HIGHER SPEECH INTELLIGIBILITY WITH APPLICATION OF SEVERAL MICROPHONES ON SEVERAL DEVICES Russian patent published in 2012 - IPC H01L21/02 H04B15/00 

FIELD: information technologies.

SUBSTANCE: according to the proposed solutions, the first audio signal is captured with the help of the first microphone located on a wireless mobile device, besides, the first audio signal represents a sound from multiple sound sources. The second audio signal is captured with the help of the second microphone located on the second device, which is not connected into a wireless mobile device, besides, the second audio signal represents a sound from sound sources. The first and second captured audio signals are processed to generate a signal representing a sound from one of sound sources, separated from a sound of other sound sources. Solutions use different devices, such as Bluetooth sets, wire sets, etc.

EFFECT: higher speech intelligibility, suppression of background noise, detection of speech activity.
