Previous studies have shown that speech spoken by someone familiar is more intelligible than an unfamiliar voice in the presence of a competing talker. Although the voices of friends or family members were the familiar voices in these previous studies, other studies have shown that one’s own recorded voice is more familiar than others’ voices. However, the intelligibility of one’s own recorded voice still remains unclear. The aim of this study is to investigate the intelligibility of one’s own recorded voice compared with the voices of others. We conducted a large-scale online Japanese version of the coordinate-response-measure (CRM) task including one’s own and others’ recorded voices with 137 Japanese participants. The results showed that one’s own recorded voice is more intelligible than others’ voices when there is a competing talker. We also analyzed the relationship between the performance of the CRM task and impressions of one’s own recorded voice. The results indicated that the intelligibility benefit of one’s own recorded voice was significantly greater for participants who rated their own recorded voice higher in terms of similarity or intelligibility compared with those who rated it lower.
