Abstract
A system for controlling a sewing machine includes a drive unit including a motor for driving the sewing machine, a brake unit including a brake for stopping the sewing machine, detection means for detecting operational states of the sewing machine, and input means for supplying operation commands to the sewing machine. The input means converts a plurality of sounds voiced by the operator into predetermined speech signals and issues such signals to a control unit to enable the latter to produce operation command signals corresponding to the speech signals for controlling the drive unit and the brake unit.
