The 3rd CHiME challenge is now complete. Final results were presented at a special session at the IEEE ASRU conference on 17th December 2015. Please visit the results page for a full overview of the performance of the 26 systems submitted.

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). The new challenge is designed around the popular Wall Street Journal corpus and features talkers speaking in challenging noisy environments recorded using a 6-channel tablet based microphone array.

All approaches are welcome, whether they are emerging or established, and whether they rely on speech processing, signal separation or machine learning.

CHiME-3 is 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. All challenge participants will be given the opportunity to present their systems during an ASRU special CHiME Challenge session.
