The purpose of the present study was to evaluate the effect of 7-point interval scale(EAI) and visual analogue scale(VAS) on perceptual judgement and the reliability of severity on voice problems by dysphonic speakers. 30 undergraduate students studying communication disorder were enrolled in the perceptual evaluation. Those listeners judged overall voice severity within the anchored(condition 1) and non-anchored scales(condition 2) for vowel prolongation and reading tasks by 25 speakers with voice disorder. The results of this study showed that the scores by VAS was significantly higher than EAI in both condition 1 and condition 2 for vowel prolongation and reading task. However, the scores by EAI method was higher than by VAS method on voice severity of vowel prolongation (condition 1) and reading task(condition 2). These results suggest auditory-perceptual scaling procedures must be more studied in the aspects of clinical application of voice disorder.

The purpose of this study was to compare the vocal characteristics of 40 adults with and without cerebral palsy (CP), upon presentation of three speech tasks (i.e., reading, chanting, and singing). The Praat program was utilized to generate data on fundamental frequency, voice intensity, jitter, and shimmer. The results of the analysis revealed no significant differences on fundamental frequency and intensity. However, both groups showed significant decreases in jitter and shimmer when engaged in singing tasks. The analysis of group differences indicated that adults with CP showed significantly higher variation scores on jitter and shimmer than the group without CP, and the difference on jitter and shimmer became greater during rhythmic chanting. In terms of jitter variation, the interaction effects according to the groups and types of speech tasks were greater, demonstrating the differences between the two groups. This study can be utilized as a basic research, regarding changes in vocal characteristics of adults with CP according to different musical speech tasks.

This study aimed to compare the prosodic characteristics of North Korean defectors and South Koreans in three types of sentences (declarative, interrogative, and negative) in two reading tasks (short and dialogue) through acoustic analysis and auditory-perceptual evaluation. In addition, this study examined the relationship between the auditory-perceptual evaluation scores and self-assessment questionnaires on intonation for North Korean defectors. The participants were 15 North Korean defectors and 15 Korean speakers with standard Seoul accents. For statistical analysis, three-way mixed ANOVA and multivariate analysis were performed within the three types of sentences in the reading tasks through acoustic analysis and the Mann-Whitney U Test for auditory-perceptual evaluation. Pearson's product-moment correlation coefficients were also used to identify the correlations between the results of the self-assessment questionnaire on intonation and the auditory-perceptual evaluation. The North Korean defectors were found to have a significantly lower pitch range and auditory-perceptual evaluation score than South Koreans in reading tasks. Moreover, there was a significant correlation between their auditory-perceptual evaluations and self-assessment questionnaires on intonation. The study findings suggest that North Korean defectors, who face many challenges with intonation, showed a tendency to think that their intonation differed from the standard Korean intonation and showed better auditory evaluation results for interrogative sentences.

This study aims to define the isochronism of English feet. To assess the average value of moras of a foot, the study is, first, to set up a way of counting the number of the moras on the extrametricality with some modifications. Secondly, with the measurement of the average duration of feet of Shakespeare's 120 sonnets through Praat (version 4.030, 2002), it clarifies the foot isochronism in English. With the two ways of measuring the isochronism, it clarifies the fact the foot isochronism permits the difference scope of $2.2{\mu}'s$ (moras) to $1.8{\mu}'s$, that is, $22{\mu}'s$ to $18{\mu}'s$ per line, while the acoustic assessment shows the isochronically congnitive gap of 302-447msec. per foot, or 4,461msec. to 3,019msec. per line in case of iambic pentameter in English poetry.

