		     *** AURORA Project Database ***

ELRA is releasing two databases made within the ETSI STQ-AURORA DSR
working group.
_______________________________________
AURORA Project Database 2.0
_______________________________________

The Aurora project is releasing a revised version of the Noisy TI digits
database to follow on the work of ETSI. This CD set is a replacement for
the previous set (version 1.0 consisted of 2 CDs while version 2.0 now
consists of 4 CDs) .

This database is intended for the evaluation of algorithms for front-end
feature extraction algorithms in background noise but may also be used
more widely by speech researchers to evaluate and compare the performance
of noise robust speech recognition algorithms.

Compared to version 1.0 the changes are as follows:
1) The files are restored to the energy level of the original speech
in the TI digits database.
2) One of the noise types added to the speech has been changed (the babble
one)
3) There is an additional test sets where the noises are mismatched to
those used in the training set
4) There is a convolutional distortion test.
5) There is a clean training set

The CD ROM will be used for the next round of ETSI Aurora standards
evaluation.

AURORA Project Database 3.0 - Subset of SpeechDat-Car
Finnish database
_______________________________________

This database is a subset of the SpeechDat-Car database in Finnish
language which has been collected as part of the European Union
funded SpeechDat-Car project. It contains isolated and connected
Finnish digits spoken in the following driving conditions inside a car:

1.	0 km/hr with the car engine on
2.	40-60 km/hr with the car windows closed
3.	40-60 km/hr with the car windows open
4.	100-120km/hr with no music in the background
5.	100-120km/hr with music in the background

The database also contains the software needed to run simulations
using the Entropic's HTK, which has been adopted as the "standard"
HMM recogniser for the Aurora standard evaluation.
