As previously stated, we trained the decoders using single-speaker data. These same decoders could then be used to reconstruct spectrograms from the M-T experiment (5). Determining to whom the subject is attending requires correlation analysis, commonly using Pearson’s r value (6, 36). Typically, the spectrogram that has the largest correlation with the reconstructed spectrogram is considered the attended speaker. We used window sizes ranging from 2 to 32 s to calculate correlations (in logarithmically increasing sizes). We defined decoding accuracy as the percentage of the segments in which the reconstructions had a larger correlation with the attended spectrogram than with the unattended spectrogram.
