  • Publication number: 20220189458
    Abstract: Systems, methods, and devices for verifying a user are disclosed. A speech-controlled device captures a spoken command, and sends audio data corresponding thereto to a server. The server performs ASR on the audio data to determine ASR confidence data. The server, in parallel, performs user verification on the audio data to determine user verification confidence data. The server may modify the user verification confidence data using the ASR confidence data. In addition or alternatively, the server may modify the user verification confidence data using at least one of a location of the speech-controlled device within a building, a type of the speech-controlled device, or a geographic location of the speech-controlled device.

  • Patent number: 10733987
    Abstract: Systems, methods, and devices related to providing content items from a collection of content items. The embodiments disclosed enhance user experience by keeping track of which content items were already played to a user, and skipping those content items automatically. The embodiments disclosed herein also can enable a user to limit playing of content items to those that have been added since the last time contents items from the collection of content items were played. If the user selects to receive additional content items after receiving the newly added items, the system can provide the older unplayed content items after the newly added content news items have been played.

  • Patent number: 9697051
    Abstract: An approach is provided for providing services via cloud based analytics. An analytics platform determines one or more data propagation policies associated with propagating user information from at least one device to one or more cloud components. The analytics platform also processes and/or facilitates a processing of the one or more data propagation policies to cause, at least in part, a propagation of the user information to the one or more cloud components, wherein the propagation causes, at least in part, the user information to be available to one or more applications, one or more services, or a combination thereof.
