13. A system to provide an integrated, multi-modal, natural language voice services environment having an input device, one or more secondary devices, and a central device configured to: receive a multi-modal natural language input from the input device, wherein the input device initially received the multi-modal natural language input; maintain a constellation model and distribute the constellation model to the input device and the one or more secondary devices, wherein the constellation model describes natural language resources, dynamic states, and intent determination capabilities associated with the input device, the central device, and the one or more secondary devices; aggregate the natural language resources, the dynamic states, and the intent determination capabilities associated with the input device and the one or more secondary devices to converge the natural language resources, the dynamic states, and the intent determination capabilities held across the natural language voice services environment; use the converged natural language resources, dynamic states, and intent determination capabilities held across the natural language voice services environment to determine a preliminary intent associated with the multi-modal natural language input; send the multi-modal natural language input to the one or more secondary devices to invoke the intent determination capabilities associated with the one or more secondary devices; collate intent determination responses received from the one or more secondary devices with the determined preliminary intent to generate an intent hypothesis associated with the multi-modal natural language input on the central device; and return the intent hypothesis associated with the multi-modal natural language input and information relating to one or more requests associated with the multi-modal natural language input to the input device, wherein the input device is configured to invoke one or more actions based on the returned intent hypothesis and the information relating to one or more requests associated with the multi-modal natural language input.
