SYSTEMS AND METHODS OF AUDIO SIGNAL PRODUCTION Russian patent published in 2023 - IPC H04R1/08 H04R1/46 G10L21/208 

FIELD: signal processing.

SUBSTANCE: invention relates to systems and methods for generating an audio signal based on a bone conduction audio signal and an air conduction audio signal. The inventive method includes the steps of obtaining first audio data collected by a bone conduction sensor and second audio data collected by an air conduction sensor, wherein the first audio data and the second audio data represent the user's speech with different frequency components. Next, third audio data is generated based on the first audio data and the second audio data, wherein the frequency components of the third audio data above the frequency point are increased relative to the frequency components of the first audio data above the first frequency point. A plurality of frequency ranges is then determined according to one or more frequency thresholds, wherein the one or more frequency thresholds are determined based on frequency response values of a frequency response curve associated with the first audio data. The first and second weighting coefficients are determined for portions of the first and second audio data located respectively in each of the plurality of frequency ranges, and the third audio data is determined by weighting using the weighting coefficients of the first audio data portion and the second audio data portion. An audio signal generation system and a non-volatile machine-readable storage medium are also claimed.

EFFECT: creation of systems and methods for producing an audio signal with less noise and/or increased quality.
