Query: Joint Sound Source Separation and Speaker Recognition   Non-negative Matrix Factorization (NMF) has already been applied to learn
speaker characterizations from single or non-simultaneous speech for speaker
recognition applications. It is also known for its good performance in (blind)
source separation for simultaneous speech. This paper explains how NMF can be
used to jointly solve the two problems in a multichannel speaker recognizer for
simultaneous speech. It is shown how state-of-the-art multichannel NMF for
blind source separation can be easily extended to incorporate speaker
recognition. Experiments on the CHiME corpus show that this method outperforms
the sequential approach of first applying source separation, followed by
speaker recognition that uses state-of-the-art i-vector techniques.
