The aim of this paper is to measure the duration of Japanese 'sokuon' [t/k] and 'haneruon' [m/n] produced by Korean and Japanese native speakers. It was shown that in the case of Korean speakers, the duration of geminate of 'sokuon' was 1.5 times longer than that of a single consonant, whereas in the case of Japanese speakers, it was 2 times longer. The difference between Korean and Japanese prosodic structures appears to affect the perception and acquisition of a foreign rhythmic patternm non-existent in the speaker's native tongue. The duration of geminate of [s] was 2 times as long as a single consonant in both Korean and Japanese speakers' production. On the average, the duration of Japanese 'sokuon' [t/k/s] was 1.7 times longer than that of a single consonant in Korean speakers' pronunciation, whereas 2 times longer in Japanese speakers' pronunciation. The production of 'haneruon' by either Korean or Japanese speakers yielded a similar result to 'sokoun': 1) geminates lasted longer than a single consonant; 2) single [m] is longer than single [n]: 3) geminate of [n] is 3 times as long as single [n], whereas geminate of [m] is 2 times as long as single [m].

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.
