Investigations of Verbal Cues and Self-Voice Perception Model

It is of great significance to explore the influence mechanism of verbal cues on self-voice perception under different conditions. The aim of this study is to probe the effects of verbal and non-verbal conditions on implicit task (experiment 1) and explicit task (experiment 2) of self-voice. Binaural auditory channels were used to present two voices successively, and the speakers included the participants, familiar and strangers. In the experiment 1, participants were asked to judge whether the pair of stimuli were pronounced by the same speaker. In the experiment 2, participants were asked to identify whether one of the stimuli was their own voice. The results show that there is no difference in individual voice perception of self (vs. non-self) under different conditions of verbal cues in the implicit task. In the explicit task, there is less accuracy in recognizing the voice of self than that of non-self. It is also found that there exists no difference in individual self-voice perception at different levels of factors.
