Subspace Methods for Multimicrophone Speech Dereverberation

  title={Subspace Methods for Multimicrophone Speech Dereverberation},
  author={Sharon Gannot and Marc Moonen},
  journal={EURASIP J. Adv. Sig. Proc.},
A novel approach for multimicrophone speech dereverberation is presented. The method is based on the construction of the null subspace of the data matrix in the presence of colored noise, using the generalized singular-value decomposition (GSVD) technique, or the generalized eigenvalue decomposition (GEVD) of the respective correlation matrices. The special Silvester structure of the filtering matrix, related to this subspace, is exploited for deriving a total least squares (TLS) estimate for… CONTINUE READING
