Abstract: Techniques for disambiguating which profile, of multiple profiles, is to be used to respond to a user input are described. A device located in a communal space (e.g., a hotel room or suite of rooms, conference room, hospital room, etc.) may be associated with a device profile and a user profile of a user presently occupying the communal space. When the user inputs a command to the device (either by text or speech), a system associated with the device determines the profiles (e.g., a device profile and a user profile) associated with the device. The system determines one or more policies associated with the device. The one or more policies may correspond to rules for disambiguating which profile to use to execute with respect to the user input. Using the one or more policies, the system determines which profile is to be used, and causes a speechlet component to execute using information specific to the determined profile.

Abstract: Techniques for implementing a “sticky” user ID are described. A system receives first input audio data and determines first speech processing results therefrom. The system also determines a first user ID of a user that spoke an utterance represented in the first input audio data and associates the first user ID with a device, which originated the first input audio data, for a predetermined length of time. The system determines first output data responsive to the first speech processing data and causes the device to present first output content corresponding thereto. The system then receives second input audio data and determines second speech processing results therefrom. The system also determines a time of receipt of the second input audio data is within the predetermined length of time. Based at least in part thereon, the system determined second output data responsive to the second speech processing data using the first user ID.
