A multi-channel quality assessment setup applied to a distributed microphone speech enhancement systemwith spectral boosting

For instrumental quality assessment of speech enhancement systems it is common to process the signal components such as speech and noise independently using the filter

Influence of blocking matrix design on microphone array postfilters

In this paper the role of the blocking matrix is investigated in the context of microphone array postfilters. A generic stability criterion, which depends on

Enhanced speaker activity detection for distributed microphones by exploitation of signal power ratio patterns

In cars with integrated distributed microphone systems usually each speaker has a dedicated microphone. An often required broadband speaker activity detection can be performed by

Dynamic signal combining for distributed microphone systems in car environments

Distributed microphone systems in cars usually provide dedicated microphones for several speakers where each micro phone captures the desired speech signal at the best. The

Robust voice activity detection for distributed microphones by modeling of power ratios

In this paper a method for a robust frequency selective voice activity detection (VAD) is presented that evaluates the power ratios between several distributed microphones.
