Coming 2nd March 2015!

The 3rd CHiME Speech Separation and Recognition Challenge

Supported by IEEE ASRU 2015

Following the success of the 2011 and 2013 CHiME challenges it gives us great pleasure to pre-announce the 3rd CHiME Speech Separation and Recognition Challenge (CHiME-3)

CHiME-3 will be an official IEEE ASRU 2015 Challenge Task. Participants will be invited to submit CHiME-3 papers to the ASRU workshop to be held in Scottsdale, Arizona 13-17 December. Papers will be presented at a Special Session.

The Task

The CHiME-3 scenario will be ASR for a multi-microphone tablet device in everyday, noisy environments. It will represent a significant step forward in terms of both realism and difficulty with respect to the previous CHiME challenges.

The challenge will feature: To maintain compatibility with the 2nd CHiME challenge, the new challenge will re-use the WSJ evaluation framework. Utterances will be provided embedded in continuous audio with ground truth VAD annotations.


Some samples and recording details are available here.


At time of launch in February we will provide:

As with previous CHiME challenges we invite participation from both the signal processing and the speech recognition communities. To support teams who lack access to the necessary GPU infrastructure required to run the evaluation system, we will offer 'remote evaluation' as a service.
