An approach to doubletalk detection based on non-negative matrix factorization
Cahill, Niall M.; Lawlor, Bob
In this paper a novel approach to doubletalk detection (DTD) is presented. This approach uses a modified Non-Negative Matrix Factorization (NMF) technique originally developed for monaural sound source separation to perform DTD. The efficacy of this approach is demonstrated through experiments using real room impulse responses (RIRs). The properties of this algorithm are then discussed with reference to experimental results.
