Abstract: A hub is configured to provide voice control without assistance from a remote system, which allows the hub to provide a user with the ability to control second devices in an environment by issuing voice commands, even when the hub is unable to communicate with the remote system over a wide area network (e.g., the Internet). The hub is also configured to execute rules without assistance from the remote system, which allows the hub to execute rules, even when the hub is unable to communicate with the remote system over a wide area network (e.g., the Internet).

Abstract: Techniques for decoupling data, sent by a data source, from how the data is sent to a user by a system are described. A system may include an application program interface (API) that enables a data source to simply provide data. The system may determine whether and how to send the data to a user(s) as a notification. The system may determine a modality by which to send the notification to the user. The system may use presence data to determine which device should be used to output the notification to the user. The system may cause the device to output the notification to the user using the modality.

Abstract: Systems, methods, and devices for dynamically authenticating a user are disclosed. A speech-controlled device captures a spoken command, and sends audio data corresponding thereto to a server. The server determines the audio data includes a spoken command to receive content, and therefrom determines a source storing the content. The server also determines threshold user authentication confidence score data associated with the content source. Based at least in part on the threshold user authentication confidence score data, the server determines a user authentication technique, and a device configured to capture user authentication data. The server determines user authentication confidence score data using user authentication data received from the device, and determines weighted user authentication confidence score data therefrom.
