Zusammenfassung: | A hearing device comprises at least one first, outward-facing, input transducer configured to pick up first sounds from the environment of a user and a second, inward-facing, input transducer configured to pick up a second sounds at the eardrum of the user the first and second input transducers providing first and second electric input signals representative of said first and second sounds, respectively. The hearing device further comprises a directional system configured to receive the at least one first and said second electric input signals and comprises a) an own voice beamformer configured to provide an estimate of the user's own voice in dependence of the at least one first and the second electric input signals and configurable own voice beamformer weights; b) and an own voice analyzer configured to analyze at least one of the at least one first and said second electric input signals, or to analyze a signal or signals originating therefrom, and to provide an own voice beamformer weight control signal. The own voice analyzer comprises b1) an own voice detector configured to estimate whether or not, or with what probability, a given input signal representative of sound originates from the voice of the user of the system, and to provide an own voice control signal indicative thereof; b2) an own voice classifier configured to classify, in dependence of the own voice control signal, an utterance from the user in at least two classes and to provide an own voice classification signal; and b3) an own voice beamformer controller configured to control the configurable own voice beamformer weights in dependence of the own voice classification signal, and providing the own voice beamformer weight control signal. A method of operating a hearing device, e.g. a hearing aid, is further disclosed. |
