October 2010: CHiME update -- CHiME Challenge

With addition support from the EU PASCAL machine learning network, the CHiME Speech Separation and Recognition challenge has been launched. A web site have been constructed containing data and instructions for participants.

May 2010: CHiME update -- data collection complete

Phase 1 and Phase 2 of the CHiME recordings are now complete. The complete data set constitutes around 50 hours of recording. 5 hours from the living room and dining room of the Phase 1 house, and 20 hours each from the living room and kitchen of the Phase 2 house. The complete data is available on demand.

January 2010: CHiME update -- phase 2 data collection

Phase 2 of the CHiME recordings has commenced. Phase 2 aims to record a larger amount of data (10 hours per environment) from two more rooms: a living room and a kitchen in a slightly larger house. The recordings will be completed during February and postprocessed in time for the official release of the CHiME corpus in April.

December 2009: CHiME update -- baseline ASR results

The CHiME evaluation framework has been established. Grid corpus sentences are being convolved with room responses and mixed into CHiME corpus. Recognition tasks involving both segmented and unsegmented utterances have been defined. Baseline performance of speech fragment decoding and soft missing data recognition systems has been established for the monaural condition

October 2009: CHiME update -- phase 1 data collection

The first phase of the audio recording is complete. Data includes approximately 10 hours of 96 kHz binaural audio data recorded in a domestic living room and a domestic dining room. A set of room impulse response measurements have been made to allow extra sources to be artificially mixed into the recordings.

August 2009: CHiME update -- recording set up

The hardware and software infrastructure for the CHiME corpus collection is complete and the first phase of audio recordings is due to commence. Recordings will be made using a B&K binaural manikin and recorded directly onto a laptop hard drive via a MOTU firewire A-D unit.

June 2009: CHiME kicked off

The CHiME project started on the 1st June 2009. Activity in the first year will focus on designing the audio recording set-up, data collection, developing the ASR evaluation framework and generating baseline ASR results.
