Hearing device configured to utilize non-audio information to process audio signals

A hearing device configured to be worn by a user or to be fully or partially implanted in the head of the user, the hearing device comprising:

• at least one input transducer for converting a sound comprising a target sound from a target talker and possible additional sound in an environment of the user, when the user wears the hearing device, to an electric sound signal representative of said sound,
• an auxiliary input unit configured to provide an auxiliary electric signal representative of said target sound or properties thereof,
• a processor connected to said input transducer and to said auxiliary input unit, said processor being configured to apply a processing algorithm to said electric sound signal, or a signal derived therefrom, to provide an enhanced signal by attenuating components of said additional sound relative to components of said target sound in said electric sound signal, or in said signal derived therefrom, wherein
• said auxiliary electric signal in the form of a vibration signal is derived from a video signal from a camera providing visual information containing information of current mechanical vibrations of a facial or throat region of said target talker originating from the vocal cord of the target talker, and wherein said processing algorithm is configured to use said auxiliary electric signal in the form of a vibration signal or said signal derived therefrom to provide said enhanced signal.
