Research on perception of emotional voices has greatly advanced in the past decades. However, our understanding of emotional vocal production remains insufficient. This fMRI study explores the brain correlates (especially within the insular cortex) of emotional vocalisation thanks to a pseudo-word production task. The experiment uses a novel methodology consisting of MRI-compliant accelerometers to measure voice-induced vibrations (VIV). In an embodied framework, these vibrations should be processed by the brain as part of emotional vocalisation, as well as bring about feelings of agency. Insular activations are reported for emotion vs. neutral productions. Moreover, insular activation correlates with voice-induced vibrations for whispered phonation when compared to non-phonated conditions. These findings show the feasibility and theoretical relevance of accelerometric measurements for the study of vocal production. They suggest interesting new possible endeavours for affective neuroscience, and cognitive sciences in general.
