Demonstration of the results obtained for the
PASCAL 'CHiME' Challenge
(Speech enhancement in highly non-stationary, multisource noisy environment)
Here we have sound demonstration of speech enhancement in
multisource noisy environment. The original noisy data are available
CHiME Challenge homepage.
and the speech enhancement was done at NTT Communication
The related references can be found at the bottom of this page.
The sound volumes of the demo sounds are normalized by their
maximum absolute value.
To proceed you need the Quicktime pluggin.
The pages have been tested with Firefox 8.0 and Internet Explorer 6.0
