The Aurora project was originally set up to establish a worldwide standard for the feature extraction software which forms the core of the front-end of a DSR (Distributed Speech Recognition) system. ETSI formally adopted this activity as work items 007 and 008.

The two work items within ETSI are :
ETSI DES/STQ WI007 : DSR - Front-end feature extraction algorithm & compression algorithm
ETSI DES/STQ WI008 : DSR - Advanced feature extraction algorithm

The Aurora project has released a number of list files for performing the training and testing on the Wall Street Journal (WSJ0) data at two sampling rates -8 kHz and 16 kHz. The Aurora 4b, has been released. It contains noisy versions of the Nov'92 WSJ0 development set.

Two original copies of the contract (pdf | doc | rtf) must be sent to ELDA.
