CHiME-6

Following the success of the 1st, 2nd, 3rd, 4th and 5th CHiME challenges we are pleased to announce the 6th CHiME Speech Separation and Recognition Challenge (CHiME-6). The new challenge will consider the problem of distant multi-microphone conversational speech diarization and 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 CHiME-2020 VIRTUAL WORKSHOP

The results of CHiME-6 will be presented at a dedicated virtual workshop that will take place on May 4th. Details are available on the workshop website.

MATERIALS

CHiME-6 features two tracks:

  1. Multiple-array speech recognition
  2. Multiple-array diariazation and recognition

These two tracks are reruns of CHiME-5 and DIHARD II, respectively, with the following key differences:

  • an accurate array synchronization script is provided,
  • the impact of diarization error on speech recognition error will be measured,
  • upgraded, state-of-the-art baselines are provided for diarization, enhancement, and recognition.

Participants are able to submit to either one track or both.

On this web site you will find everything you need to get started, including,

  • a task overview providing details of the motivation and recording set up,
  • For both Track 1 and Track 2
    • a description of the training, development and evaluation datasets,
    • baseline recognition and evaluation tools,
    • a detailed description of the challenge rules,
    • instructions on how to submit your results,
  • a download center with links to all tools and data packages.
