CFP: 2nd CHiME Challenge and Workshop - deadline extension to 29th Jan

     2nd CHiME Speech Separation and Recognition Challenge
Supported by the IEEE AASP, MLSP and SLTC Technical Committees

                 2nd International Workshop on
  Machine Listening in Multisource Environments (CHiME 2013)

              Extended Deadline: January 29, 2013
           Workshop: June 1, 2013, Vancouver, Canada




The final deadline for the Challenge and the Workshop will be January 29, 2013.


The challenge consists of recognising distant-microphone speech mixed in
two-channel nonstationary noise recorded over a period of several weeks
in a real family house. Entrants may address either one or both of the
following tracks:

* medium vocabulary track: WSJ 5k sentences uttered by a static speaker
* small vocabulary track: simpler commands but small head movements

You will find everything you need to get started (and even more) on the
challenge website:
- a full description of the challenge,
- clean, reverberated and multi-condition training, development and test data,
- baseline training, decoding and scoring software tools based on HTK.
Any approach is welcome, whether emerging or established.

Submission consists of a 2- to 8-page paper describing your system and
reporting its performance on the development and test datasets.
If you are interested in participating, please email us so we can
monitor interest and send you further updates about the challenge.

The best challenge papers will distinguished by an award from the
Industrial Board.


Following the success of the 1st CHiME Workshop in 2011, we are 
organizing a second edition that will be held in conjunction with ICASSP 
2013. CHiME 2013 will consider the challenge of developing machine 
listening applications for operation in multisource environments, i.e. 
real-world conditions with acoustic clutter, where the number and nature 
of the sound sources is unknown and changing over time. CHiME will bring 
together researchers from a broad range of disciplines (computational 
hearing, blind source separation, speech recognition, machine learning) 
to discuss novel and established approaches to this problem. The 
cross-fertilisation of ideas will foster fresh approaches that 
efficiently combine the complementary strengths of each research field.

The workshop will feature two keynote speakers:

* Daniel P.W. Ellis, Columbia University
* Steven J. Rennie, IBM


We invite original submissions in the form of either extended abstracts 
or full papers. Relevant research topics include (but are not limited to):

* automatic speech recognition in multisource environments,
* acoustic event detection in multisource environments,
* sound source detection and tracking in multisource environments,
* music information retrieval in multisource environments,
* sound source separation or enhancement in multisource environments,
* robust feature extraction and classification in multisource environments,
* scene analysis and understanding for multisource environments.
