Currently development of the Artificial Intelligence technology is rapidly progressing in the era of the Fourth Industrial Revolution. The government is trying to improve the education of Artificial Intelligence and cultivating human resources. However there are very few cases where A.I technology is actually used in public education classes. Therefore we designed a text repository by implementing A.I speech recognition to provide career counseling for elementary school students. In the meantime, there have been many difficulties in giving advance consultations required for students' career counseling. In this study we suggested A.I speech recognition technology which can solve addressed problem and we planned various ways to make the program more educational. To conclude we expect A.I technology implemented in this study provides effective solution to career counseling.

This study examined the deletion of onset consonant in the word-internal structure in spontaneous Seoul Korean speech. It used the dataset of speakers in their 20s extracted from the Korean Corpus of Spontaneous Speech (Yun et al., 2015). The proportion of deletion of word-internal onset consonants was analyzed using the linear mixed-effects regression model. The factors that promoted the deletion of onsets were primarily the types of consonants and their phonetic contexts. The results showed that onset deletion was more likely to occur for a lenis velar stop [k] than the other consonants, and in the phonetic contexts, when the preceding vowel was a low central vowel [a]. Moreover, some speakers tended to more frequently delete onset consonants (e.g., [k] and [n]) than other speakers, which reflected individual differences. This study implies that word-internal onsets undergo a process of gradient reduction within individuals' articulatory strategies.

The purpose of the current study is to investigate the realization of speech rhythm in English as spoken by Korean learners of English. The study particularly aims to examine the rhythm metrics of English read speech by learners who speak Busan or the South Kyungsang dialect of Korean. Twenty-four learners whose L1 is Busan Korean and eight native speakers of English read a passage wherein five sentences were segmented and labeled as vocalic and intervocalic intervals. Various rhythm metrics such as %V, Varcos, and Pairwise Variability Indexes (PVIs) were calculated. The results show that Korean learners read English sentences with significantly more vocalic and consonantal intervals at a slower speech rate than native English speakers. The analyses of rhythm metrics revealed that when the speech rate was not normalized, Korean learners' English showed more variability in the length of consonantal and vocalic intervals. However, speech-rate-normalized rhythm metrics for vocalic intervals indicated that Korean learners transferred their L1 rhythmic structures (a syllable-timed language) into their L2 speech (a stress-timed language). Overall, the results suggest that Korean learners' English reflects the rhythmic characteristics of their L1. The effect of the learners' L1 dialect on the realization of L2 speech rhythm is also speculated.

The purpose of this study was to develop the cognitive behavioral group counseling program to relieve elementary children of speech anxiety and to examine its effects. The program was developed on the basis of the cognitive, affective, and behavioral activities. The cognitive activities were based on the REBT procedures, and affective activities included making child's nickname, finding out his own strengths and exchanging positive feedback each other and behavioral activities included training assertiveness, coaching and practicing speech behavior etc, Subjects were 14 elementary children from M elementary school in Gwangju. They had the highest scores at the speech anxiety test which was administrated to all the sixth graders of M elementary school. Seven subjects were randomly allocated to experimental group and control group respectively. Two speech anxiety tests and one speech behavior checklist were administrated as pre- and post-tests. The collected data was analyzed by ANCOVA. Research results demonstrated that the experimental group showed statistically significant changes in the scores of the speech anxiety test and the speech behavior checklist comparing with the control group. Then it was accepted that the program which was developed in this study could make effects on the reduction of elementary children's speech anxiety.

