10. A control method for a speech recognition grammar creating apparatus that describes a speech-recognizing object as a speech recognition grammar, comprising: creating a component group of n component elements, wherein n is an integer not less than 2; determining if the component group on n component elements is a group including at least one component element that cannot be omitted; determining if the n component elements are order designated when it is determined by said first determination unit that the component group is the group including the at least one component element that cannot be omitted; and creating the speech recognition grammar by creating sequences of the n component elements and combinations thereof according to the designated order when it is determined by said second determination unit that the n component elements are order designated, and by creating respective permutations of the n component elements and combinations thereof when it is determined by said second determination unit that the n component elements are not order designated.
