| 1. A voice control system that recognizes a speech uttered by a user to thereby control a device that has a plurality of operating
states, comprising:
a storing unit for storing speech recognition data including a plurality of reference commands;
a speech recognizing unit for recognizing the speech as a recognized reference command included in the reference commands
stored in the storing unit;
a detecting unit for detecting a certain operating state of the device; and
a substituting unit for determining whether each of the reference commands recognized by the speech recognizing unit is a
selectable reference command that can be selected in the certain operating state, and for substituting, when the recognized
reference command is determined to be not the selectable reference command, one of the selectable reference commands for the
recognized reference command,
wherein, when the recognized reference command is one of a reciprocal pair of two reference commands that are for working
oppositely to each other and the recognized reference command is determined to be not the selectable reference command, the
substituting unit substitutes the other of the reciprocal pair for the recognized reference command.
