Abstract

This paper investigates the potential performance of generalized
subspace filters for speech enhancement in cocktail party
situations with very poor signal/noise ratio, e.g. down to
-15 dB. Performance metrics output signal/noise ratio, signal/
distortion ratio, speech quality rating and speech intelligibility
rating are mapped as functions of two algorithm parameters,
revealing clear trade-off options between noise, distortion
and subjective performances and a recommended choice
of trade-off. Given sufficiently good noise statistics, SNR
improvements around 20 dB as well as PESQ quality and
STOI intelligibility rating improvements exceeding 1.0 and
0.2 points respectively are found. This shows the potential of
the method.
