Activities

The aim of the Audio Processing Cell is to develop tools and methods for solving real world problems related to audio signals, and speech signals in particular. Our team has been active in speech segmentation and intelligibility enhancement, as well as redundancy detection in audio streams. We are now tackling the problem of information retrieval from spoken sources, with a special interest in Language Identification.

Research projects
