ICASSP 2023 Speech Signal Improvement Challenge
The ICASSP 2023 Speech Signal Improvement Challenge is intended to stimulate
research in the area of improving the speech signal quality in communication
systems. The speech signal quality can be measured with SIG in ITU-T P.835 and
is still a top issue in audio communication and conferencing systems. For
example, in the ICASSP 2022 Deep Noise Suppression challenge, the improvement
in the background and overall quality is impressive, but the improvement in the
speech signal is statistically zero. To improve the speech signal the following
speech impairment areas must be addressed: coloration, discontinuity, loudness,
and reverberation. A dataset and test set were provided for the challenge, and
the winners were determined using an extended crowdsourced implementation of
ITU-T P.80's listening phase . The results show significant improvement was
made across all measured dimensions of speech quality
