This prospective, three-arm randomized controlled trial aims to evaluate the effects of AI-generated maternal voice storytelling on the perioperative stress response, emergence delirium, anesthetic requirements, and perioperative physiological parameters in children undergoing elective adenotonsillectomy. Participants will be randomly assigned to receive AI-generated maternal voice storytelling, relaxing instrumental music, or standard perioperative care. Standardized anesthesia protocols will be used in all groups, and perioperative outcomes will be compared among the three study arms.
