1. A method of building a mixed-initiative grammar comprising: responsive to receiving a user input, creating a plurality of sets, wherein each set comprises an association of at least one conjoin phrase and at least one directed dialog grammar, wherein the at least one conjoin phrase, when recognized within a user spoken utterance, indicates that the at least one directed dialog grammar associated with the at least one conjoin phrase is used when processing speech recognized text adjacent to the at least one conjoin phrase within the user spoken utterance; prompting the user to select from among at least two grammar generation techniques, wherein the at least two grammar generation techniques are selected from a group consisting of a fixed order technique, a wide combination technique, and a narrow combination technique; receiving a user input specifying one of the at least two grammar generation techniques; and automatically generating the mixed-initiative grammar, wherein the mixed-initiative grammar specifies an allowable ordering of the plurality of sets corresponding to an allowable ordering of phrases within the user spoken utterance and specifies whether duplicative phrases are allowable within the user spoken utterance in accordance with the selected grammar generation technique.
