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/ ********************************* Professor Phil Green Speech and Hearing Research Group Department of Computer Science University of Sheffield Regent Court 211 Portobello St., Sheffield S1 4DP UK phone: (44) 114 22 21828 fax: (44) 114 22 21810 email: p.green(at)dcs.shef.ac.uk www: http://www.dcs.shef.ac.uk/people/P.Green/ ***********************************************
