This paper is intended to suggest how to improve Korean high school students' awareness of the pronunciation in order to foster communicative effectiveness. Initially it is focused on the tasks of listening to the suprasegmental aspects. The strategies used in the listening process are (1)discerning intonation units, (2)recognizing rhythm pattern, and (3)identifying contraction and linking in connected speech. The tasks including in each process are listening discrimination, guided practice activity, and listening and speaking activity. The teacher should avoid methods which yield discouraging outcomes and try to help students enjoy experience of success in doing exercises and activities. So I suggested: students put the slash on the pause perceptible to chunk the stream of speech into the intonation units, and mark the content words to internalize English rhythm. And then I suggested that students listen to pop song English in order to improve the awareness of function words and connected speech in the intonation unit.

This research mainly focuses on intonational characteristics of synchronous English speech. Intonation contours were extracted from 1,848 utterances produced in two different speaking modes (solo vs. synchronous) by 28 (12 women and 16 men) native speakers of English. Synchronous speech is found to be slower than solo speech. Women are found to speak slower than men. The effect size of speech rate caused by different speaking modes is greater than gender differences. However, there is no interaction between the two factors (speaking modes vs. gender differences) in terms of speech rate. Analysis of pitch point features has it that synchronous speech has smaller Pt (pitch point movement time), Pr (pitch point pitch range), Ps (pitch point slope) and Pd (pitch point distance) than solo speech. There is no interaction between the two factors (speaking modes vs. gender differences) in terms of pitch point features. Analysis of sentence level features reveals that synchronous speech has smaller Sr (sentence level pitch range), Ss (sentence slope), MaxNr (normalized maximum pitch) and MinNr (normalized minimum pitch) but greater Min (minimum pitch) and Sd (sentence duration) than solo speech. It is also shown that the higher the Mid (median pitch), the MaxNr and the MinNr in solo speaking mode, the more they are reduced in synchronous speaking mode. Max, Min and Mid show greater speaker discriminability than other features.

An intonation curve stylization was used for an acoustical analysis of English speech. For the analysis, acoustical feature values were extracted from 1,848 utterances produced with normal and fast speech rate by 28 (12 women and 16 men) native speakers of English. Men are found to speak faster than women at normal speech rate but no difference is found between genders at fast speech rate. Analysis of pitch point features has it that fast speech has greater Pt (pitch point movement time), Pr (pitch point pitch range), and Pd (pitch point distance) but smaller Ps (pitch point slope) than normal speech. Men show greater Pt, Pr, and Pd than women. Analysis of sentence level features reveals that fast speech has smaller Sr (sentence level pitch range), Sd (sentence duration), and Max (maximum pitch) but greater Ss (sentence slope) than normal speech. Women show greater Sr, Ss, Sp (pitch difference between the first pitch point and the last), Sd, MaxNr (normalized Max), and MinNr (normalized Min) than men. As speech rate increases, women speak with greater Ss and Sr than men.

Deaccentuation' means the phenomenon that the accent on the particular element which deserves to be accented, disappears and loses the property of intonational prominence. Based on some theoretical background, we divided the cases where deaccentuation can be placed into six categories : the first, the case that the words already mentioned are repeated in the context; the second, the case that the element can be recovered anaphorically or situationally; the third, the case that the elements are semantically weightless; the fourth, the case that the meaning of the word is empty; the fifth, the case that the elements are less informative, so that they are easy to predict; the sixth, the case that the elements are located after the focused words. Then we organized the context and the experimental sentences corresponding to each category. The utterances of Korean and English native speakers were recorded and analysed based on the ToBI system and compared to each other, in order to find out that Korean speakers can distinguish the difference within each sentence pair, and produce them with appropriate intonation similar to that of native speakers.

