Embodiment in a virtual body that speaks produces agency over the speaking but does not necessarily influence subsequent real speaking.

ABSTRACT: Previous results have shown that body ownership, induced through first-person perspective (1PP) over a virtual body (VB) that moves synchronously with real body movements, can lead to illusory agency over VB utterances even though the participant does not speak. It was also found that when participants later speak they follow the fundamental frequency (FF) of the voice of their VB, indicating a new motor plan for speaking. To eliminate the contribution of veridical agency over the VB movements, we conducted a study where we induced body ownership using visuotactile (VT) synchrony rather than visuomotor. Participants saw a life-sized VB from 1PP and reflected in a virtual mirror, that spoke with corresponding lip movements. Half of the 36 experimental participants experienced synchronous (S
