Expectation-maximisation for speech source separation using convolutive transfer function

Expectation-maximisation for speech source separation using convolutive transfer function

This study addresses the problem of under-determined speech source separation from multichannel microphone signals, i.e. the convolutive mixtures of multiple sources. The time-domain signals are first transformed to the short-time Fourier transform (STFT) domain. To represent the room filters in the...
