How to teach intelligible, communicative pronunciation is a continuous question in the English education. Without good input, we can not expect good output. However, in EFL situation, it is very difficult to input the good English pronunciation, therefore, we have to find out the efficient and effective material for teaching pronunciation. One of the materials is song, because songs contain the linguistic and cultural traits of the language. The purpose of this paper is to clarify the reason why songs are good for teaching pronunciation. Koreans, who are syllable timed language users, have difficulties in English pronunciation of stress, rhythm, consonants cluster, linking or blending in connected speech. The 134 songs from wee sing are analyzed for how these traits show in songs. The result shows that we can acquire the traits easily and naturally through songs. And a lesson plan is offered as an example for teaching songs.

The purpose of this study was to investigate the different aspects of word-initial liquid sounds in Korean according to generations. Five women in their 50s and seven in their 20s participated in the experiment. We examined FL (formant of liquids) and voice sustained time by using Praat software. Three English native speakers were asked to judge the Korean speakers' recorded speech samples for marking [l] or [r] using evaluation sheet. The results of the two experiments revealed three important aspects. First, there was a statistically significant difference between the two groups in the FL of the words 'racket' and 'ruby.' Second, we found statistically significant differences in 'rhythm', 'ruby' and 'litter' from the measurement of the duration of the acoustic data. Third, there was no difference in pronunciation between the two groups according to the phonemes of the original language. The results of this study showed that it is difficult to say that the duration of word-initial liquids and the phoneme difference of the original language are indicators to distinguish the word-initial liquids between generations. Also, it was seen that the pronunciation of Korean word-initial liquid sounds varied across generations.

This study compared English and Korean speakers with regard to the nasalization of the English stops /b, d, g, p, t, k/before a nasal within and across a word boundary. Nine English and thirty Korean speakers participated in the experiment. We used 37 speech items with different grammatical structures. Overall the English informants rarely nasalized the stops while the Korean informants generally greatly nasalized them though widely varying from no nasalization to almost complete nasalization. In general, voiced stops were more likely to be nasalized than voiceless stops. Also, the alveolar stops /d, t/tended to be nasalized the most, the bilabial stops /b, p/ the second most, and the velar stops /g, k/ the least. Besides, the closer the grammatical relationship between neighboring words, the more likely the stop nasalization occurred. In contrast, the Korean syllabification - the addition of the vowel /i/ to the final stops - worked against the stop nasalization. On the other hand, different stress (accent) or rhythm effects of the two languages are assumed to contribute to the significantly different nasalization between English and Korean speakers. The spectrum of stop nasalization obtained from this study can be used as an index to measure how close a certain Korean speaker's stop nasalization is to English speakers'.

Hopkins의 도약률(Sprung Rhythm)은 영어의 운율자질인 강세에 의한 엄격한 정형률을 고수하고 있다. 즉 약강 5보격이나 약강 6보격의 정형률을 지킨다고 Hopkins는 주장한다. 일반 독자나 운율비평가는 이를 인정한다. 문제는 시인의 음량(quantity) 기준에 의하여 강, 약 자리를 어떻게 충족시키고 있느냐 하는 점이다. 모든 비평가는 Hopkins의 음량 기준의 지나친 편의성과 임의성, 및 응통성?에 대하여 그의 음량 이론을 수용하려하지 않는다. 그러나 Kiparsky는 Hopkins의 설명에 따라 시인의 도약률을 분석하면 시인의 음량 이론이 이유 있음을 설명해 보인다. Kiparsky의 분석에서 문제점은 없는가? 만약 있다면 그것은 바로 Hopkins의 음량이론의 문제점이 될 것이다. 이 연구에서는 Hopkins의 편지 속의 설명은 실제로 독자의 낭송 속에서 어떻게 실현될 것인가 즉 '귀로 듣고 감상(ear and taste)'할 때 나타날 리듬형, 즉 낭송의 틀에 의한 분석을 시도하였다. 그것은 도약률이야 말로 읽히기 위한 것이며 '보는 시'가 아니라는 전제에서이다. 여기에서는 낭송에서 나타날 도약률의 음량과 장단, 즉 지속시간을 하나의 '낭송보(Textsetting for Sprung Rhythm)'에서 투사해 보고자 했다. 그 낭송보는 Hayes & Kan(1994)의 '어린이의 민속노래 보(Textsetting for Children's Folk Songs)'를 원용하였다. 약강 4,5,6보격, 강약 4,5,6보격의 일정한 강세 모습과 일정한 지속시간을 보여주는 도약률의 '낭송보'는 다음과 같다('약'자리와 '강'자리의 간격은 일정하게 보고 '강'의 돋들림은 격자로 더 높게 표시하였다). 이와 같은 낭송보는 독자, 즉 낭송자의 낭송 가능 범위를 그려 준다. 즉 약자리의 두개나 그 이상의 음절을 한꺼번에 낭송할 수 있음을 보여 준다. 그 음은 자연히 연음(slurring)이 되기 마련이다. 그러므로 이 연구는 다음과 같은 사실을 규명해 준다. 첫째, 어떤 시행도 규칙적인 박으로 낭송된다. 둘째, 음량은 박자에 의하여 좌우된다. 즉 강과 약자리의 일정한 지속시간의 범위 내에서는 몇 개의 음절도 낭송이 가능하다. 그것은 일정한 간격의 자리를 나타내는 격자로 결정된다. 따라서 모라(morae)의 개념보다도 박자의 개념으로 도약률은 낭송된다. 셋째, 모든 약자리와 강자리는 일정한 간격과 실제의 박(묵박도 포함)에 의하여 규칙적이다. 넷째, 외율음보는 격자의 길이내에서 낭송된다. 그러나 이 연구의 기본은 시인과 독자의 율형(Metrical Pattern)에 대한 의식과 의도(intention)가 전제된다. 이것은 이 연구의 문제임과 동시에 장점이다. 시율의 분석은 보는 율형이 아니라 읽고 낭송하는 율형으로 분석되어야 함을 보여 준 것이 이 연구의 기여이다.

