Introduction to the Blind Source (Speech) Separation Corpus

The Blind Source Separation (BSS) corpus is a collection of digital recordings of mixtures of speech signals and background noise in various acoustic environments. These real-world recordings can be used to evaluate various BSS and other speech enhancement algorithms using a standard test set. In addition, impulse responses for various acoustic environments are available for use in controlled simulation of different “mixing environments.”

The recordings were made under a grant from the Air Force Research Laboratories and are freely available for download.
