Repetition deafness (RD) refers to a reduced performance in reporting a repeated item, compared to a nonrepeated one, during a rapid auditory presentation. We investigated the effects of a vocal difference on RD in order to examine whether an encoding failure was as a cause of RD. The stimuli pronounced by a male and a female were presented binaurally in a serial order. The results showed that RD was observed only under different voice conditions. We propose an alternative hypothesis that an encoding failure is a cause of RD.
