(B) If the voice input contains a request for media content, such as for media content to be ultimately played back by the MPS 100, the payload of the response 783 may include information that enables the MPS 100 to request a search for the media content from one or more MCS(es). The payload may be used by the MPS 100 to build request(s) suitable for communicating with and requesting information from an MCS, such as via the Sonos Music API (SMAPI). For example, the MPS 100 may build separate first, second, and third requests suitable to search for content the SPOTIFY, PANDORA, and APPLE MUSIC platforms, respectively. In some instances, the voice input may be a relatively straightforward request that may be readily resolved by the VAS 160 without the VAS 160 having to perform extensive NLU processing and/or Internet searching. Examples of requests include commands to play a particular artist (i.e., “Play George Strait”), play a particular song, play a particular album, etc. In some embodiments, a VAS may determine to “resolve” a request on its own rather than going through the MPS 100. For example, if a user speaks “Play Dave Mathew's Crash on GOOGLE PLAY,” the VAS may directly communicate with one or more MCS(es) without the MPS 100 intervening. In such embodiments, the VAS may resolve requests if certain conditions are met. For example, the VAS may resolve a request in cases where both of the following conditions are satisfied: (i) the request is straightforward and (ii) the media content service is directly supported by the VAS. A media content service may be directly supported by a VAS, for example, when the VAS has an affiliation with the media content service and the user has authorized a link between the media content service and the VAS. An example of a sponsored media content service may be SPOTIFY, which today may be linked with VASes provided by both AMAZON and GOOGLE. In some embodiments, the MPS 100 may intervene between the VAS and the media content service even in cases where the VAS sponsors a media content service, such as when the voice input is relatively less straightforward and/or when MPS intervention is preferred to find and possibly play back media content as described above and in further detail below.
