In many speech communication applications, the speech signal recorded using the microphones is corrupted by background noise, interfering speakers and reverberation. This may lead to a significant reduction of speech intelligibility, especially for hearing impaired listeners.

The aim of this project was to develop new multi-channel techniques for spatially distributed microphones that achieve a better speech intelligibility than state-of-the-art methods in adverse acoustic environments (e.g., multiple simultaneous speakers (cocktail party scenario) or large reverberation).

Project B was finished in the first funding period and was no longer funded in the second funding period.
