Abstract A vocal tactile feedback apparatus and method for use in the treatment of stuttering and other speech or hearing abnormalities is disclosed. A microphone and amplifier are utilized to produce and amplify an electronic signal responsive to vocal utterances spoken within a known range of the microphone. The amplified signal is then delayed by a suitable delaying circuit for a desired time interval and is then transmitted to an electro-mechanical transducer attached to the outer surface of the laryngeal or glottis region of the neck of a user. The transducer then transforms the amplified delayed signal into a mechanical vibration to provide delayed vibrotactile feedback of the vocal utterances whether spoken by the user or by others. A unique transducer assembly for use in the apparatus and method is disclosed.
A vocal tactile feedback method for use in the treatment of speech or hearing abnormalities or otherwise enhancing speech operability of a person through providing enhanced awareness of phonatory behavior to the person comprising the steps of providing a microphone for producing an electronic signal responsive to the person's vocal utterances, providing amplifier means for amplifying said electronic signal, delaying said amplified signal with delaying circuit means for a desired time interval, progressively during the overall course of said treatment reducing the duration of said time interval, and providing said delayed signal to an electro-mechanical transducer disposed in contact with an outer surface of the laryngeal region on the neck of the person to provide delayed tactile feedback to the person of the said vocal utterances which may be spoken by the person, whereby the feedback will enhance the awareness of the person of said vocal utterances.
