Earwitnesses: The effect of voice differences in identification accuracy and the realism in confidence judgments

• Individual characteristic features in voice and speech are important in ear witness identification. A target-absent lineup with six foils was used to analyze the influence of voice and speech features on recognition. The participants’ response for two voice foils were particularly successful in the sense that they were most often rejected. These voice foils were characterized by the features’ articulation rate and pitch in relation to the target voice. For the same two foils the participants as a collective also showed marked underconfidence and especially good ability to separate correct and incorrect identifications by means of their confidence judgments for their answers to the identification question. For the other four foils the participants showed very poor ability to separate correct from incorrect identification answers by means of their confidence judgments.
