Dear Auditory List

We are working on several new algorithms to enable us to extract speech signals in noisy environments, and are seeking ways to objectively validate the capabilities of our algorithms.  Does anyone on the list know of a set of well characterized speech and noise files that are available for downloading and that may have been used by others in evaluations of noise reduction strategies?  Examples of conditions that we would be interested in include:  speakers and stationary noise, various types of non-stationary noise, two overlapping speakers, speech and music, car environments, strongly echoic environments, etc.

Thank you in advance.
