• Set of scripts to perform the Aurora-2 experiment with the advanced ETSI front-end
  
  • TAR archive of scripts (contains README file)


• FaNT – Filtering and Noise Adding Tool
  To create the Aurora-2 and the Aurora-4 data, noise signals have been artificially added to the clean TIDigits (downsampled at 8 kHz) respectively to the WSJ (wall street journal) speech data (downsampled at 8 or 16 kHz). The software tool for noise adding and filtering is available as C program:
  
  • GNU zipped version of the C software
  • PDF document describing the usage of the program

• Aurora-5 - Meeting Recorder Digits
  Recorded in hands-free mode at the International Computer Science Institute in Berkeley
