Abstract
By using a structured vocabulary where subsets of a total large vocabulary are used for speech recognition to control an ultrasound machine, recognition performance is improved. Where the subsets of voice commands are selected to fit the state of the ultrasound machine so as to afford complete control of the machine, little or no degradation of the control of the machine will result. A two-way communication link between the voice control system and the ultrasound machine permits the monitoring of the state of the ultrasound machine so that subsets of the total vocabulary may be made active. From knowledge of the state of the ultrasound machine, dynamic macros may be implemented for streamlined control of the ultrasound machine. A two-way communication link between the voice control system and the ultrasound machine permits simultaneous control by means of, but not limited to, voice control, keyboard and foot-switch.
