스펙트럴 서브트렉션과 비동기 KLT 잡음 감소 기법의 조합에 의한 음성 인식 성능 개선
Improvement of the ASR Robustness using Combinations of Spectral Subtraction and KLT-based Adaptive Comb-filtering
초록
In this paper, the combinations of speech enhancement techniques are experimented. Specifically, the spectral subtraction, KLT based comb-filtering, and their combinations are applied to the Aurora2 database. The results show that recognition accuracy is improved when KLT based comb-filtering is applied after spectral subtraction.
