Abstract: A speech recognition platform configured to receive an audio signal that includes speech from a user and perform automatic speech recognition (ASR) on the audio signal to identify ASR results. The platform may identify: (i) a domain of a voice command within the speech based on the ASR results and based on context information associated with the speech or the user, and (ii) an intent of the voice command. In response to identifying the intent, the platform may perform a corresponding action, such as streaming audio to the device, setting a reminder for the user, purchasing an item on behalf of the user, making a reservation for the user or launching an application for the user. The speech recognition platform, in combination with the device, may therefore facilitate efficient interactions between the user and a voice-controlled device.

Abstract: Multiple edits to a hierarchical data structure may be atomically applied. A request to perform modifications with respect to a portion or the entire hierarchical data structure may be received. A copy of the requested portion of the hierarchical data structure may be created separate from the hierarchical data structure. The portion of the hierarchical data structure may remain available for read access. Modifications may be applied to the copy of the portion of the hierarchical data structure. In response to a request to commit the modifications to the portion of the hierarchical data structure, the copy of the portion of the hierarchical data structure may atomically replace the portion of the hierarchical data structure.

Abstract: Resource data objects describing resources in a system may be maintained in multiple different hierarchies for applying policies to manage the resources. Lookup requests may access the different hierarchies to determine which policies are applicable to a given resource based on the policies identified in each of the hierarchies. Modifications to hierarchies may be performed in isolation so that the application of policies in other hierarchies is unchanged by modifications to a different hierarchy. Access restrictions may be enforced with respect to hierarchies so that different users may be permitted access to different hierarchies for system resource management.

Abstract: A vehicle driver assist system includes a mounting bracket connectable with the vehicle and a camera housing connectable with the mounting bracket. One of the mounting bracket and the camera housing includes a channel for receiving a tab on the other of the mounting bracket and the camera housing. The tab on the other of the mounting bracket and the camera housing slides into the channel in the one of the mounting bracket and the camera housing to connect the camera housing to the mounting bracket. The one of the mounting bracket and the camera housing has a flexible member that engages the tab to damp movement of the housing relative to the mounting bracket.

Abstract: Described are systems, methods, and apparatus that enable constraint based communications between two or more devices. For example, a first user of a first device may submit a communication request to establish a communication session with a second user and provide a constraint for that communication session, such as a time-limit (e.g., limit the communication session to five minutes). In such an example, if the second user accepts the communication request with the constraint, a communication session is established and the system monitors the communication session to determine when a condition corresponding to the constraint has been satisfied. When the condition is satisfied, the communication session is terminated by the system.

Abstract: Methods and systems for facilitating communications between shared electronic devices are described herein. In some embodiments, a group account may be assigned to a shared electronic device. The group account may include one or more user accounts, where individuals associated with those user accounts may interact with the shared electronic device, and also may form a part of the group account. When a message is sent from one shared electronic device to another personal device or shared electronic device, the message may be indicated as being sent from the group account, as if the shared electronic device corresponds to its own separate account. In some embodiments, speaker identification processing may be employed to determine a speaker of the message and, if the speaker is able to be identified, the message may be sent from the corresponding speaker's user account instead of the shared electronic device's corresponding group account.

Abstract: A system that is capable of controlling multiple entertainment systems and/or speakers using voice commands. The system receives voice commands and may determine audio sources and speakers indicated by the voice commands. The system may generate audio data from the audio sources and may send the audio data to the speakers using multiple interfaces. For example, the system may send the audio data directly to the speakers using a network address, may send the audio data to the speakers via a voice-enabled device or may send the audio data to the speakers via a speaker controller. The system may generate output zones including multiple speakers and may associate input devices with speakers within the output zones. For example, the system may receive a voice command from an input device in an output zone and may reduce output audio generated by speakers in the output zone.

Abstract: Systems and methods for sender profile and/or recipient profile disambiguation and/or confirmation are disclosed. In instances where a sender profile is not indicated by a user sending a communication from a communal device, heuristic data may be utilized to infer the sender profile. Similar heuristic data may also be used when selection of the sender profile is associated with a low confidence level. Heuristic data may also be used to infer the recipient profile when the user does not indicate the recipient profile or when selection of the recipient profile is associated with a low confidence. Various confirmations may result from the sender and recipient profile disambiguation.

Abstract: Methods and systems for providing message playback using a shared electronic device is described herein. In response to receiving a request to output messages, a speech-processing system may determine a group account associated with a requesting device, and may determine messages stored by a message data store for the group account. Speaker identification processing may also be performed to determine a speaker of the request. A user account associated with the speaker, and messages stored for the user account, may be determined. A summary response indicating the user account's messages and the group account's message may then be generated such that the user account messages are identified prior to the group account's messages. The messages may then be analyzed to determine an appropriate voice user interface for the requester such that the playback of the messages using a shared electronic device is more natural and conversational.

Abstract: An interactive system may be implemented in part by an audio device located within a user environment, which may accept speech commands from a user and may also interact with the user by means of generated speech. In order to improve performance of the interactive system, a user may use a separate device, such as a personal computer or mobile device, to access a graphical user interface that lists details of historical speech interactions. The graphical user interface may be configured to allow the user to provide feedback and/or corrections regarding the details of specific interactions.
