The two work items within ETSI are :

ETSI DES/STQ WI007 : Distributed Speech Recognition - Front-End Feature Extraction Algorithm & Compression Algorithm ETSI DES/STQ WI008 : Distributed Speech Recognition - Advanced Feature Extraction Algorithm The Aurora project is now entering the operational work of WI008. For this purpose, interested parties are invited to contribute to the standardisation activity. In order to initiate the process, the Aurora project has established an experimental framework to enable DSR front-ends to be evaluated. The framework makes use of a speech database based on TI digits with artificially added noise over a range of SNR’s and Entropic’s HTK (with a particular configuration) as the "standard" HMM recognizer.

Two original copies of the contract (postscript | WinWord 6) must be sent to ELDA. To be valid these contracts must be initialled and signed. The user should annex to the contract the proof that he obtained the right to use the TI digits from LDC (ref. LDC93S10). This may be a signed licence agreement or a proof of membership payment for 1993.

The price for this database is : EUR 250
