Speech and Music Specialization (IMAGE) McGill University Caption Figure shows original song (bottom left) and its spectrogram (above it, in blue). This spectrogram can be decomposed according to the amount of energy contained in spectral and temporal modulation rates (central panel). Auditory cortex on the right and left sides of the brain (right side of figure) decode melody and speech, respectively, because the melody depends more on spectral modulations and the speech depends more on temporal modulations.
