Audio device and method of audio processing with improved talker discrimination

An audio device with improved talker discrimination, the audio device comprising at least

• a first audio input to receive a first voice input signal;
• a second audio input to receive a second voice input signal;
• a first filter bank circuit, configured to provide a plurality of first sub-band signals from the first voice input signal;
• a second filter bank circuit, configured to provide a plurality of second sub-band signals from the second voice input signal;
• a correlator circuit, configured to determine at least one signal correlation between at least a group of the first sub-band signals and at least a group of the second sub-band signals;
• an attenuator circuit, arranged to receive at least the group of the first sub-band signals and configured to conduct signal attenuation on the group of the first sub-band signals to provide gain-controlled sub-band signals, wherein the signal attenuation is based on the determined at least one signal correlation and corresponds to a normal operation threshold;
• an audio output circuit, configured to provide a voice output signal from at least the gain-controlled sub-band signals;
• and
• a silence detector circuit connected with the attenuator circuit, which silence detector circuit is configured to control the attenuator circuit and set the signal attenuation to a common silence threshold that is higher than the normal operation threshold when voice silence is determined.
