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

Effects of resampling in acoustic echo cancellation with static nonlinear loudspeaker distortion

In modern acoustic echo compensation (AEC), nonlinear models are applied to mimic the loudspeaker’s behavior. Many conventional methods disregard the NYQUIST criterion when applying the
