Abstract

Objective: The purpose of this study was to examine the characteristics of prosody of ambiguous sentences in patients with right hemisphere damage(RHD). Methods: Sentences with each word prosodically focused were used to investigate. Several acoustic parameters such as intensity, F0, and duration were measured to identify characteristics of prosody in patients with lesions in the right hemisphere and normal controls. All speech samples were recorded using the Praat 4.3.14 software. Data were analyzed with the independent sample t-test using SPSS 18.0. Results: The results of this study are as follows: First, intensity of the first syllable of the focus word was different between the two groups in several sentences. Second, F0 was different between the two groups in all sentences. Third, duration was different between the groups in several sentences. Accordingly, prosody were varied and values of acoustic parameters differed due to the focus of utterance. The group with right hemisphere damage showed restricted prosody. Conclusions: Intensity, duration, and F0 are all used as elements of prosody in emphasizing structural and pragmatic meaning, but according to the focus, strength and duration were related to F0. In contrast, F0 has a significant linguistic difference, but there was a significant difference between the RHD and normal people, so F0 can be a discriminatory factor of rhyme evaluation of the right hemisphere damaged and it is necessary to accumulate more strong evidence through future research.

목적: 본 연구의 목적은 우반구 손상인에게 대조 초점의 중의성 문장에 대한 운율 특성을 알아보고자 하였다. 연구방법: 본 연구는 본 연구는 초점 운율을 조사하기 위해서 강도, F0, 지속시간 등의 음향학적 매개변수를 검사하였다. 정상인과 우반구 손상인의 모든 구어 샘플은 Praat 4.3.14로 분석하였으며 SPSS 18.0을 사용하여 독립 t-test를 통해 자료를 분석하였다. 결과: 본 연구의 결과는 다음과 같다. 첫째, 첫음절의 강도는 집단 간 유의미한 차이를 나타내었다. 둘째, F0은 모든 집단에서 유의미한 차이를 나타내었다. 셋째, 지속시간은 모든 집단에서 유의미한 차이를 나타내었다. 결론: 강도, 지속시간, F0는 모두 구조적 화용적 의미를 강조하는 데 있어서 운율의 요소로써 사용되지만, 초점에 따라서 강도와 지속시간은 F0와 연관성이 있었다. 그에 비해 F0는 언어학적으로도 유의미한 차이가 있었지만 손상인과 정상인 간에도 유의미한 차이가 있었기 때문에 F0는 우반구 손상인의 운율적 평가의 변별 요인이 될 수 있으며 차후의 연구를 통해 더 강력한 증거를 축적할 필요가 있을 것이다.
