The human ability to recognise a voice is important for social interaction and speech comprehension. In everyday recognitions, the voice can be encountered alone (e.g. over a telephone) or with a face, and ~e person being recognised can be familiar or unfamiliar (such as a witness choosing a perpetrator from a lineup). This thesis - presents 7 studies cov~ring each of these situations. The first paper presents 3 studies on recognition of unfamiliar voices when there is a change in emotional tone between learning and test phases. A tone change reduces recognition accuracy when there is no specific encoding strategy at the learning phase. Familiaris.ation at the learning phase reduces the tone change effect but concentrating on word content at the learning phase does not. The second paper presents 3 studies investigating the limitations of the face overshadowing effect (voice recognition is worse when the voice is learned with a face than if it is learned alone). Blurring faces made face recognition more qifficult but did not affect voice recognition. In experiment 2, participants learned a sentence repeated 3 times, either with the face changing on each repetition or staying the same. Face recognition accuracy was lower when there were 3 faces, but this did not affect voice recognition. In experiment 3, inverting faces' made face recognition more difficult but did not affect voice recognition. The third paper reports that episodic memory for a celebrity is improved when a face and voice are given compared to just a face. A model of person recognition is presented that builds on existing models (e.g. Burton, Bruce & Johnston, 1990; Belin, 2004). It accounts for unfamiliar and familiar voice recognition and the benefits and costs of auditory-visual integration.
