The AURORA project (http://www.icp.inpg.fr/ELRA/aurora.html) is a focus for
robust ASR work at the moment. The material is digit strings from the TIDIGITS
database + various added noises at different levels.

Soon to be released is SpeechDat-Car, digit strings recorded in cars - will be
available through the ELRA site above.

On a smaller scale, you can get the 100 sound mixtures used in Martin Cooke and
Guy Brown's Ph.D.s from Martin's web site: http://www.dcs.shef.ac.uk/~martin/
