Heading to #Interspeech2025!
I’ll be involved in a tutorial, regular and special sessions (22 papers) & MLC-SLM workshop — and excited to chat about our new project: ESPnet3, CHiME-9, Urgent3, LARC, and YODAS++.
If you’re interested, come say hi — let’s collaborate! 🚀

Join the CHiME8 pitching session on Monday, April 15th, at 17:30 at the HSCMA workshop venue (Room 205 at COEX, ICASSP venue).

The organizers of the three tracks of this year's edition will briefly introduce their tasks and answer questions.

We hope to see you there.

Apparently #SpeechRecognition isn't solved yet! new and important dataset and challenge for distant meeting transcription from @AlonVin and colleagues at @Microsoft and @chimechallenge

[Alon Vinnikov @AlonVin]

You might think speech recognition is "solved" with models such as @OpenAI’s Whisper, but it's not. Natural conversations with distant microphones still lack effective solutions.

To illustrate, on our newly released NOTSOFAR meeting benchmark, Whisper large-v3 with head-mounted mics achieves 9.3% WER (word-error-rate), yet on audio from a distant mic it climbs to 37.4% WER. The culprits are reverberation, noise, and overlapping speech, which interfere with the source signal.

What's the missing ingredient? We believe it's datasets.
The problem is not amenable to web scraping. Benchmarking datasets are scarce given their complex collection process. Microphone arrays, useful for speech separation, are rarely featured in labeled datasets, necessitating simulation to teach neural networks to utilize such arrays.

To bridge the gap our team at @Microsoft has released a benchmarking dataset of 280 recorded meetings, and a 1000-hour simulated training set synthesized for real-world generalization.

Join our challenge "NOTSOFAR: Distant Meeting Transcription with a Single Device", part of CHiME-8, to explore these resources and advance the field.

We are pleased to announce that the leaderboard for the tasks is now available online and can be accessed at: https://t.co/0Vl9vRLb1V.
Additionally, the teams have refined the baselines.

[CHiME Challenge @chimechallenge]

It gives us great pleasure to pre-announce the 8th CHiME Speech Separation and Recognition Challenge (CHiME-8) that will launch in February 2024.

CHiME-8 TASKS includes:
Task 1 - DASR
Task 2 - NOTSOFAR-1
Task 3 - MMCSG

The final results for the CHiME-7 Task 1 (Distant Meeting Transcription with Multiple Devices) are out: https://t.co/vDryIZCd1V
Congratulations and many thanks to all participants 🎉, it was an arduos challenge (baseline was ~ on par with Whisper large in sub-track). (1)

[CHiME Challenge @chimechallenge]

We also had a nice tour at the Meta Dublin office after the workshop :)

[CHiME Challenge @chimechallenge]

The CHiME workshop was finished with great success! Thanks, everyone, for the excellent presentations and discussions! Please remember that the task proposal deadline is September 25th!

[Simon Leglaive @SimonLeglaive]

Listening test results and audio examples are out on the challenge website!

Congratulations to the Northwestern Polytechnical University and ByteDance team for winning, and many thanks to all participants!

We'll soon provide a further analysis of the results.
