This task aims at evaluating source separation and denoising techniques in the context of speech enhancement by merging two datasets: the [http://sisec2010.wiki.irisa.fr/tiki-index.php?page=Source+separation+in+the+presence+of+real-world+background+noise|SiSEC 2010 noisy speech dataset] and the [http://www.dcs.shef.ac.uk/spandh/chime/PCC/datasets.html|CHiME corpus]. Both datasets consist of two-channel mixtures of one speech source and real-world background noise, so that algorithms applicable to one dataset are applicable to the other without additional effort. The source separation results obtained over the latter dataset will be analyzed in line of the speech recognition results obtained over that dataset as part of the [http://www.dcs.shef.ac.uk/spandh/chime/challenge.html|CHiME Challenge].
