Abstract: A hearing aid includes an input providing an input signal representing sound in an environment, the input signal including no speech signal, or one or more speech signals from one or more speech sound sources and additional signal components, termed noise signal, from one or more other sound sources, an own voice detector, a voice activity detector, and a talker extraction unit to determine and/or receive one or more speech signals as separated one or more speech signals from speech sound sources other than the hearing aid user and to detect the speech signal originating from the voice of the user. The talker extraction unit provides separate signals, each including, or indicating presence of, one of the one or more speech signals. A noise reduction system determines speech overlap and/or gap between the speech signal originating from the user's voice and each of the separated one or more speech signals.

Abstract: A hearing aid system comprises a hearing aid configured to be worn on the head at or in an ear of a user. The hearing aid comprises a microphone system comprising a multitude of M of microphones arranged in said hearing aid and adapted to provide M corresponding electric input signals xm(n), m=1, . . . , M, n representing time. The environment sound at a given microphone comprises a mixture of a) a target sound signal sm(n) propagated via an acoustic propagation channel from a direction to or a location (?) of a target sound source to the mth microphone of the hearing aid when worn by the user, and b) possible additive noise signals vm(n) as present at the location of the mth microphone, wherein the acoustic propagation channel is modeled as xm(n)=sm(n)hm(?)+vm(n), and wherein hm(?) is an acoustic impulse response for sound for that acoustic propagation channel.
