Examples of Speech Enhancement using Polynomial Eigenvalue Decomposition (PEVD)
These listening examples are supplementary materials for .
The clean speech and noise signals are taken from the TIMIT corpus  and Noisex  database respectively. The algorithms used in the comparison include
- log-MMSE ,
- the multi-channel Wiener filter (MWF)  in  which uses the Relative Transfer Function (RTF) estimator in  and the noise estimator in ,
- Oracle-MWF (O-MWF) that uses the clean speech signal (ground truth)  and
- PEVD which uses the Sequential Matrix Diagonalisation algorithm .
