At 514, the content management engine 506 may receive and process the request including the audible input and/or a textual representation of the audible input. Both will be referred to as “the command” for brevity. As part of the processing of the request, the content management engine 506 may identify whether the command relates to a previously received command. If the command does not relate to a previous command, the content management engine 506 may forward the request to the service provider computer 508. Alternatively, if the command does relate to a previous command, the content management engine 506 may identify particular content related to the command and/or user devices related to the command based at least in part on the state information for the user account. By way of example, the command “play songs by [Artist A]” may be used with the state information to determine that the command does not relate previously received input and/or previously played content. In this example, content management engine 506 may utilize a predefined rule set to identify that the phrase “plays songs” indicates a new command that does not relate to previous inputs and/or previously played content. In some embodiments, the content management engine 506 may determine that the command does not relate to previously played content by identifying that the state information does not include any indication that content associated with Artist A has previously been requested and/or presented at any of the user devices associated with the user account (at least for the period of time to which the state information relates).
