Abstract: A method of audio feedback and/or visual feedback therapy includes providing a microphone operatively associated with an audio delay unit, a plurality of trans-cutaneous nerve stimulation electrodes and a power supply. A patient speaks into the microphone thereby causing a responsive electrical signal representative of the patient's speech to pass through an audio delay which may be variable as to duration of delay and deliver the electrical feedback signals to the patient. Audio feedback and/or visual feedback may also be provided to the patient. Corresponding apparatus is disclosed.