Purpose: This study investigates Korean speech sound development, including articulatory error patterns, among the Japanese-Korean children whose mothers are Japanese immigrants to Korea. Methods: The subjects were 28 Japanese-Korean children with normal development born to Japanese women immigrants who lived in Jeonbuk province, Korea. They were assessed through Computerized Speech Lab 4500. The control group consisted of 15 Korean children who lived in the same area. Results: The values of the voice onset time of consonants /$p^h$/, /t/, /$t^h$/, and/$k^*$/ among the children were prolonged. The children replaced the lenis sounds with aspirated or fortis sounds rather than replacing the fortis sounds with lenis or aspirated sounds, which are typical among Japanese immigrants. The children showed numerous articulatory errors for /c/ and /I/ sounds (similar to Koreans) rather than errors on /p/ sounds, which are more frequent among Japanese immigrants. The vowel formants of the children showed a significantly prolonged vowel /o/ as compared to that of Korean children ($P$<0.05). The Japanese immigrants and their children showed a similar substitution /n/ for /ɧ/ [Japanese immigrants (62.5%) vs Japanese-Korean children (14.3%)], which is rarely seen among Koreans. Conclusion: The findings suggest that Korean speech sound development among Japanese-Korean children is influenced not only by the Korean language environment but also by their maternal language. Therefore, appropriate language education programs may be warranted not only or immigrant women but also for their children.

The purpose of this study is to examine the status and perceptions, needs of speech language pathologists(SLPs) for the intervention of non-verbal autism spectrum disorders(ASD) through a survey. Among SLPs registered in the Korean Association of Speech-Language Pathologists (KSLP), 116 SLPs participated in this survey. The result is as follows. First, 96.6% of SLP reported that they had been referred for non-verbal ASD, and it was found that SELSI was the most used evaluation tool, and communication ability and social interaction were the most frequently used intervention goals. Second, 86.2% of the SLP said that speech therapy had difficulties, and the reason for the burden was the lack of speech therapy methods. Also, the level of knowledge of speech therapy for non-verbal ASD was low in the treatment area, and the level of confidence responded positively only in communication ability and social interaction. Third, education that was considered necessary within the curriculum was education on treatment methods, and it was found that the improvement points of education other than regular courses were increased education such as expert courses and workshops and activation of supervision. From the results of this study, it is expected that the related curriculum will be expanded and improved in the future.

The speech recognition service is used as an ancillary means of communication by converting and visualizing the speaker's voice into text to the hearing impaired persons. However, in open environments such as classrooms and conference rooms it is difficult to provide speech recognition service to many hearing impaired persons. For this, a method is needed to efficiently provide it according to the surrounding environment. In this paper, we propose a system that recognizes the speaker's voice and transmits the converted text to many hearing impaired persons as messages. The proposed system uses the MQTT protocol to deliver messages to many users at the same time. The end-to-end delay was measured to confirm the service delay of the proposed system according to the QoS level setting of the MQTT protocol. As a result of the measurement, the delay between the most reliable Qos level 2 and 0 is 111ms, confirming that it does not have a great influence on conversation recognition.

The objective of this study is to classify the conversations in Chinese textbooks into four social units (speech community, speech situation, speech event, speech act) adopted by Dell Hymes (1972), and suggest application of the results involving the conversation to the curriculum of Chinese education. Towards this end, this study assumes every conversation in the Chinese textbooks as coordination of specific speech events and acts under specific situations. This study introduces the concept of social unit adopted by Dell Hymes (1972), and elucidates their role in conversation. Thus, this study reconsiders the conversations recorded in the textbooks not from a morphological or syntactic viewpoint but from a speech perspective. Finally, this study suggests effective use of the results in the Chinese conversation classes.

The current study was designed to investigate which type of phrase boundary tones high-intermediate Korean learners of English used in their spontaneous speech. These boundary tones were compared to those used in native speakers' spontaneous speech to examine whether the learners successfully acquired the use of boundary tones. To achieve this purpose, 10 Korean learners of English and four native speakers of English participated in the current study. The participants were asked to summarize the stories of short videos, and the tonal and the phrasing patterns of the obtained spontaneous speech were analyzed using Tone and Break Indices (ToBI) transcription conventions. The results indicated that both the native speakers and the Korean learners frequently marked their intonational phrase boundaries with high boundary tones. However, regarding the prosodic phrase positions within a sentence, Korean learners frequently used steep rising tones (i.e., H-H%) while native speakers used gradual rising tones (i.e., L-H%) for sentence-final intonational phrases. Overall, the findings suggested that high-intermediate Korean learners understood the forward-looking function of the high boundary tones and that they were able to make use of these tones to mark intonational phrases in their spontaneous speech.
