Cepstrum-based deconvolution for speech dereverberation
Shankar Subramaniam, Athina P. Petropulu, C. Wendt · IEEE Transactions on Speech and Audio Processing · 1996
We present a blind deconvolution-based approach for the restoration of speech degraded by the acoustic environment. The proposed scheme processes the outputs of two microphones using cepstra operations and the theory of signal reconstruction from phase only. Under mild assumptions, it reconstructs the room impulse response associated with each microphone and restores the speech signal.
