"Auditory imagery experiences" (AIEs) occur when readers simulate character voices while reading. This project assessed how familiarity with voice and narrative contexts influences activation of AIEs. Participants listened to dialogs between two characters. Participants then read scripts with the characters, half that had been previously listened to and half that were new. During reading, participants were interrupted with an auditory recognition task, with probes presented in voices that either matched or mismatched the character associated with the current line of dialog. Faster responses to matching than mismatching voices were consistently obtained for familiar scripts, providing evidence for AIEs. Transfer to unfamiliar scripts only occurred after extended experience with character voices. These findings define factors that influence activation of speaker voice during reading, with implications for understanding the nature of linguistic representations across presentation modalities.
