Submission
The submission of the systems is open until 17th July 2024 AoE and should be done through Google Form. We allow each team to submit up to three systems per latency category (12 systems in total). For the submission, make sure to have the following ready:
- technical description paper
- system hypotheses and evaluated results for development subset
- system hypotheses for evaluation subset
- outputs of word-timestamp test
The requirements and formats of all of the above are further described below.
Technical description paper
For the technical description, follow the instructions for CHiME-8 challenge papers at the workshop page. The papers should be 4 pages long with one additional page for references. Please describe all of your submitted systems, their latency and the results on development subset. Please submit your abstract before your results and note the CMT paper ID assigned to your abstract as you will need to include it in your Google form submission.
System hypotheses and evaluated results for development subset
Participants should submit a zip file containing the hypotheses files, WER results and latency results, for each submitted system. The zip file should contain the following directory structure:
├── name_of_system_1
│ ├── hypotheses
│ ├── wer
│ └── latency
...
└── name_of_system_N
├── hypotheses
├── wer
└── latency
- Feel free to choose any naming of the systems, but please make sure that they are consistent between all submitted archives.
-
hypotheses
is a directory containing one text file per recording in development subset (169 files in total). It corresponds to the directory accepted by the evaluation script, as described at the challenge Github. The names of the files correspond to the names of the recordings, e.g.1033566334616594_0001_3375_21050
. Each file contains one row per word of the following format:<start-of-word-in-seconds>\t<end-of-word-in-seconds>\t<word>\t<speaker-label>
Note that
<start-of-word-in-seconds>
is not used in any way and you can fill it with any placeholder, such as-
(it is present only to keep the format consistent with references). The field<end-of-word-in-seconds>
corresponds to the word-timestamps that are used to compute latency. For more information about the word-timestamps, please refer to the Evaluation rules.<speaker-label>
is 0 or 1, 0 for SELF (the wearer of the glasses), 1 for OTHER (the conversational partner). -
wer
is a file provided by the evaluation script. Example contents of the file is the following:wer_self;wer_other;nref_self;nref_other;ins_self;ins_other;del_self;del_other;sub_self;sub_other;sa_self;sa_other 0.179;0.244;45247;45518;0.017;0.026;0.042;0.073;0.105;0.123;0.016;0.022
-
latency
is a file provided by the evaluation script. Example contents of the file is the following:mean;std;median 0.145;0.368;0.166
System hypotheses for evaluation subset
For evaluation subset, participants submit only the decoded hypotheses, which we will subsequently evaluate using the evaluation script. The zip file for the evaluation subset thus should contain the following structure:
├── name_of_system_1
│ └── hypotheses
...
└── name_of_system_N
└── hypotheses
- The naming of the systems should be consistent with the one used for development subset.
- The
hypotheses
directory should contain one text file per recording in evaluation subset (189 files in total). The format of the files is the same as for development set (described above).
Outputs of word-timestamp test
For testing the correctness of the provided word-timestamps, the participants are asked to run a timestamp-test as described at the challenge Github. Specifically, you should generate perturbed data by running:
python -m scripts.prepare_perturbed_data
This will create a directory data/perturbation_test
with perturbed and unperturbed version of 20 recordings from development set. For example, for audio modality the perturbed versions are in data/perturbation_test/audio/perturbed
and unperturbed versions are in data/perturbation_test/audio/unperturbed
. You should run your system on both of these versions and submit the created hypotheses. We will confirm the correctness of the timestamps in these hypotheses using the provided scripts/test_timestamps.py
script as described at the challenge Github.
The submitted zip file should have the following structure:
├── name_of_system_1
│ ├── hypotheses_perturbed
│ └── hypotheses_unperturbed
...
└── name_of_system_N
├── hypotheses_perturbed
└── hypotheses_unperturbed
- The naming of the systems should be consistent with the one used for development subset.
- The
hypotheses_perturbed
andhypotheses_unperturbed
directories should contain one text file per recording used in the perturbation test (20 recordings in total). The format of the files is the same as for development set (described above).
If you are unsure about how to provide any of the above files, please contact us at the Slack channel #chime-8-mmcsg or at kzmolikova@meta.com.
