Neural dual extended Kalman filtering: applications in speech enhancement and monaural blind signal separation
Eric A. Wan, A. Nelson · 2002
The removal of noise from speech signals has applications ranging from speech enhancement for cellular communications, to front ends for speech recognition systems. A nonlinear time-domain method called dual extended Kalman filtering (DEKF) is presented for removing nonstationary and colored noise from speech. We further generalize the algorithm to perform the blind separation of two speech signals from a single recording.