For the learners of English as a foreign language, oral repetition of model sentences is an e essential practice to improve their listening and speaking abilities of English. Skill training of both speech perception and production is involved in this practice. This paper reports on an observation of production e$\pi$ors in such practice made by Japanese college students in my class. The teaching material used is intended for acquainting the learners with basic English rhythm and intonation p patterns. The students were required to repeat each sentence in a series of conversations after a model reading. Although the vocabulary and expressions were rather limited, I monitored different kinds of errors in their repetition. Putting aside intonation, their difficulties are classified into five types; 1. Omission of words or morphemes, 2. Addition of unnecessary words or morphemes, 3. Replacement of words, 4. Japanization of English sounds, 5. Wrong rhythm caused by improper stress assignment. Accurate listening, especially to weakly stressed syllables and to assimilated sounds, as has often been pointed out, is the most difficult part in perception for them. Japanese sound system interferes in production of English sounds. More often than not their knowledge of grammar or the context does not work at all to guess the words they are hearing

The purpose of the study is to examine intonation patterns of cochlear implanted children compared with those of normal hearing children. The data tokens of three normal and five cochlear implanted children were collected and investigated. Their intonation patterns were analyzed using the speech analysis tool, Praat. The characteristics of the two utterance types, interrogative and declarative, were investigated. No significant difference in intonation patterns between the two subject groups was found. However, the general pitch of cochlear implanted children was higher than that of normal hearing children. In addition, cochlear implanted children showed frequent pitch breaks.

This paper reports the results of an experimental phonetic study of intonation contrasts perception by speakers of British English, Japanese and Russian. Six series of re-synthesized two-syllable rise-fall contours with manipulated parameters of the rise in the first and the fall in the second syllable were employed in the experiment. Modifications of pitch height were executed in 2 st steps, and of duration in 30ms steps. The subjects, who were native speakers of British English, Japanese and Russian, identified the sentence type of presented re-synthesized stimuli. The results of the experiments demonstrate overall similarity of the perception strategies across the three groups of subjects, especially regarding the thresholds of declarative' sentence type judgement. Non-declarative judgements are more language-specific. The results can be employed for the teaching of English, Japanese and Russian as foreign languages as well as for speech synthesis and recognition.

Six series of re-synthesized two-syllable rise-fall contours with manipulated parameters of the rise in the first and the fall in the second syllable were employed in the experiment. Modifications of pitch height were executed in 2 st steps, and of duration - in 30ms steps. The subjects, who were native speakers of British English, Japanese and Russian, identified the sentence type of presented re-synthesized stimuli. The results of the experiments demonstrate overall similarity of the perception strategies across the three groups of subjects, especially regarding the thresholds of 'declarative' sentence type judgement. Non-declarative judgements are more language-specific. The results can be employed for the teaching of English, Japanese and Russian as foreign languages as well as for speech synthesis and recognition.

Intonation as suprasegmental phonetic features conveys meanings on the postlexical or utterance level in a linguistically structured way. It includes three aspects: tunes, relative prominence, and intonational phrasing. In this article, I will treat how prosodic phrasing is functionally related to the listening comprehension of English by analysing the students' errors of listening comprehension. When utterance meaning is conveyed, it is realized to be divided into intonational phrases. The small intonational phrase is regarded as an intermediate phrase which has a primary accent and a phrase tone or audible break. Most students' errors of listening occurred with linking pronunciation in the intermediate phrases of the fast speech. Thus through the smallest unit with tune we can help students improve their pronunciation and listening ability of English.

This paper aims to compare and analyse the pattern of the pitch accent realization between the English native speakers and the .Korean speakers, using the sentences by the scope of focus including intransitive verbs; unaccusative, unergative, and passive, based on the previous studies. The results show that the English native speakers produce the intonational patterns similar to the previous study (Hoskins, 1996), which showed that English native speakers deaccented after the focused word for unaccusative and passive verbs in broad focus. Korean speakers, however, have a tendency not to deaccent after the focused word for both verbs. In the narrow subject focus condition, Koreans do not deaccent the verbs after the focused subject. In the narrow verb focus condition, they produce the pitch accent on verbs as the English native speakers do, but they tend to produce the pitch accent on subjects that should not be given any pitch accent. Therefore, unlike the English native speakers, the Korean speakers have a tendency not only that they do not produce three types of intransitive verbs with proper intonation, but also that they do not realize the focus structure itself properly.