The purpose of this paper is to examine the effect of using songs for the acquisition of English Prosody in elementary school. For the purpose, 8 classes were chosen to teach songs for four months, and listening tests and reading test were performed for analyzing the effect. The result is as follows : (1) The result of listening test showed that the average scores of the experimental classes were higher than those of comparative classes, and it was more effective in lower grades than in upper grades. (2) In pronunciation tests, the pronunciations of experimental classes were more similar to native speaker's pronunciation that those of comparative classes in intonation, lexical stress and sentence stress. (3) Singing songs repeatedly is more important than learning many songs. It means that to give the chances to sing as many times as possible is advisable for teaching pronunciation.

This study aims to define the isochronism of English feet. 275 feet, which consist of 66 lines of 13 poems written by 12 modem poets(The Poet Speaks, 1982), were used for analysis of durational measurement. To assess the average value of a foot, the study is, first, to set up a way of measuring the duration of each foot on its types in English meter. Secondly, with the measurement of the average duration of feet in modern poets' English poetries through Praat (version 4.119, 2003), it clarifies the foot isochronism in the fixed meter. With the two ways of measuring the isochronism, it clarifies the fact the foot isochronism permits the difference scope of the perceptive gap of 555.4-974.5msec. per foot in case of iambic meters in English poetry.

The recent growing popularity of statistical methods in machine translation requires much more large parallel corpora. A Korean-English parallel corpus, however, is not yet enoughly available, little research on this subject is being conducted. In this paper we present a hybrid method of aligning sentences for Korean-English parallel corpora. We use bilingual news wire web pages, reading comprehension materials for English learners, computer-related technical documents and help files of localized software for building a Korean-English parallel corpus. Our hybrid method combines sentence-length based and word-correspondence based methods. We show the results of experimentation and evaluate them. Alignment results from using a full translation model are very encouraging, especially when we apply alignment results to an SMT system: 0.66% for BLEU score and 9.94% for NIST score improvement compared to the previous method.

Mean F0, Jitter, Shimmer, and NHR were measured in 21 opera singers, 13 Korean traditional 'pansori' singers, and 21 non-singers. Four voice sampling conditions were ordinary /α/ prolongation, /α/ prolongation using vocal technique as if the subjects were singing, oral reading of the words of a song, and singing. One-way ANOVA and Sheffe post-hoc analysis were used to identify significant differences among the groups. The mean F0 was significantly different among the 3 groups in all conditions except for the ordinary /α/ prolongation condition. The opera singers produced lower jitter and NHR compared to 'pansori' singers and non-singers only in the singing condition.

The study examines how Koreans' politeness is realized in a speech act, request. The main focus is to explore underlying rationale and influence involved in their performance, not just the comparison of difference in politeness realization between native and nonnative speakers of English, as previous studies did. The study employs the DCT, an attached politeness scale questionnaire, and interviews. Twenty nine university students participated in the study. Interchangeable reading of the three data yields some interesting and valuable insights. The participants heavily rely on a few formulaic expressions to express politeness, such as interrogatives with modal verbs, please and excuse me as a politeness marker. They want to use honorific address terms that is literally translated into English, and have a belief that there are honorific words in English as in Korean. The study refers to the participants' voice on indirectness, nonverbal messages, and expressions with different connotations between English and Korean.

Syntactic ambiguity can be understood by context usually, especially in reading and writing. Because phonological structure including stress, intonation and phonological phenomena can be pronounced differently according to different syntactic structures, syntactic ambiguity can be solved by phonological structure in listening and speaking. The objectives of this study was to survey how Korean English teachers apply phonological structures in order to solve syntactic ambiguity. The results of this study is as follows: First, Korean English leachers applied Compound Stress Rules well, when the second word was not branched. But they did not apply Compound Stress Rules well, when the second word was branched. Second, several Korean English teachers did not apply Nuclear Stress Rules well. They usually put the strongest stress on the first word. Third Korean English teachers did not differentiate appropriate applying situation of palatalization. They applied palatalization at both the single and the separated Phonological Phrase. Fourth, Korean English teachers did not apply stress shifting when stress crash happened. Because they did not apply stress shifting, they put the strongest stress on inappropriate syllable.
