This study was aimed to evaluate effect of parents-centered speech intervention program on overall speech and language performances of children with cochlear implant. Ten pairs of mother and child were selected and assigned into two groups: intervention group(G1) and control group(G2). G1 included 5 children with cochlear implant and their mothers who joined the parents-centered program. G2 consisted of 5 children with cochlear implant and their mothers did not participate in the program. To evaluate their speech and language abilities, examination instruments(Preschool Language Scale, and Language Comprehension and Cognition Test) were analyzed. Performances of pre- and post-treatment were analysed by ANOVA procedure. The results were as follows: There were significant differences of speech and language performances between pre- and post-treatment in G1. But there were no significant differences in G2(therapists centered program). G1 showed better performances in language comprehension than G2. This study revealed that parents centered language intervention program would be effective for speech and language development for children with cochlear implant.

The purpose of this study was to find an effect of Metaphon Intervention on the improvement of speech intelligibility of preschool children with articulation-phonological disorders. Subjects were 4 preschool children with articulation-phonological disorders. A multiple baseline design across subjects was used to examine the effect of the program. The program consisted of 2 steps. The first step was composed of concept level, sound level, phoneme level, and word level. The second step was on sentence level. Results were as follows: First, metaphon ability of all subjects was improved after the Metaphon Intervention. Second, speech intelligibility of all subjects was improved after Metaphon Intervention. From the results above, Metaphon Intervention can be effective to improve not only phonological awareness and metaphon but also overall speech intelligibility of preschool children with articulation-phonological disorders.

The number of North Korean refugees entering South Korea is continuously increasing. North Korean speakers show significant differences in vowel and consonant phonetics, length of vowels, and the rhythm and intonation of sentences. The object of this research was to examine the effectiveness of a speech intervention program for North Korean refugees using visual feedback through acoustical analysis for intonation. The subjects were three adults with no speech disabilities who had been in South Korea for less than five years. They had not received any prior treatment for inflection change. The program was set in a discourse situation and used Praat to evaluate intonation and provide visual feedback as demonstrating proper intonation changes through pitch contour. The results after intervention are as follows. First, intonation was significantly improved according to a 5-point subjective evaluation scale. Second, the pitch contour was similar to the contour of standard South Korean pronunciation. The subjects were very satisfied with this initial treatment and showed a high level of motivation. In subsequent study, the development of intervention and the comparison of interventions will be needed as well.

본 연구는 부모의 게슈탈트적 언어중재를 통한 유창성장애인의 유창성 개선에 미치는 영향을 알아보기 위해 실시하였다. 부모의 게슈탈트적 언어중재 과정은 유창성장애인의 말더듬 행동에 대한 이해, 자각, 변화, 적응 그리고 유지단계로 실시하였다. 연구 대상은 신경학적 손상이나 다른 언어 및 발달 장애가 없는 유창성장애인 6명(여성 2명, 남성 4명)으로 하였다. 연구의 결과는 다음과 같다. 부모의 게슈탈트적 언어중재 후 유창성장애인의 말더듬 빈도는 감소하였다. 대상자 모두 비정상적인 유창성 중 단어부분 반복이 치료 전에는 가장 많이 빈도를 나타내었으나 치료 후에는 가장 적은 빈도를 나타내어 개선을 보였다. 그러므로 부모의 게슈탈트적 언어중재는 유창성장애인의 말더듬 빈도를 감소시키며 행동을 긍정적 방향으로 개선시키데 효과가 있었다.

The purpose of the present study was to investigate the effectiveness of self-monitoring on spontaneously initiating speech behavior of the hearing-impaired preschoolers. Three hearing-impaired preschoolers were selected from a special school for the deaf. They showed some vocalizations and words under intensive instruction settings, but never spontaneously spoke as a means of communication. Multiple probe design was applied in this study. During the self-monitoring intervention, each child was trained to assess whether his own initiating speech behavior was occurred or not, and then record his own behavior's occurrence on the self-recording sheets and self-graphing sheets. The vibration of handphone was used as a tactile cue for self-monitoring. The results of the present study were as follows: (1) self-monitoring significantly increased the percentage of occurrence of spontaneously initiating speech behaviors. (2) Increased level of spontaneously initiating speech behavior were generalized into another natural instruction (cognitive) settings. (3) Increased level of spontaneously initiating speech behavior were maintained after four weeks from the termination of the intervention.

