A highly skilled and dynamic behavior that is organized (at the goal level). Involves a complex interplay between movements various muscles and the sensations that arrive from those movements. But maintains great flexibility in reaching articulatory goals with regard to timing and motion in space. Collection of cells with the same function. Subsystems of the vocal tract can function independently from each other but they can also operate interactively too. The shape of the spaces in the vocal tract influence the sound and acoustic properties of the sound source which is produced by vocal fold (vf) motion (vibrations) voice. The sound from vf vibration is basically a buzz and represents the sound source for. The rest of the vocal tract works to filter that buzz. Some acoustic components are emphasized, others are oppressed.
