아동이 산출하는 말소리를 평가할 때 단어와 문장을 유도하여 산출한 말소리를 분석하고, 자발화를 이용하여 분석하기도 한다. 단어 검사와 자발화 검사의 한계를 보완할 수 있는 평가 방법으로 문장 따라말하기 과제가 있다. 문장 따라말하기 과제를 통한 아동의 말소리 평가는 자발화와 유사한 특성을 보이면서 단어와 같이 제한된 시간 안에 다양한 음소를 평가할 수 있다. 본 연구에서는 다양한 모음문맥에서 자음을 배치하고 모든 음소가 3회 이상의 출현 기회를 가질 수 있도록 계획된 11개의 문장 따라말하기를 통해 연령과 성별에 따라서 단어단위 음운지표와 개정자음정확도의 발달을 살펴보았다. 전국에 거주하는 3세부터 7세까지 아동 535명을 대상으로 UTAP2에 새롭게 포함된 11개 문장 따라말하기 과제를 실시하였다. 말소리발달을 평가할 수 있는 지표 PCC-R, PWC, PMLU, PWP을 구하였다. 아동은 연령별 6개월 단위로 10개의 집단을 구분하고 각 지표에 대해 연령집단과 성별에 따른 차이를 분석하였다. 연구 결과, 모든 지표에서 연령이 증가함에 따라 수치가 상승하였으며 연령집단 간 차이는 유의하였다. 성별에 따른 차이와 연령과 성별의 상호작용효과는 유의하지 않은 것으로 나타났다. 본 연구는 전국에서 자료를 수집하였고, 연령집단을 6개월로 나누어 보았으며, 집단별 데이터를 충분히 수집하였다는 점과 단어와 자발화 검사의 한계점을 보완할 수 있는 문장 따라말하기라는 새로운 말소리 평가 방법의 연령별 준거 자료를 제시하였다는 측면에서 의의가 있다.

Denasalization that nasals are replaced by stops is an unusual error pattern related to manner of articulation. The purpose of this study is to investigate the prevalence of denasalization and to scrutinize the nasal production according to phonological context for typically developing children and children with speech sound disorders(SSD). 220 typically developing children and 48 SSD children from 2~6 years of age were tested with a formal word test, and those who demonstrate denasalization were selected. In addition, the nasal production of SSD children with denasalization were analyzed for the correctness and the error types using the formal word test and spontaneous conversation. The results were as follows: (1) Denasalization was shown in below 10% of 2-3 years of age with typically developing children and in above 20% of 2-5 years of age with SSD. (2) The SSD children who demonstrate denasalization were categorized into 4 types according to the error context of nasals; nasal errors with all word positions, nasal errors with word-final and word-medial positions, nasal errors with word-medial position preceding vowels, and nasal errors with word-medial position preceding obstruents. These results indicate that denasalization is a clinically important error pattern, and word-medial position preceding obstruents is an essential context for denasalization in terms of Korean phonotactics.

This study was aim to compare the phonological error patterns and PCC(Percentage of Correct Consonants) derived from the single word and spontaneous speech contexts of the speech sound disorders with unknown origin(SSD). The present study suggest that the development phonological error patterns and non-developmental error patterns of the target children, in according to speech context. The subjects were 15 children with SSD up to the age of 5 from 3 years of age. This research use 37 words of APAC(Assessment of Phonology & Articulation for Children) in the single word context and 100 eojeol in the spontaneous speech context. There was no difference of PCC between the single word and the spontaneous speech contexts. Significantly different developmental phonological error patterns between the single word and the spontaneous speech contexts were syllable deletion, word-medial onset deletion, liquid deletion, gliding, affrication, fricative other error, tensing, regressive assimilation. Significantly different non-developmental phonological error patterns were backing, addtion of phoneme, aspirating. The study showed that there was no difference of PCC between elicited single word and spontaneous conversational context. And there were some different phonological error patterns derived from the two contexts of the speech sound disorders. The more important interventions target is the error patterns of the spontaneous speech contexts for the immediate generalization and rising overall intelligibility.

