In some instances, the MPS 100 may send additional messages 782 and receive multiple responses 783 before it ultimately determines the user's intent and the appropriate information to send to the MCS(es) for media content searching (only one message 782 and one response 783 are shown in FIG. 7C). For example, where all or a portion of the utterance is ambiguous, the VAS 160 may request additional information from the MPS 100. This determination may be made with or without the remote computing devices 106a of the VAS 160 first determining the intent. In response, the MPS 100 may retrieve the requested additional information (for example, from a database associated with the MPS's remote computing devices 106d) and send the information back to the VAS 160 for further processing. In some embodiments, the VAS 160 may request more information by including a URI and/or a hyperlink in the response 783 that identifies an action to be taken by the MPS 100 to retrieve the additional information. For example, the URI may be a playlist associated with a media content service. The playlist may be spoken by the user in the initial voice utterance, and the VAS may access the tracks in the playlist, assuming the user and/or the VAS has been granted the appropriate permissions to do so by the MPS 100 and/or the MCS(es) that provide the content within the playlist.
