Patent number: 12327550Abstract: Systems and methods for intelligent device grouping are disclosed. An environment, such as a home, may have a number of voice-enabled devices and accessory devices that may be controlled by the voice-enabled devices. One or more models, such as linguistics model(s) and/or device affinity models may be utilized to determine which accessory devices are candidates for inclusion in a device group, and a recommendation for grouping the devices may be provided. Device-group naming recommendations may also be generated and may be sent to users.Type: GrantFiled: June 23, 2022Date of Patent: June 10, 2025Assignee: Amazon Technologies, Inc.Inventors: Zeya Chen, Charles Edwin Ashton Brett, Jay Patel, Lizhen Peng, Aniruddha Basak, Hongyang Wang, Yunfeng Jiang, Sven Eberhardt, Akshay Kumar, William Evan Welbourne, Sara Hillenmeyer

Patent number: 12236957Abstract: Systems and methods for presence ground truth approximation and utilization are disclosed. For example, a system detects the presence of a predefined subject, such as a person associated with a given user profile, and/or determines that authentication criteria for performing an action in association with the user profile has been satisfied. A period of time to associate data is determined, and data of one or more data types is labeled as being associated with the speaker identification event. That data may be formatted and input into one or more models to train those models to more accurately detect presence and/or determine whether authentication of a user profile should succeed.Type: GrantFiled: September 1, 2022Date of Patent: February 25, 2025Assignee: Amazon Technologies, Inc.Inventors: Lizhen Peng, Alok Upadhyay, Jason Cline, Ankur Gandhe

Patent number: 12033622Abstract: Systems and methods for target-device resolution are disclosed. A user may speak a user utterance requesting an action to be performed with respect to an accessory device, such as a smart-home device. The user utterance may include an identifier for the accessory device, but that identifier may not correspond to a naming indicator of an accessory device and/or may correspond to multiple naming indicators. In these examples, one or more models are utilized to identify which accessory device is most likely to correspond to the accessory device targeted by the user utterance for operation.Type: GrantFiled: February 1, 2021Date of Patent: July 9, 2024Assignee: Amazon Technologies, Inc.Inventors: Lizhen Peng, Sven Eberhardt, Akshay Kumar, Charles Edwin Ashton Brett, Sara Parker Hillenmeyer, William Evan Welbourne

Patent number: 11870862Abstract: Systems and methods for state prediction of devices are disclosed. A group of reference devices may be identified and a subset of the reference devices may be identified and/or determined based at least in part on a degree of similarity between reference usage-patterns associated with the reference devices and a usage pattern of a target device. The current state of the subset of the reference devices may be determined and may be utilized to determine a probability that the target device should be in a given state. The state prediction information may be utilized for one or more actions, such as sending recommendations, target inference operations, and/or device configuration, for example.Type: GrantFiled: September 17, 2018Date of Patent: January 9, 2024Assignee: Amazon Technologies, Inc.Inventors: Charles Edwin Ashton Brett, Sara Parker Hillenmeyer, Sven Eberhardt, William Evan Welbourne, Aniruddha Basak, Lizhen Peng

Patent number: 11067718Abstract: Described are systems, methods, and apparatus that gathers environment condition data from different sensors at various locations within an area, aggregates the environment condition data to produce aggregated environment condition scores for the area and provides the aggregated environment condition scores to different locations within the area. While sensor data from a single sensor/device, such as a camera may provide low quality environment information, by collecting and aggregating information from multiple sensors and/or locations in the area, highly accurate aggregated environment condition scores for environment conditions may be realized. The aggregated environment condition scores may be provided to various locations within the area as representative of the environment condition at that point in time within the area, regardless of whether those locations have sensors.Type: GrantFiled: June 14, 2018Date of Patent: July 20, 2021Assignee: Amazon Technologies, Inc.Inventors: Charles Edwin Ashton Brett, Aniruddha Basak, Zeya Chen, Sara Parker Hillenmeyer, Lizhen Peng, Yunfeng Jiang, William Evan Welbourne, Jay Patel, Sven Eberhardt
