1. A method of automatic speech recognition (‘ASR’), the method implemented with a speech recognition grammar of a multimodal application, with the multimodal application operating on a multimodal device supporting multiple modes of user interaction with the multimodal application, the modes of user interaction including a voice mode and a visual mode, the multimodal application operatively coupled to a grammar interpreter and configured to enable a user of the multimodal application to select or deselect multiple items in a selection list using a single utterance, the method comprising: accepting, by the multimodal application, speech input corresponding to the single utterance for selecting or deselecting one or more items in the selection list; providing, from the multimodal application to the grammar interpreter, the speech input and a speech recognition grammar associated with the selection list; receiving, by the multimodal application from the grammar interpreter, interpretation results, the interpretation results including at least one matched word from the grammar that identifies at least one item in the selection list and a separate indication of whether to select or deselect the at least one item in the selection list, wherein the separate indication is based, at least in part, on the speech input; and selecting or deselecting based, at least in part, on the separate indication, the at least one item in the selection list that corresponds to the at least one matched word.
