From: Towards reconstructing intelligible speech from the human auditory cortex

Deep neural network architecture (A) An original auditory spectrogram of a speech sample is shown on top. The reconstructed auditory spectrograms of the four models are shown below. (B) Magnitude power of frequency bands during an unvoiced (t = 1.4 sec) and a voiced speech sound (t = 1.15 sec, shown with dashed lines in A) for original (top) and the four reconstruction models.
