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. > The AURORA project ( 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: ********************************* 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: www: ***********************************************
