One's own and similar voices are more attractive than other voices

Objective The aim of the present study was to explore whether people consider their own voice to be more attractive than others and whether the self-enhancement bias of one's own voice could be generalised to other variants of self-voice. Method Two experiments were conducted. In Experiment 1, female and male participants were asked to rate the attractiveness of three types of audio recordings (numbers, vowels, words) from same-sex participants. In Experiment 2, the participants were instructed to rate the attractiveness of six types of audio signals: their own original voice, their recorded voice, a "pitch+20 Hz" audio recording, a "pitch-20 Hz" audio recording, a "loudness+10 dB" audio recording, and a "loudness-10 dB" audio recording. The participants also rated the similarity between the given audio signals and their own voices. Results Experiment 1 showed that the participants rated their own audio recordings as more attractive than others rated their audio recordings, and they rated their own audio recordings as more attractive than those of others. Experiment 2 revealed that the participants rated the recorded voices and the "loudness+/-10 dB" audio recordings as more attractive and similar than the "pitch+/-20 Hz" audio recordings. Conclusions The present study demonstrates that people evaluate their own voices as more attractive than the voices of others and that the self-enhancement bias of voice attractiveness can be generalised to similar and familiar versions of self-voice.
