Abstract

Network Quotient, an important figure in modern society, the intelligibility of speech as a conversation partner to maximize pulling up feeling of liking it as much as possible has become an important issue. The humidity of air in the intelligibility of speech have many influences. Therefore, in this paper, we carried out experiment to apply voice signal analysis techniques which to analyze influenced vocal cords in 30%, 50% and 80%, maintaining a constant humidity of the environment. With this in mind, we carried out experiments on intensity and pitch of voice signal on twenty male 20s in maintaining a constant humidity 30%, 50% and 80% of humidity. Finally, we carried out study to draw a significance through statistical analysis measuring characteristic parameter of vocal cord function to change of humidity.

네트워크 지수가 중요한 현대 사회에서 음성을 통한 전달력 극대화로 대화 상대자로 하여금 호감도를 최대한 끌어 올리는 것이 중요한 사안이 되었다. 이때 공기 중에 포함된 습도는 음성의 전달력에 많은 영향을 미친다. 따라서 본 논문에서는 30%, 50%, 80%의 습도를 일정하게 유지한 환경에서 성대에 미치는 영향을 분석하기 위한 음성신호 분석 기술을 적용한 실험을 수행하여 습도가 음성의 전달력에 미치는 영향을 정량적으로 규명해 보고자 한다. 이를 위해 20대 남성 20명을 대상으로 30%, 50%, 80% 습도 환경을 유지하고 있는 공간에서 1시간동안 노출된 상태에서 음성을 수집하고 성대 진동 변화 및 음성 에너지 크기를 측정한 실험을 수행하였다. 최종적으로 습도 변화에 따른 성대 기능의 특징 요소를 측정하고 통계 분석을 통해 추출된 실험 결과가 통계적 유의성을 갖는지에 대해 분석해 보고자 한다.