최근 인공지능의 발달로 인해 AI스피커에 대한 연구가 활발히 이루어지고 있다. 조음장애는 구강 안에서 말소리를 제대로 만들지 못해서 제대로 된 언어를 구사하지 못하는 장애를 말한다. 조음장애인들이 AI스피커를 사용하면 발음을 제대로 인식하지 못하기 때문에 사용의 어려움이 있다. 본 논문에서는 경증 조음장애인들이 AI스피커를 이용할 수 있도록 머신러닝 기반 언어교정기의 개발내용에 관하여 기술한다. 이는 언어로 명령 줄 수 있는 여러 시스템에 활용될 수 있을 것으로 기대한다.

The present study aimed to determine the phonological errors of children in Korean-Vietnamese speaking multicultural families through comparison analyses with those of Korean monolingual peers with phonological disorders. The subjects were 38 children aged about 4-6 years. To examine phonological errors, the Urimal Test of Articulation and Phonation (words) was used. Performances were analyzed by frequency. The results showed some differences between the two groups. There was a tendency for children in Korean-Vietnamese speaking multicultural families to show a higher frequency of phonological errors than Korean monolingual children with phonological disorders. However, the former showed lower error percentages in a few error patterns than the latter such as syllable final consonant deletion, showing similar patterns to those of the normal children. They also showed very unique error patterns such as the highest error percentage in palatal affricates. It remains to be seen if these error patterns are just delay in acquisition or phonological disorders.

이 논문은 일본의 호리따씨가 1983년 8월 고베시에서 열린 제4차 세계음성학자 대회에서 발표한 내용의 영역본이다. "음성언어의 직감적 개발"이란 부제가 붙은 "위이훠 방법"이란 호리따씨가 개발해 낸 농아와 그 밖의 언어장애자의 발음 훈련 및 교정법인데, 혀의 감각이 둔한 장애자의 혀에 종이같이 얇은 고자 조각을 붙여서 발음하게 함으로써 정확한 조음 위치를 파악하여 올바른 발음을 익히도록 하는 방법이다. 대회에서도 상당한 관심을 끈 논문이므로 우리나라의 언어치료계를 위하여 소개한다. 이 방법은 음성훈련 및 외국어의 발음교육에도 이용될 수 있을 듯 하다.

The speech intelligibility of congenitally deafened children shows the change after cochlear implantation. The predicting factors of change in speech intelligibility are the age of implantation, the duration of implant use, and communication mode etc.. Among these factors, the age of implantation seems to be one of the most important predictors. But those factors including age of implantation can explain only some parts of the variance. Therefore, the further study to find the factors which affect the speech intelligibility should be done.

The intelligibility of a spoken message is influenced by a number of factors. Intelligibility is a joint product of a speaker and a listener. In addition, intelligibility varies with the nature of the language context and the context of communication. Thus a single intelligibility score can not be ascribed to a given individual apart from listener and listening situation. But there is a clinical and research need to develop assessment measures of intelligibility that are quantitative and analytic. Before developing the index of intelligibility, the crucial factors need to be examined. Among them, the most significant in intelligibility is the speech factors of speakers. The following section reviews the literature dealing with the contribution of segmental and suprasegmental factors in speech intelligibility regarding the hearing impaired, alaryngeal, and motor disorders.

The purpose of this study is to evaluate the prevalence of voice disorders and the Korean voice handicap index in the elderly. For this study, 169 elderly performed two types of questionnaires and vowel /a/ prolongation. Self-reported voice symptoms and the Korean voice handicap index were analyzed and acoustic voice evaluation was performed by MDVP. The results showed that the prevalence of voice disorders in the elderly are significantly higher than that of adults in self-reports. In acoustic evaluation, 32.2% of the male elderly and 40.9% of the female elderly exceeded the thresholds of Jitter (%), Shimmer (%) and NHR. In addition, Korean voice handicap index scores of the female elderly are significantly higher than those of female adults. These findings indicate the high frequency of voice disorders in the elderly and the need to focus on this group. Additional studies on the voice related quality of life for the elderly are needed.

The purpose of this study is to show the aerodynamic characteristics and differences in muscle tension dysphonia and adductor spasmodic dysphonia to predict factors which will provide additional information while preparing for the objective examination standard to distinguish the two dysphonias. Forty-eight individuals diagnosed with muscle tension dysphonia and adductor spasmodic dysphonia participated in this study. PAS was used in order to find the aerodynamic characteristics for the two dysphonias. The outcomes of this study show that the airflow variation and glottal resistance of the two groups showed noticeable differences. This study concludes that the aerodynamic characteristics may be used as additional information on diverse evaluations to classify muscle tension dysphonia and adductor spasmodic dysphonia.
