Experimental study of generalized subspace filters for the cocktail party situation

ICASSP 2016accepted

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 intel…

Kalman filter for speech enhancement in cocktail party scenarios using a codebook-based approach

ICASSP 2016accepted

Enhancement of speech in non-stationary background noise is a challenging task, and conventional single channel speech enhancement algorithms have not been able to improve the speech intelligibility in such scenarios. The work proposed in this paper investigates a single channel Kalman filter based…

Single channel speech enhancement in the modulation domain: New insights in the modulation channel selection framework

ICASSP 2015accepted

Recently, the ideal binary mask has been introduced in the modulation domain by extending the ideal channel selection method to modulation channel selection [1]. This new method shows substantial improvement in speech intelligibility but less than its predecessor despite the higher complexity. Here,…
