Dual Channel Based Speech Enhancement Using Novelty Filter for Robust Speech Recognition in Automobile Environments
Jia Hao Beh, R.H. Baran, Hanseok Ko · 2006
A simple and effective dual channel speech enhancement algorithm is presented for robust speech recognition in automobile environments. The proposed algorithm incorporates a novelty filter scheme which functions as an associative memory, whose purpose is to improve the performance of the generalized sidelobe canceller (GSC)
