Objectives:

As a follow-up to the workshop held in 2010 at the UCL Gatsby computational neuroscience
unit, this workshop further promotes and facilitates interaction between researchers in
Psychoacoustics, Auditory Physiology and Machine Audition to stimulate joint efforts
towards a better understanding of acoustic information processing in challenging conditions
characterized by noise and reverberation. We believe that a breakthrough in the understanding
of human Auditory Scene Analysis (ASA) and Computational Auditory Scene Analysis
(CASA) can only be expected by multidisciplinary collaboration.

Topics:

- Physiological and psychological basis of Auditory Scene Analysis (ASA)
- Models of ASA: Computational Auditory Scene Analysis (CASA)
- Perceptual aspects of automatic Speech Recognition (ASR)
- Machine learning approaches to CASA
- Music information retrieval
- Models of speech (e.g., as used in Speech Synthesis)
- Language modeling
