When he's healing from an injury, he asks his robots to play a recording of his Kryptonian parents because he finds it soothing, even though it's just a partial recording.
At the end of the movie, after he sees the rest of his parents' message and learns they wanted him to take over the planet and breed with the women, and after he goes back to his adopted parents' farm to rejuvenate before the final battle, he ends up back in the fortress again to heal, but this time he has the robots play a recording of his childhood with the Kents.
