This study is concerned with the educational program Visual Analysis Tool (VAT) for sound development for foreign intonation using personal computer. The VAT can run on IBM-PC 386 compatible or higher. It shows the spectrogram, waveform, intensity and the pitch contour. The system can work freely on either waveform zoom in-out or the documentation of measured value. In this paper, intensity and pitch contour information were used. Twelve French sentences were recorded from a French conversational tape. And three Korean participated in this study. They spoke out twelve sentences repeatly and trid to make the same pitch contour - by visually matching their pitcgh contour to the native speaker's. A sentences were recorded again when the participants themselves became familiar with intonation, intensity and pauses. The difference of pitch contour(rising or falling), pitch value, energy, total duration of sentences and the boundary of rhythmic group between native speaker's and theirs before and after training were compared. The results were as following: 1) In a declarative sentence: a native speaker's general pitch contour falls at the end of sentences. But the participant's pitch contours were flat before training. 2) In an interrogative: the native speaker made his pitch contours it rise at the end of sentences with the exception of wh-questions (qu'est-ce que) and a pitch value varied a greath. In the interrogative 'S + V' form sentences, we found the pitch contour rose higher in comparison to other sentences and it varied a great deal. 3) In an exclamatory sentence: the pitch contour looked like a shape of a mountain. But the participants could not make it fall before or after training.

The purpose of this work is to examine the viability of employing the prosody cloning technique in teaching English prosody. Ten native speakers of Korean high school students with similar level of English proficiency participated in the poem self-study experiment. Five of them were grouped into the experimental group and the remaining five into the control group. One popular English poem from a high school textbook was selected and its recording by a professional native speaker of English was used in the experiment. The members of the two groups made a recording of the poem both before and after the experiment. For the study material, the experimental group used their own recorded utterances with their prosody cloned from the professional English speaker, while the control group used the utterances of the professional speaker alone. The acoustic analysis of the recordings by the prosodic foot both before and after the experiment showed that the experimental group performed slightly better than the control group in the realization of the intensity contour of the poem. There were no significant differences in the realization of the intonation contour and segmental durations between the two groups. The recording after the experiment was also subjectively evaluated by a native speaker of English and the scores for the experimental group were slightly higher than the control group. These findings suggest that the use of English poems with the help of the prosody cloning technique is a potentially viable approach to teaching English intonation to high school students. A long-term study with more students is necessary.

The focus of this study was to investigate whether there is a position effect on identification accuracy of L2 consonants by Korean listeners and to examine how Korean listeners perceive the phonetic properties of initial and final consonants produced by a Korean learner of English and an English native speaker. Most studies examining L2 learners' perception of L2 sounds have focused on the segmental level but very few studies have examined the role of prosodic position in L2 learners' perception. In the present study, an identification test was conducted for English consonants /p, t, k, f, ɵ, s, ʃ/ in CVC prosodic structures. The results revealed that Korean listeners identified syllable-initial consonants more accurately than syllable-final consonants. The perceptual accuracy in syllable initial consonants may be attributable to the enhanced phonetic properties in the initial consonants. A significant correlation was found between error rates and F2 onset/offset for stops and fricatives, and between perceptual accuracy and RMS burst energy for stops. However, the identification error patterns were found to be different across consonant types and between the different language speakers. In the final position, Korean listeners had difficulty in identifying /p/, /f/, /ɵ/, and /s/ when they were produced by a Korean speaker and showed more errors in /p/, /t/, /f/, /ɵ/, and /s/ when they were spoken by an English native speaker. Comparing to the perception of English consonants spoken by a Korean speaker, greater error rates and diverse error patterns were found in the perception of consonants produced by an English native speaker. The present study provides the evidence that prosodic position plays a crucial role in the perception of L2 segments.

