Submission

The submission system is open until 6 Feb 2026. Systems should be sumbitted using this Google Form. We allow each team to submit up to three systems for the challenge. For the submission, make sure to have the following ready:

A technical description paper submitted to the HSCMA & CHiME Workshop.
System outputs for the development and evaluation subset.

Technical description paper

For the technical description, please follow the CHiME-9 challenge paper guidelines provided on the HSCMA&CHiME workshop website. Papers should be up to 4 pages in length, with up to one additional page for references.

Your paper should describe all submitted systems and report objective results on the development subset.

Please submit your paper before completing the Google Form. You will receive an OpenReview Paper ID upon submission; this ID must be entered in the Google Form as part of your submission.

System outputs

The evaluation involves two types of wearable devices:

Aria smart glasses
Hearing Aid (HA) devices

Each device will be evaluated separately, but we encourage participants to prepare signals for both devices.

Required Output

For each device and each session, you must submit three audio signals corresponding to the people the device-wearer is conversing with.

You can identify the relevant speakers using the metadata files:

📄 metadata/sessions.dev.csv
📄 metadata/sessions.eval.csv

This CSV file provides:

The session ID
The positions of the Aria and HA device wearers
The participant IDs (Pxxx) in each position

Example `sessions.dev.csv`

session,aria_pos,ha_pos,pos1,pos2,pos3,pos14
dev_02,3,4,P094,P093,P091,P092
dev_03,2,1,P097,P096,P095,P098
dev_04,3,1,P118,P115,P116,P117
dev_05,1,2,P124,P123,P125,P126
dev_06,4,3,P134,P131,P132,P133
dev_07,1,3,P149,P147,P148,P150
dev_09,2,4,P160,P161,P159,P162
dev_10,3,4,P179,P181,P182,P180
dev_11,2,1,P186,P184,P183,P185
dev_12,1,2,P187,P188,P189,P190

For example, in session dev_02:

The Aria wearer is in position 3 (P091) and is speaking with P092, P093, and P094
The HA wearer is in position 4 (P092) and is speaking with P091, P093, and P094

File Naming Format

Use the following format for each audio signal:

<session_ID>.<device>.<participant_ID>.wav

For example, for session dev_02, you need to prepare the following signals.

Aria signals:

dev_02.aria.P092.wav
dev_02.aria.P093.wav
dev_02.aria.P094.wav

HA signals:

dev_02.ha.P091.wav
dev_02.ha.P093.wav
dev_02.ha.P094.wav

Additional Requirements

🎧 Sampling Rate: 16 kHz
⏱️ Duration: Full session length (36.5 minutes per session)
📂 File Organization: All signals should be placed in the same directory
📊 Total Files:
- Dev Set: 12 sessions → 36 signals per device
- Eval Set: 8 sessions → 24 signals per device

We estimate that for both devices, the total size of the packed directory should be about 3.5 GB. The submission form will allow participants to provide a link from where organizers can download the packed directory.
