The ICASSP 2024 Speech Signal Improvement Grand Challenge is intended to
stimulate research in the area of improving the speech signal quality in
communication systems. This marks our second challenge, building upon the
success from the previous ICASSP 2023 Grand Challenge. We enhance the
competition by introducing a dataset synthesizer, enabling all participating
teams to start at a higher baseline, an objective metric for our extended P.804
tests, transcripts for the 2023 test set, and we add Word Accuracy (WAcc) as a
metric. We evaluate a total of 13 systems in the real-time track and 11 systems
in the non-real-time track using both subjective P.804 and objective Word
Accuracy metrics.
