- W2595250097 abstract "노인 음성은 연령에 따른 호흡, 발성, 공명 등의 생리적 변화에 의하여 다량의 잡음이 발생된다. 따라서 노인 음성으로 음성인식 및 합성, 분석 소프트웨어등과 같은 융복합 헬스케어 기기를 동작시키고자 할 때, 성능을 저하시키는 결과를 야기한다. 그러므로 노인 음성을 분석하여 그들의 목소리로 다양한 헬스케어 기기를 잘 운영할 수 있는 위한 연구 개발이 필요하다. 따라서 본 연구는 노인 음성 잡음을 고려하여 기존의 대칭 구조 고차 미분 에너지 함수를 이용하여 노인 음성에서의 음성 구간 검출 알고리즘을 연구하였으며, 자기상관함수와 AMDF 방법과 비교하여 노인 음성에서의 음성 구간 검출에 보다 우수한 성능을 가지는 것을 확인하였다. 본 논문에서 제시하는 음성 구간 검출 알고리즘은 노인을 위한 음성 인터페이스에 적용함으로써 노인들의 스마트 기기에의 접근성을 높이고, 더 나아가 노인들을 위한 융복합 웨어러블 디바이스 성능 개선 및 다양한 개발이 가능할 것으로 전망한다. Since the elderly voices include a lot of noise caused by physiological changes in respiration, phonation, and resonance, the performance of the convergence health-care equipments such as speech recognition, synthesis, analysis program done by elderly voice is deteriorated. Therefore it is necessary to develop researches to operate health-care instruments with elderly voices. In this study, a voice activity detection using a symmetric higher-order differential energy function (SHODEO) was developed and was compared with auto-correlation function(ACF) and the average magnitude difference function(AMDF). It was confirmed to have a better performance than other methods in the voice interval detection. The voice activity detection will be applied to a voice interface for the elderly to improve the accessibility of the smart devices." @default.
