A practical beamformer-postfilter system for adaptive speech enhancement in non-stationary noise environments

In this contribution we present an adaptive beamformer-postfilter system which can be used to suppress non-stationary noises. The emphasis lies on the spatial filtering property

A generalized view on microphone array postfilters

In this paper a generic transfer function for microphone array postfilters is derived and discussed. This function comprises a matrix which can be designed freely

Speaker activity detection for distributed microphone systems in cars

In this contribution a new framework for energy-based acoustic speaker activity detection for distributed microphones in automotive environments is presented. The method relies on the

Robust adaptive cancellation of interfering speakers for distributed microphone systems in cars

Hands-free systems in cars aim to capture the speech of different speakers at the best. Therefor distributed microphones can be aligned to each of these

Detection of local disturbances and simultaneously active speakers for distributed speaker-dedicated microphones in cars

For automotive hands-free and speech recognition applications, distributed microphones are often mounted in the car where each of the speakers has a dedicated microphone close
