변수로서 악센트구 내 음절수, 첫째 음절과 둘째 음절의 음절 유형 (폐음절 대 개음절), 첫째 음절과 둘째 음절의 초성 자음의 유형 등을 고려하여 선택된 3음절 무의미 단어 35개와 4음절 무의미 단어 35개를 사용하여 4음절 이상으로 이루어진 서울말 악센트구의 성조에 대 하여 조사하였다. 이 실험의 발화에서는 1) 악센트구성조에 대하여 4음절과 5음절의 차이는 나타나지 않았다. 2) 음절 유형은 첫째 음절의 초성 자음이 보통음일 때는 유의한 영향을 미치지 않았으나, 센소리일 때는 둘째 음절의 유형이 유의한 영향을 미치는 것으로 드러났다 3) 악센트구 성조에 대하여 첫째 음절의 초성 자음의 유형이 중요한 역할을 하는 것으로 나타났다 첫째 음절의 초성 자음이 센소리일 때 악센트구 4개 성조 모두 보통음일 때에 비해 높게 나타났다. 4) 둘째 음절의 초성 자음의 유형도 자신의 성조에 유의한 영향을 끼치는 것으로 드러났으며 센 소리로 시작하는 경우에 다른 유형의 자음에 비하여 자신의 피치 값이 높은 것으로 나타났다.

The present study was to investigate the speech intelligibility of esophageal speech, which is the way that the laryngectomized people who lost their voices by total laryngectomy can phonate by using the airstream driven into esophagus, not trachea. Three normal listeners transcribed the CVVand VCV syllables produced by 10 esophageal speakers. As a result, overall intelligibility of esophageal speech was 27%. Affricates showed the highest intelligibility, and fricatives, the lowest. In the aspect of the place of articulation, palatals were the most intelligble, and alveolars, the least. Most of the aspirated consonants showed a low intelligibility. The consonants in VCV syllables were more intelligible than the ones in CVV syllables. The low intelligibility of esophageal speakers is due to insufficient airflow intake into esophagus. Therefore, training to increase airflow intake, as well as correct articulation training, will improve their low intelligibility.

The frequency in which noise energy is generated, that is, the point where the preceding vowel ends is the cut-off frequency. Thereupon, this study intends to examine the correlations between, cut-off frequencies, cut-off frequencies changed by the following vowel, and cut-off frequencies and nasalance score, of fricatives and affricates with the subjects of children with the cleft palate and normal children. The subjects of this study are total 12 children residing in Seoul and Gyeonggi area. Six are the children diagnosed to have the cleft palate and whose chronological age are more than six, and another six are the normal children who are also more than six and whose chronological age and sex correspond to those of the former. Each subject was presented with nonsyllable environment and sentence environment(50 environment) of fricatives and affricates. Regarding meaningless syllable environment and sentence environment of fricatives and affricates, children with the cleft palate had lower cut-off frequencies than normal children. As a result of comparative study on correlations between cut-off frequencies and nasalance score of children with the cleft palate and normal children, it doesn't show statistically significant correlations in both meaningless syllable environment and sentence environment of normal children, but it has statistically significant correlations in sentence environment of children with the cleft palate.

The aims of this study was to investigate influences of speech discrimination score(SDS) depending on inter-syllable pause duration in participant with child of cochlear implantation(CI). 12 child of CI-user participated. The word for SDS was used self-made meaningless three-syllable. The pause duration of inter-syllable was adjusted to 250, 500, 1,000 millisecond(ms). Discrimination score of closed-set speech was obtained at most comfortable loudness(MCL). SDS were improved in CI group for 62.08, 63.75, 69.58 %, but there were no significant changes in child of CI group(p = .4635). SDS was improved depending on inter-syllable pause duration in child of CI.

Nasometer를 통해 얻은 비음치(nasalance score)는 객관적일 뿐만 아니라 훈련된 언어임상가가 청지각적으로 판단한 비음도와 상관관계가 높기 때문에, 공명장애 진단의 보조자료로 유용하다. 그러나 비음치는 자극어에 따라 다양한 수치를 보이므로 공명장애의 진단을 위해서는 타당하고 신비로운 자극어의 개발이 요구되고 있다 따라서 본 연구는 비음치에 영향을 미치는 주요한 음운 환경이 무엇인지 살펴보고, 무의미 1음절어와 유의미 문장 자극어 중 어떤 것이 더 신뢰로운지 알아보아, 비음치 측적을 위한 자극어 개발에 기초를 마련하고자 하였다.

The aim of this study is to prepare basic data that can be used for evaluation and intervention by investigating the characteristics of diphthongs produced by children with speech sound disorders. To confirm this, two groups of 10 children each, with and without speech sound disorders were asked to imitate the meaningless two-syllable 'diphthongs + da'. The slope of F1 and F2, amount of change of formant, and duration of glide were analyzed by Praat (version 6.1.16). As a result, the difference between the two groups was found in the slope of F1 of /ju/. Children with speech sound disorders had smaller changes in formants and shorter duration time values compared to normal children, and there were statistically significant differences. The amount of change in formant in the glide was found in F1 of /ju, jɛ/, F2 of /jɑ, jɛ/, and there were significant differences in the duration of glide in /ju, jɛ/. The results of this study showed that the range of articulation of diphthongs in children with speech sound disorders is relatively smaller than that of normal children, thus the time it takes to articulate was reduced. These results suggest that the range of articulation and acoustic analysis should be further investigated for evaluation and intervention regarding diphthongs of children with speech sound disorders.
