Crosstalk data detection method and electronic device

One or more computer readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• receiving a first audio data block and a second audio data block, wherein the first audio data block and the second audio data block separately include a plurality of audio data segments;
• calculating correlation coefficients between audio data segments of the first audio data block and corresponding audio data segments of the second audio data block to obtain a plurality of peak values of the correlation coefficients;
• setting time differences between acquisition times of the audio data segments of the first audio data block and acquisition times of the corresponding audio data segments of the second audio data block as audio segment time differences;
• setting a first time difference and a second time difference of the audio segment time differences corresponding to a first peak value and a second peak value as a reference time difference and a crosstalk time difference respectively, the crosstalk time difference being larger than the reference time difference;
• determining that a corresponding audio data segment of the first audio data block includes crosstalk data when an associated audio segment time difference matches the crosstalk time difference and does not match the reference time difference;
• and
• removing the corresponding audio data segment including the crosstalk data from the first audio data block.

An electronic device, comprising:

• a first sound sensing device configured to generate a first audio data block, the first audio data block including a plurality of audio data segments;
• a second sound sensing device configured to generate a second audio data block, the second audio data block includes a plurality of audio data segments;
• and
• a processor configured to:
• calculate correlation coefficients between the plurality of audio data segments of the first audio data block and the plurality of audio data segments of the second audio data block to obtain a plurality of peak values of the correlation coefficients,
• set time differences between acquisition times of the audio data segments of the first audio data block and acquisition times of the corresponding audio data segments of the second audio data block as audio segment time differences,
• set a first time difference and a second time difference of the audio segment time differences corresponding to a first peak value and a second peak value as a reference time difference and a crosstalk time difference respectively, the crosstalk time difference being larger than the reference time difference,
• determine that a corresponding audio data segment of the first audio data block includes crosstalk data when an associated audio segment time difference matches the crosstalk time difference and does not match the reference time difference, and
• remove the corresponding audio data segment including the crosstalk data from the first audio data block.
