The Effect of Voice Similarity on Stream Segregation

This contribution addresses the influence of voice similarity on a shadowing experiment. Two groups of participants (implicit-knowledge and novelvoice) had to shadow a target voice under two conditions, i.e. (1) when the target voice and the distracter voice were acoustically similar and (2) when they were dissimilar. The error rates did not differ significantly between the two groups, but for both groups, the number of errors was significantly larger in the dissimilarity condition. This demonstrates that voice similarity is a factor to be considered in shadowing experiments.
