At 512, a request may be transmitted to content management engine 506. The request may include, among other things, the user input and/or any suitable data corresponding to the user input may be transmitted. The user input may include audio captured by the microphone of user device 502. In some embodiments, the request may be received by a routing service (from the user device 502 (or a different intermediate computing component) and processed before being routed to content management engine 506. Any potential intervening component(s) that provide any suitable processing before the request is received by the content management engine 506 may be referred to as “an intermediate computing component(s).” The user device 502 and/or the intermediate computing component(s) may be configured to convert the user input to a different format (e.g., a textual representation of an audible input) and/or to augment the user input. For example, a time stamp indicating a day and/or time at which the user input was received may be added to the request prior to transmission. A device identifier identifying user device 502 may be included in the request. The input “[wake phrase] play songs by [Artist A],” may be modified in some examples to strip the wake word/phrase from the audio and/or a textual representation. Thus, the request transmitted to (or received by) content management engine 506 may include input such as “play songs by [Artist A.”
