| description | 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. |
