Example spectrograms for the same talker, same utterance condition: recorded own voice signal of talker 2 at the entrance of the occluded ear canal (top left) and recorded in-ear own voice signal (top right) of talker 2, and the simulated in-ear own voice signals estimated by the speech-independent individual (middle left) and speech-independent talker-averaged (middle right), and the speech-dependent individual (bottom left) and speech-dependent talker-averaged (bottom right) models.
