Open-resource setting. The organizers will provide the evaluation inputs and task
formats, but not an official training set. Participants may use publicly available datasets, pretrained
models, and other resources that are legally permitted for academic research.
External resources and disclosure. All external datasets, pretrained models, synthetic
data, data augmentation methods, external tools, and APIs used in a submission must be clearly disclosed
in the system description paper. Participants are responsible for complying with the licenses and terms
of use of all external resources.
Evaluation data and hidden labels. Participants may download and use the officially
released evaluation inputs. The corresponding reference labels and evaluation answers will remain hidden.
Participants must not obtain or use any hidden test annotations, reference outputs, or other undisclosed
evaluation information through data leakage, unauthorized access, or other improper means.
No manual test-set intervention. All submitted predictions and generated waveforms
must be produced automatically by the submitted system. Manual, sample-by-sample annotation, correction,
selection, or modification of test predictions or evaluation outputs is prohibited.
Track 2 generation requirements. Each submitted waveform must be fully generated by
the submitted system from the provided test input. Manual waveform editing, manually selected
sample-level splicing, or test-instance-specific recording is prohibited. Automatic post-processing that
is part of the submitted pipeline is allowed but must be disclosed.
Reproducibility verification. Teams provisionally ranked among the top submissions may
be required to provide inference scripts, model configurations, and environment specifications for
verification. Teams that fail to provide the requested materials within the specified deadline may be
removed from the official final ranking.
System description paper. A system description paper must be submitted by the stated
deadline for a team to be eligible for the official final ranking, awards, and presentation in the
challenge session. Teams without a submitted paper may appear on the public leaderboard but will be
treated as unofficial.
