Timeline of trials in Experiment 1. Each trial began with a 500 ms auditory tone, followed by 500 ms of blank screen. The statement to be spoken or sung was then presented. In the song condition, the melody was also sounded. A pre-vocal count-in timer was then presented. Participants began vocalization with the appearance of the green circle. Additional movements were captured during the post-vocal epoch (blank screen). The trial ended with a 500 ms auditory tone. Facial motion and acoustic information was captured throughout the entire trial timeline.
