A system for the control of a medical implant in a mammal body , said system comprising a first and a second part being adapted for communication with each other, in which system the first part is adapted for implantation in the mammal body for the control of and communication with the medical implant , the second part is adapted to be worn on the outside of the mammal body in physical contact with said body and adapted to receive control commands from a user and to transmit these commands to the first part , wherein the system is adapted to use the mammal body as a conductor for communication between the first and the second parts, wherein the second part is adapted to receive and recognize the control commands from a user as voice commands and is adapted to transform recognized voice commands into signals which are transmitted to the first part via the mammal body as a conductor for the control of said implant , the first part being adapted to convey such signals to the implant , characterized in that said system is adapted to receive voice commands comprising a complex of different frequencies and adapted to translate said voice commands into one fixed defined output command, said output commands are adapted to summarise a defined input of different frequencies into one single action, wherein said system comprises a first conducting plate in the first part of the system and a second conducting plate in the second part of the system, the system being adapted to create an electrical capacitive field with potential differences between said first and second conducting plates, in which the second part is arranged in a device adapted to be in contact with the skin of the mammal body , so that the electrical field will propagate between the first and second parts by means of the mammal body, wherein the system is adapted to transmit commands between the first and second parts using variations in said electrical capacitive field. wherein the system is adapted to use the mammal body as a conductor for communication between the first and the second parts, wherein the second part is adapted to receive and recognize the control commands from a user as voice commands and is adapted to transform recognized voice commands into signals which are transmitted to the first part via the mammal body as a conductor for the control of said implant , the first part being adapted to convey such signals to the implant , characterized in that said system is adapted to receive voice commands comprising a complex of different frequencies and adapted to translate said voice commands into one fixed defined output command, said output commands are adapted to summarise a defined input of different frequencies into one single action, wherein said system comprises a first conducting plate in the first part of the system and a second conducting plate in the second part of the system, the system being adapted to create an electrical capacitive field with potential differences between said first and second conducting plates, in which the second part is arranged in a device adapted to be in contact with the skin of the mammal body , so that the electrical field will propagate between the first and second parts by means of the mammal body, wherein the system is adapted to transmit commands between the first and second parts using variations in said electrical capacitive field. <EOS>
