The purpose of this study is to analyse prosodic characteristics of accentual phrases (AP, hereafter) produced by Chinese learners of Korean in Korean text reading. The study is restricted only to the initial APs. Subjects are students who have been studying Korean at a beginner level. The results showed that Chinese learners of Korean tended to make errors in the realization of the tonal patterns of the initial 2 syllables of the initial APs. Also they showed different F0 slopes across the initial and second syllables in the initial APs. Chinese learners of Korean, therefore, need to focus on the prosodic characteristics of the initial 2 syllables of Korean APs to realize fluent Korean intonation.

The purpose of this study was to provide preliminary data on the acoustical differences of one syllable words spoken by speakers with different language backgrounds. 20 native speakers of Korean and English were asked to read 7 one-syllable words written in their native language. The phonetic and phonemic characteristics of 7 words were similar between two languages. The ratio of duration of the body (onset+nucleus) and the rhyme(nucleus+coda) relative to the duration of each syllable were calculated using CSL (Computerized Speech Laboratory). The results corresponds to the body-coda structure of the Korean syllable which is supported by the recent experimental psychological studies. More acoustic studies on the Korean syllable structure are required to establish clinical foundation for the phonological awareness and the reading intervention programs.

This experimental study aims to find out the correlation between semantic predictability and pitch-accent realization. For the experiment, we classified the predictability into three degrees: unpredictable, implicitly predictable, and explicitly predictable. And then each degree divided into to two subcatergories: one is adverbs/adverbial phrases of time or place and the other one is not time or place adverbs/adverbial phrases. The materials used in the experiment were 9 sentences for the each subcategory. One male and one female English native speakers participated in this experiment. Their reading speeches were recorded on Digital Audio Tape. Their speech data were analyzed by using Pitchworks program. The results of this experiment show pitch accented ratio is somewhat in inverse proportion to the degree of predictability.

In this paper I will examine some concrete examples of the obstacles faced by non-native speakers of Japanese when learning the language. I will go on to suggest ways in which these obstacles may be overcome. Nowadays there are numerous Japanese language books available for non-native speakers. However, most of these introductory Japanese language books focus on topics such as pronunciation, accent and intonation. Notable, these introductory textbooks provide insufficient emphasis on prosodic features of the Japanese language. The Japanese language has been considered by many teachers as relatively easy compared to other languages, due to its simple phonetic structure. This may be a partial explanation of the reason why the teaching of prosodic features has generally been given insufficient emphasis. To teach Japanese efficiently at a university level I have combined an emphasis on the teaching of prosodic features together with my experience of television announcing. This has entailed using television news programmes and contemporary reading materials in my class. Using taped material I intend to describe a case-study of teaching of Japanese articulation.

The purpose of this study is to examine the pitch pattern of Korean accentual phrases produced by Chinese Korean-learners in the reading of a Korean text. Korean accentual phrase is determined by a specific F0 contour. And the pitch contour of APs differ depending on their length and the nature of initial segment. In order to examine if Chinese speakers are also aware such a phonetic properties, we have examined the AP pitch contours produced by 15 Chinese speakers differing in proficiency, and compared them to pitch contours produced by six Korean native speakers. The results show that Chinese speakers' pitch errors were observed in initial segment-tone interaction and in type of pitch patterns. However, even though Chines speakers produced the same type of pitch patterns, internal tonal modulation differs from native speakers. Finally, on the basis of theses results, we proposed a teaching method that visualizes the F0 contour.

This study aims to clarify disfluency loci in a neurogenic stuttering group and to examine how the characteristics are different from a developmental stuttering group. For the study, spoken language samples were collected from 11 adults with developmental stuttering and 11 adults with neurogenic stuttering in the course of speaking tasks including reading, monologue and conversation. Using the collected samples, disfluency characteristics of the two groups were to be investigated by analyzing adaptation effect, consistency effect and frequency of disfluency occurrence according to word position, which are related to the occurrence loci of disfluency. Results of this study were as follows: First, while the neurogenic stuttering group did not show any adaptation effect, the developmental stuttering group showed the adaptation effect that the percent of disfluency word reducing as they read the same materials repeatedly. Second, there was no meaningful difference of consistency effect between the two stuttering groups. Third, the neurogenic stuttering group showed more disfluency frequency in final sounds among the word position compared to the developmental stuttering group.

Dysphonia is well known as one of the otolaryngological symptoms of coronavirus disease 2019 (COVID-19) infection. The vocal changes of the COVID-19 condition have been reported in terms of parameters of multi-dimensional voice assessment, including acoustic analysis, auditory-perceptual evaluation, and psychometric assessment. However, there has not been a daily followup study in patients with acute COVID-19 infection. In this study, a 41-year-old male performed daily voice recordings of vowel phonation and passage-reading tasks during the self-quarantine period of one week. Compared to the normal voice status of the prepandemic period, voice abnormalities peaked on day two after the diagnosis of COVID-19 infection and recovered after one week.

This paper investigates the English intonation of Korean speakers of English as a second language and compares it to that of English native speakers. The speech data of ten Korean speakers and three native speaker controls were tape recorded in an oral reading task in which the subjects were asked to read aloud the given text which was used in the study of Wennerstrom (1994). Following Pierrehumbert and Hirschberg (1990) who distinguishes the discrete units of meaning in intonation, pitch accents, phrase accents and boundary tones were measured. It was found that Korean speakers' use of phrase accents and boundary tones were relatively good compared to their use of pitch accents. That is, Korean speakers conform to native speakers' use of phrase or boundary tones for the purpose of marking the relationship between intermediate or intonational phrases. In contrast, the main difference of Korean speakers' use of intonation from that of native speakers was the use of pitch accents. That is, Korean speakers tend to have difficulty in assigning an appropriate pitch accent to signal relationships between new or contrastive information and that which is assumed to be understood or contributes little to the meaning of the utterance.

The existence and the extent of vowel length difference before voiced/voiceless consonants in English and Korean are examined in three groups: (1) Korean-speaking Americans (group A), (2) immigrants who moved to the U.S. in their early teens (group I), and (3) Koreans who have been in the U.S. for less than 3 years (group K). 14 subjects were recorded reading 10 English and 10 Korean sentences. The results show that the three groups exhibit different patterns of the vowel length difference: Group A shows a very strong tendency of vowel lengthening before voiced consonants in both English and Korean, while Group I shows less degree of vowel lengthening, and Group K shows almost no tendency of vowel length difference in both languages. This strongly suggests that, (1) unlike English, Korean does not have the vowel length difference depending on the following consonants, and (2) the vowel lengthening effect observed in Korean (L2) speech in group A may be the result of transfer of the phonetic trait acquired in English (L1). It also implies that, in teaching pronunciation, some facts such as the vowel length difference cannot be expected to be acquired automatically for the learners of English, but have to be taught explicitly.
