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: Techniques for synchronizing communication across devices are described. A system receives an input command corresponding to an announcement and sends data representing the announcement to devices of the system. The system receives responses from the devices and causes the device that originated the announcement to output content corresponding to the responses.

Abstract: Techniques for structuring knowledge bases specific to a user or group of users and techniques for using the knowledge bases to answer user inputs are described. A knowledge base may be populated with information provided by users associated with the knowledge base. Users associated with a knowledge base may be proactive in providing content to the knowledge base and/or a system may solicit an answer to a user input from users associated with a particular knowledge base. When the system receives an answer, the system may populate the knowledge base with the answer and may output the answer to the user that originated the user input. The system may output user inputs to be answered using messages or by establishing two-way communication sessions.

Abstract: Techniques for communicating announcements across devices are described. A system performs speech processing on input audio data to determine a command to output an announcement. The system determines devices outputting indicators representing users are proximate thereto. The system generates output audio data corresponding to at least a portion of the input audio data corresponding to announcement content. The system sends the output audio data to the devices along with instructions to output audio corresponding to the output audio data.
