Cross-correlation 기반의 Double-talk detection을 적용한 WebRTC AEC 성능 개선

초록

By replacing existing WebRTC AEC algorithm with proposed algorithm including double-talk detection based on cross-correlation and GSAP,an improved WebRTC AEC is implemented in this paper. The results of the proposed algorithm show more accurate double-talk detection, and present good performance in double-talk period than the output of the existing WebRTC AEC. We employ a ERLE for verifying the proposed algorithm.