The purpose of this study is to measure the impact of Korean speakers' English stop pronunciation on their general pronunciation proficiency. For these purposes, 20 Korean speakers read English sentences and their pronunciations were rated by native English speakers. The Korean speakers' VOT values of English stops in sentences were then measured and the relation between the VOT values and native speakers' pronunciation rating was compared. Here, the relation between (1) the proficiency score of each speaker and VOT values; and (2) the proficiency score of each sentence and VOT values were analyzed. The results show that there is a relation between the proficiency score of each sentence and VOT values of /t, b, d, g/; and there is a relation between VOT values of /t, b, d, g/ and proficiency scores of each speaker while these is a weak relation between VOT values of /p, k/ and proficiency scores of each speaker.

The purpose of this study is to investigate the English pronunciation for high-leveled adult Korean speakers based on pronunciation proficiency test. For this purpose, one native English speaker and eight Korean speakers' suprasegmental features such as sentence F0, standard deviation of vowels and stressed / unstressed vowels' F0, duration and intensity were measured and analyzed. The major results show that (1) high-leveled adult Korean speakers' sentence F0 was similar to that of native English speaker, (2) vowel durations, were less diverse than those of native English speakers, and (3) high-leveled adult Korean speakers utilize vowel duration more actively than F0 to indicate the stress assignment of vowels.

This paper investigates the phatic function of intonation in Russian by recording and analysing 11 female native speakers of standard Moscow Russian. This paper shows that differences in intonation pattern of a sentence are associated with differences in degree of listener's involvement in the speech. Intonation pattern of an utterance having phatic function appears to be determined by 1) the speaker's readiness to talk to evoke the listener's attention ; 2) the speaker's intention to continue the communication. Some emphasis is placed on the relationship between intonation pattern of an utterance and speaker-listener interaction.

This paper is to introduce 'Dr. Speaking', which was recently developed by Eonon Inc.. 'Dr. Speaking' is an English pronunciation tutoring system. This has three distinguishing features. First, it teaches how to organize a speaker's vocal organs to pronounce accurately. Second, after it compares a speaker's pronunciation with that of a native speaker's, it grades that speaker's pronunciation level according to phonetic standards. Third, it provides proper information necessary for correcting a speaker's incorrect pronunciation. It is not always easy for a tutoring system to execute the above three almost simutaneously. However, 'Dr. Speaking' proved itself that it is possible by adding speech technology (e.g. speech recognition) to phonetic knowledge.

The aim of this study is to find out how the labiovelar onglide /w/ in English kwV sequences that have minimal pairs with kV sequences is pronounced differently among Korean EFL learners based on acoustic evidence. This study tries to identify /w/ sound in English kwV sequences through spectrograms and to examine the duration ratios of each segment in kwV words to compare the patterns of an English native speaker with those of Korean speakers of English. In spectrographic analyses, the complete deletion of /w/ and partial pronunciation of /w/ dubbed [$k^{w}$] were identified as well as the targetappropriate production of /w/. The general production patterns with respect to the duration ratios in English [kw] sequence words showed that the subjects who produced /w/ had similar ratio patterns that the native speaker had in that the vowel duration ratio in kwV sequences was shorter than that in kV sequences. By contrast, the subjects who deleted [w] had a long ratio of the onset [$k^{h}$] while the speaker with a partial pronunciation of /w/ had a long ratio of the following vowel.

This research is exploratory in considering the unique socio-cultural context of South Korea, where the present government is responding to the demand for English language training. The study asked the question: What do mothers experience when sending their young children to a private English institute, so called English kindergarten, instead of a regular preschool? A qualitative approach was used to analyze the in-depth interviews with 19 mothers who sent their young child to an English kindergarten. Mothers stated that their young child needs to be a competent English speaker. The mothers expected that an English kindergarten would prepare their child better for the elementary school English curriculum than a regular preschool. The study revealed that English kindergartens symbolized the precedence and the privileges of the elite because of their high tuition fees, native-speaker teachers, and small class sizes. The mothers showed a sense of pride and vicarious satisfaction from sending their child to an English kindergarten. However, the mothers recognized that English kindergartens put more emphasis on cognitive learning instead of the social development of children. It was almost impossible for mothers to communicate with the native-speaker teachers about their child. The mothers seemed to overlook their child's struggle to adapt to an English Kindergarten. The findings of the study raise issues concerning the boom of teaching young children English in Korea.
