摘要： A hearing device configured to be worn by a user comprises a) an input unit providing a multitude of electric input signals, each comprising a target signal component and a noise signal component; b) an own voice detector configured to provide an own voice control signal indicative of whether or not, or with what probability, a given electric input signal, originates from the voice of the user. The own voice detector comprises b1) a beamformer unit comprising b1.1) a target maintaining, reference beamformer configured to leave signal components from a fixed target direction un-attenuated or less attenuated relative to signal components from other directions, and providing a current reference signal; and b1.2) a target cancelling beamformer configured to attenuate signal components from said target direction, whereas signal components from other directions are attenuated less relative to signal components from said target direction, and providing a current target cancelling signal. The fixed target direction is a direction from the hearing device towards the user's mouth and the target signal is the user's own voice. The own voice detector further comprises c) a controller for determining the own voice control signal in dependence of the current reference signal and the current target cancelling signal.

The environment sound at a given microphone comprises a mixture of a) a target sound signal s m (n) propagated via an acoustic propagation channel from a direction to or a location ( θ ) of a target sound source to the m th microphone of the hearing aid when worn by the user, and b) possible additive noise signals ν m (n) as present at the location of the m th microphone, wherein the acoustic propagation channel is modeled as x m ( n ) = s m ( n ) h m ( θ ) + ν m ( n ), and wherein h m ( θ ) is an acoustic impulse response for sound for that acoustic propagation channel. The hearing aid system comprises A) a processor connected to said number of microphones, and B) a database Θ comprising a multitude of dictionaries Δ p , p =1, ..., P , where p is a person index, of vectors, termed ATF-vectors, whose elements ATF m , m =1, ..., M, are frequency dependent acoustic transfer functions representing direction- or location-dependent ( θ ), and frequency dependent ( k ) propagation of sound from a direction or location ( θ ) of a target sound source to each of said M microphones, k being a frequency index, k =1, ..., K, where K is a number of frequency bands, when said microphone system is mounted on a head at or in an ear of a natural or artificial person (p'), and wherein each of said dictionaries Δ p comprises ATF-vectors for a given person ( p ) for a multitude of different directions or locations θ j , j =1, ..., J , relative to the microphone system.
