Voice Identification Over the Telephone1
Authors:A Daniel Yarmey
Abstract:Following a telephone survey investigating attitudes toward police and frequency of personal victimization. 177 citizens between the ages of 18 and 88 years participated without forewarning in a field study on telephone voice identification. Identification accuracy (hits) improved with longer conversation durations (an average duration of 7.8 min compared to conversation durations of 3.2 min and 4.3 min. on average), but the false alarm rate also reliably increased with longer durations in a target-present lineup. False alarms were consistently high (overall M= .48) in the target-absent lineup. No significant differences were found in hit scores or false alarm scores over a two to three day retention interval. No significant correlation was found between confidence scores and accuracy of performance on the target-present lineup (r= .10). but a significant correlation (r= 36) was found on the target-absent lineup.
