1. A pacemaker system for a human subject having spasmodic dysphonia, the system comprising: a sensing electrode configured to detect voice activity of the subject and to generate a first signal; a processor, in communication with the sensing electrode, configured to receive the first signal and to generate at least one stimulation parameter based on the first signal in order to activate a glottic closure reflex and to stimulate a recurrent laryngeal nerve or vagus nerve of the subject; a mechanical actuator configured to receive the at least one stimulation parameter and to activate the glottic closure reflex of the subject based on the at least one stimulation parameter; and a stimulating electrode configured to receive the at least one stimulation parameter and to activate the recurrent laryngeal nerve or the vagus nerve of the subject based on the at least one stimulation parameter.
