An online algorithm for echo cancellation, dereverberation and noise reduction based on a Kalman-EM Method

Abstract Many modern smart devices are equipped with a microphone array and a loudspeaker (or are able to connect to one). Acoustic echo cancellation algorithms, specifically their multi-microphone variants, are essential components in such devices. On top of acoustic echos, other commonly encounter...
