The 5th CHiME Speech Separation and Recognition Challenge

News - 10th September

Results of the CHiME-5 challenge are now available.

Following the success of the 1st, 2nd, 3rd, and 4th CHiME challenges we are pleased to announce the 5th CHiME Speech Separation and Recognition Challenge (CHiME-5). The new challenge will consider the problem of distant multi-microphone conversational speech recognition in everyday home environments. Speech material was elicited using a dinner party scenario with efforts taken to capture data that is representative of natural conversational speech.

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


The results of CHiME-5 will be presented at a dedicated workshop that will take place on September 7th in Hyderabad following Interspeech 2018. Further details are available on the workshop website.

The workshop will be held at the Microsoft Campus close to the Interspeech conference centre.


CHiME-5 features two tracks depending on the number of microphone arrays available for testing:

  • single-array track
  • multiple-array track
Participants are encouraged to submit results for all tracks. Submitting results for one track is also allowed.
