Abstract
A voice control system for controlling execution of a computer program includes a microphone (10) operative to receive voice commands having the output thereof connected to a clipping circuit (12) which amplifies and clips the microphone output to generate a zero-crossing signal. The output of circuit (12) is connected to a microprocessor (14) which on detecting speech input interrupts program execution in a CPU (15) and 'freezes' display device (16) on which the game is displayed. Microprocessor (14) then processes the input signal to recognize the voice command by determining the relative frequency content of discrete portions of the command. Once it has recognized the command, microprocessor (14) prompts the CPU (15) to execute the command and resume execution of the game program at the point of interrupt. By suspending the progress of the game during the speech input and recognition interval, the voice control system minimizes the time-constraint problems associated with voice input.
