Abstract

Study of the vocal movements of beatboxing can benefit speech science in a number of ways; but while there are established models of speech motor control that make deterministic predictions about vocal kinematics, little is known about beatboxing motor control. A region of interest method was applied to realtime MRI videos of beatboxing Kick Drums to measure the time to peak velocity—a measurement that is used to assess how well models of speech action predict actual movement trajectories. The average time to peak velocity for Kick Drums is about half of the way (58%) through the total movement duration, similar to the times to peak velocity reported for speech actions. However, while the times to peak velocity for Kick Drums tend to be just above 50%, the times to peak velocity reported for speech sounds are usually a bit below 50%. Further study is needed to assess whether this difference reflects a more extreme constriction goal or a qualitatively different movement pattern.
