발화할 때는 각각 78.6%와 76.1%의 비교적 높은 정확율을 보이는 반면에 겹자음 철자을 인지하거나 발화할 때는 각각 55.3%와 61.7%의 낮은 정확율을 보임으로써, 영어 겹자음 철자를 더 길게 인지하고 또한 더 길게 발음하는 오류를 보였다. 또한 한국학생들의 발화를 스펙트로그램을 통해서 분석함으로써 영어 단자음 철자보다는 겹자음 철자에서 더 많은 발화오류를 일으키는 것도 보여주었다.

한국어에서는 모음사이에서 겹자음이 나타날 수 있으나 영어에서는 이것이 불가능하므로 영어를 배우는 한국 학생들이 $su\underline{mm}er$와 같이 겹자음 철자를 포함하는 단어들을 발음할 때 철자의 겹자음을 모두 발음하는 오류를 흔히 범한다. 따라서 본 파일럿 연구에서는 한국 학생들이 영어 겹자음 철자를 어떻게 발음하고 인지하는지 살펴보기 위해서 영어 겹자음과 단자음의 (유사) 최소변별쌍으로 구성된 36개의 실제어를 20명의 대학생이 듣고 발음하는 인지와 발화 실험을 실행하였다. 실험 결과 한국 학생들은 철자의 영향으로 영어 단자음 철자 단어를 발음할 때보다 겹자음 철자 단어를 발음할 때 이중으로 길게 발음하는 오류를 더 흔히 범해서 겹자음 철자 단어의 정확율보다 단자음의 정확율이 크게 높았으며, 인지의 경우에도 마찬가지로 단자음 철자 단어의 인지 정확율이 겹자음 철자보다 확연하게 높았다. 덧붙여, 한국 학생들의 영어 유성 파열음의 발화 오류율이 낮은 이유를 한국어 음운 체계의 전이로 설명하였다. 끝으로, 한국학생들의 발화를 스펙트로그램을 통해서 분석함으로써 영어 단자음 철자보다는 겹자음 철자에서 더 많은 발화오류를 일으키는 것도 보여주었고 또한 교육적인 함축점도 제안하였다.

Korean fortis consonant is not included in the consonantal inventory, but a result of phonetic implementation at the phonetic level, P. With the framework of Cognitive Phonology, a construction of Post Obstruent Tensification is proposed in such a way that rule-ordering is eliminated. This enables us to overcome methodological problems raised in former analyses of fortis under geminate hypothesis, and give a uniform account for three categories of fortis consonants. By assuming extrasyllabicity of verb-stem-final, consonant neutralization of fortis in the coda position is explained by the invisibility at the P-level. and, therefore. modification of Coda Neutralization rule is called for.

The aim of this paper is to research on the actual condition of Koreans' Spanish consonants pronunciation with an emphasis on describing the phonetic different of Korean speakers and Spanish speakers. 40 Spanish words were chosen for the speech sampling, and 10 Spanish majoring Korean students from Seoul or Kyunggi Province and 3 Spanish speakers form Castile, Spain participated in the interview. The most noticeable phonetic differences of Korean speakers' pronunciation comparing with Spanish speakers are abstracted as follows: 1) The voiced stops are pronounced voiceless or weak voiced. 2) The voiced stops are slightly aspirated. 3) The length of voiceless consonants is quite longer than the length of proceeding vowel. 4) Fricatives and affricates are somewhat fronter, and weaker in the degree of friction. 5) There is a strong tendency to geminate dental lateral /l/ such as 'pelo' and to vocalize palatal lateral /$\rightthreetimes$/ such as 'calle' 6) Unlike in Spanish speech flap $\mid$r$\mid$ and trill [r] are pronounced similarly in Korean speech.
