ADAPTIVE AUDIO ENHANCEMENT FOR MULTICHANNEL SPEECH RECOGNITION Russian patent published in 2019 - IPC G10L15/20 G10L15/16 

FIELD: information technology.

SUBSTANCE: invention discloses means for adaptive shaping of neuron pattern for multichannel speech recognition. A first channel of audio data corresponding to a speech fragment and a second audio data channel corresponding to said speech fragment are received. A first set of filter parameters for a first filter based on a first audio data channel and a second audio data channel and a second set of filter parameters for a second filter based on a first audio data channel and a second audio data channel are generated using a trained recurrent neural network. Generating a single combined audio data channel by combining first channel audio data which has been filtered using first filter, and audio data of second channel, which was filtered using second filter. Audio data are introduced for a single combined channel into a neural network trained as an acoustic model.

EFFECT: high efficiency of speech recognition.
