ABSTRACT OF THE DISCLOSURE A voice actuated control system suitable for use on a computer numerically controlled (CNC) machine tool includes a pair of radio frequency transmitters and a pair of radio frequency receivers, one of the radio frequency receivers and one of the radio frequency transmitters being located at the machine tool site and the other radio frequency receivers and radio frequency transmitter being carried by the human ma- chine tool operator. Operator-spoken commands are transmitted through the operator's transmitter to the machine tool receiver which outputs an audio signal to a voice interpreter that con- verts the received voice commands into digital signals which are transmitted to the CNC machine tool control system to con- trol machine tool operation. Digital signals generated by the CNC machine tool control system, either in response to received operator commands or in accordance with variations in machine tool operating conditions, are converted by a speech synthe- sizer into synthesized audio signals representing speech phrases indicative of machine tool operating conditions. The speech synthesizer audio signals are transmitted to the operator to audibly inform him or her that the previously transmitted voice commands have been received or that further instructions are required.
