Abstract

A total of 156 introductory psychology students heard a taped voice of a mock kidnapper for either 30 seconds or 8 minutes. The kidnapper had either a distinctive voice or a non-distinctive voice, and spoke either in a whisper or in a normal tone of voice. Voice identification from six-person, tape-recorded lineups was tested 2 days later. Participants who initially heard the perpetrator speak in a normal tone were tested with normal tone lineups. Participants who initially heard the perpetrator speak in a whisper were tested either with whispered lineups or normal tone lineups. Results showed that identification performance was superior with longer voice-sample durations. Voice disguise through whispering, distinctiveness of suspect's voice, and changes in tone of voice from initial hearing and lineup test significantly influenced identification performance on both suspect-present and suspect-absent lineups. Small but significant accuracy-confidence correlations were found in both suspect-present and suspect-absent lineups. Duration estimations of the length of the speaker's voice-sample were overestimated, particularly for the short 30-second voice sample.