This paper aims to investigate the internal structure of the pre-nuclear intonation pattern and to discuss the inventory and usage of the phrasal tone in Korean based on the acoustic analysis of 80 test sentences. CSL Model 4300 was used for recording and filing, and Multi-speech Model 3700 for analysis. It is shown that the pre-nuclear intonation pattern is composed of one or more phrasal tones, the intonation pattern of the rhythm nit. It is observed that the second phrasal tone begins with a higher pitch than the first one and that the phrasal tones following the second one begins with a lower pitch than the preceding phrasal tone unless a certain word is emphasized. In addition to Level, Rising, Falling, and Rise-Fall phrasal tones already established in Lee (1990, 1991, 1996), Pall-Rise and Rise-Fall-Rise phrasal tones are newly established in this paper. It is observed that Rising and Rise-Fall-Rise phrasal tones are most frequently used as the first phrasal tone of a pre-nuclear intonation pattern and the falling tone as the last phrasal tone, and that Fall-Rise and level tones appear most frequently in the middle of a pre-nuclear intonation pattern.

This paper attempts to investigate the tonal implementations of English stress clash, arguing that a preceding stress shifts leftward when two lexical stresses conflict across word boundaries or that H* and L* pitch accents are alternatively manifested on the stressed syllables, establishing intonational peak and valley contours. We claim that the H*/L* alternation might be a tonal strategy to avoid stress clash, and that pitch could be solely manipulated to display a rhythmic effect with maintaining lexical stress. In the experiment, we examined two-word combinations whose boundaries involve stress clash, and divided them into two categories. One has the preceding words involving a heavy syllable ahead of stress to guarantee the place for a shifting stress and the other, a light syllable, in which case stress shift is completely prevented. We analyzed the distribution of pitch accents in the word combinations, focusing on the pitch configurations in the cases where stress should not be shifted. Results show that approximately 50% of the stimuli show stress shift in the heavy syllable combinations of the preceding words; the preceding stress is moved leftward within the word. The other 50% and the light syllable combinations show various pitch accents patterns; H* and L* alternation, deaccentuation of either stressed syllable, or L-insertion between two H* pitch accents, etc. We interpret this as a rhythmic effect of tone to avoid stress clash and suggest that a true stress clash would be confined into cases without H*/L* contours.

The phonetic study of English language in Japan is a matter of great importance, a problem of major concern and a. vital subject The special difficulties which the Japanese college students have in learning English lie in the field of prosodic features of English, such as, syllable, rhythm, stress, intonation, prominence, of.. These difficulties have made Japanese students' pronunciation relatively monotonous or mora(ness). In my presentation, the specific phonetic features of Japanese language first will be discussed and clarified. And then the effective teaching method of intonation to improve Japanese students' pronunciation will be suggested. Finally, the oral dialogue with intonation analysis and transcription in the class room will be demonstrated to highlight the presentation.

The aim of this paper is to show the possibilities of the proficiency -based and integrated teaching of High School English reading and listening based on sense group and utterance restructuring. The proficiency -based and integrated listening and reading activities in stages are as follows. Step1, students fill in the blanks with strong or weak sounding words according to their abilities. Step2, speak along (track) based on restructuring and post-lexical phenomena while listening to the sentence. Step3, read and understand directly the passage, which have been marked the differentiated places where a native speaker of English would beat all likely to pause. Students need to listen to spoken English, so they recognize words in written and spoken form. They must be familiar with suprasegmental features, stress and rhythm, and post-lexical phenomena during reading activities.

Music Summarization is to extract there presentative section of a song such as chorus or motif. In previous work, the length of music summarization was fixed, and the threshold to determine the chorus section was so sensitive that the tuning was needed. Also, the rapid change of rhythm or variation of sound effects make the chorus extraction errors. We suggest the linear regression for extracting the changeable length and for minimizing the effects of threshold variation. The experimental result shows that proposed method outperforms conventional one.