본 연구에서는 단일대상연구로서 speech cues를 이용한 반복훈련이 뇌성마비 아동의 자음정확도 및 말명료도에 미치는 영향에 대해 알아보고자 하였다. 연구에는 만 5-8세의 뇌성마비 아동 3명이 참여하였다. 중재는 한 달간 주 4회, 총 16회기 동안 진행하였으며, 한 회기는 30분으로 구성하였다. 훈련과제는 목표 음소가 포함된 1-2음절의 단어와 2어절의 문장을 speech cues의 두 가지 발화유형인 'Big mouth'와 'Strong voice'로 훈련하였다. 연구 결과, 첫째, 세 아동 모두 자음정확도와 말명료도의 평균이 중재단계에서 증가하였으나, 효과크기는 아동 간 상이하였다. 또한, 자음정확도에 비해 말명료도에서 더 높은 효과가 나타났다. 세 아동 모두 훈련 문항에서 유지 효과도 나타났다. 둘째, 세 아동 모두 비훈련 단어와 문장에서 일반화 효과가 나타났다. 따라서 speech cues를 이용한 반복훈련을 통해 뇌성마비 아동의 자음정확도와 말명료도가 증가된 것을 알 수 있었으며, 임상에서 좀 더 쉽고 간편한 중재로 그 효용성이 있다는 것을 확인하였다.

The purpose of this study was to investigate the effect of articulatory intervention using visual phonics to improve the speech intelligibility of children with impaired hearing. The subjects of the study were five hearing impaired children. As per the results of the UTAP articulation tests, five phonemes with the most frequent errors were selected for each child and a total of 10 sessions were provided. The methodology involved analyzing vowel space and related measures (vowel space area, vowel articulatory index, formant centralization ratio, and F2i/F2u ratio) before and after the visual phonics intervention. After the articulation intervention, every child's speech intelligibility improved, their vowel space area was widened, the FCR value decreased, and the F2ratio value increased. These results show that the use of visual phonics through symbolic images and hand clues has a positive effect in terms of improving the speech intelligibility of children with impaired hearing.

Background and Objectives: Music listening has a concomitant effect on structural and functional organization of the brain. It helps in relaxation, mind training and neural strengthening. In relation to it, the present study was aimed to find the effect of Carnatic music listening training (MLT) on speech in noise performance in adults. Subjects and Methods: A total of 28 participants (40-70 years) were recruited in the study. Based on randomized control trial, they were divided into intervention and control group. Intervention group underwent a short-term MLT. Quick Speech-in-Noise in Kannada was used as an outcome measure. Results: Results were analysed using mixed method analysis of variance (ANOVA) and repeated measures ANOVA. There was a significant difference between intervention and control group post MLT. The results of the second continuum revealed no statistically significant difference between post training and follow-up scores in both the groups. Conclusions: In conclusion short-term MLT resulted in betterment of speech in noise performance. MLT can be hence used as a viable tool in formal auditory training for better prognosis.

본 연구는 국외에서 개발된 비단어 중재접근법을 수정 및 보완하여 한국어 비단어 중재접근법을 확립하고, 아동기 말실행증 아동에게 직접 적용하여 그 효과를 확인하기 위해 실시되었다. 궁극적인 목적은 비단어를 이용한 중재가 아동기 말실행증의 말운동프로그래밍 능력을 개선시켜 비단어 산출 및 단어로의 일반화에 효과적인지 알아보기 위함에 있다. 중재는 아동기 말실행증의 진단 특성을 보이는 5세 6개월의 남아를 대상으로, ABA설계를 사용한 단일대상연구를 실시하였다. 중재에 사용된 비단어는 아동 맞춤형으로 제작하였으며, 한 회기당 60분씩 주 2회로, 총 12회기를 실시하였다. 그 결과 중재한 3음절 비단어의 모든 지표가 향상되었으며, 중재하지 않은 3음절, 4음절 비단어 및 단어로의 일반화를 확인하였다. 단, 단어로의 일반화 효과는 비단어로의 일반화 효과에 비해 미비하였다. 비단어 중재는 대상 아동의 말운동프로그래밍 능력을 개선시키는데 효과적이었다. 그 결과 운동프로그래밍 손상에 기인한 전환 오류가 크게 감소하였고, 중재하지 않은 비단어의 산출 능력이 큰 폭으로 증가하였다. 그러나 강력하게 습관화된 단어 오류를 완전히 개선시키는 데에는 한계가 있었으며, 이는 보다 집중적이고 반복적인 중재 일정을 제공했을 때 기대할 수 있는 결과일 것이다.
