Abstract: Synchronized output of audio on a group of devices comprises sending audio data from an audio distribution master device to one or more slave devices in the group. In group mode, a slave can be configured to receive audio data directly from a master device acting as a soft wireless access point (WAP) in an environment that includes a traditional WAP. In response to a user request to output audio via the slave in individual mode, the slave may be configured to dynamically switch to receiving audio data via the WAP in the environment without routing the audio data through the master device acting as the soft WAP. This dynamic switching to receiving audio data via the WAP in individual mode can reduce bandwidth consumption on the master device.

Abstract: Techniques for creating a persistent connection between client devices and one or more remote computing resources, which may form a portion of a network-accessible computing platform. This connection may be considered “permanent” or “nearly permanent” to allow the client device to both send data to and receive data from the remote resources at nearly any time. In addition, both the client device and the remote resources may establish virtual channels over this single connection. If no data is exchanged between the client device and the remote computing resources for a threshold amount of time, then the connection may be severed and the client device may attempt to establish a new connection with the remote computing resources.

Abstract: Systems and methods for device-to-account anomaly detection are disclosed. For example, device information associated with user account data is queried from a user registry and from an external system. The device information from both sources is hashed or otherwise formatted and compared to determine whether a dissimilarity is present. A difference value may be generated and utilized to determine whether an anomaly is present for device-to-account associations as between the user registry and the external system. Utilizing the difference value and/or historical difference values associated with the external system, one or more actions for correcting the anomaly may be selected and performed.

Abstract: Synchronized output of audio on a group of devices can comprise sending audio data from an audio distribution master device to one or more slave devices in the group. Scores can be assigned to respective audio playback devices, the scores being indicative of a performance level of the respective audio playback devices acting as a master device. The device with the highest score is designated as a candidate master device and one or more remaining devices are designated as a candidate slave(s). A throughput test is conducted with the highest scoring device acting as the candidate master device. The results of the throughput test are used to determine a master device for a group of devices. Latency of the throughput test can be reduced by using a prescribed time period for completion of the throughput test, and/or by selecting a first group configuration to passes the throughput test.

Abstract: Techniques for remotely executing a secondary-device driver for generating commands for a secondary device are described herein. For instance, a secondary device (or “appliance”) may reside within an environment, along with a device to which the secondary device communicatively couples. The device may be configured to send control signals to the secondary device for causing the secondary device to perform certain operations. For instance, a user in the environment may provide, to the device, a request that the secondary device perform a certain operation. The device, which may lack some or all of a device driver associated with the secondary device, may then work with a remote service that executes the device driver for the purpose of receiving a command from the device driver and sending the command along to the secondary device. Upon receiving the command, the secondary device may perform the operation.

Abstract: Techniques for causing different devices to perform different operations using a single voice command are described herein. In some instances, a user may define a “scene”, in which a user sets different devices to different states and then associates an utterance with those states or with the operations performed by the devices to reach those states. For instance, a user may dim a light, turn on his television, and turn on his set-top box before sending a request to a local device or to a remote service to associate those settings with a predefined utterance, such as “my movie scene”. Thereafter, the user may cause the light to dim, the television to turn on, and the set-top box to turn on simply by issuing the voice command “execute my movie scene”.

Abstract: Techniques for creating groups of devices for controlling these groups with voice commands are described herein. For instance, an environment may include an array of secondary devices (or “smart appliances”, or simply “devices”) that are configured to perform an array of operations. Users may request to create different groups of these devices, such that the users may control entire groups at a single time with individual voice commands.
