Central nervous system control of the laryngeal muscles in humans
Studies of laryngeal muscle control for respiration, voice and speech, cough .. of the fundamental frequency that likely reflects the mechanical effects of vocal fold intonation patterns are pre-programmed, a perturbation in auditory feedback .
In fact, a tongue movement task activated the oral facial primary motor region.

Abstract Laryngeal muscle control may vary for different functions such as: This review discusses the control of the human laryngeal muscles for some of these different functions. Sensori-motor aspects of laryngeal control have been studied by eliciting various laryngeal reflexes. The role of audition in learning and monitoring ongoing voice production for speech is well known; while the role of somatosensory feedback is less well understood. Reflexive control systems involving central pattern generators may contribute to swallowing, breathing and cough with greater cortical control during volitional tasks such as voice production for speech.
