The ability to produce accurate speech sounds in rapid succession is something we humans take for granted. In fact, speech production is an extremely involved process. Thoughts must be translated into linguistic representations (itself not a trivial feat), which are then sent to speech mechanisms that can coordinate, initiate, modify and execute the articulation of an utterance. Through the study of patients with disorders affecting this complex process, we have come to learn that numerous brain areas are recruited in speech production and that they hang in a precarious balance that is easily affected by neurological disease and dysfunction.
The coordination of articulatory movements, an end-stage component of speech production, has received increased attention in recent years. In order for sounds to be produced correctly, the lips, tongue, jaw, velum and larynx must make accurate movements at the right time or the
