Patent number: 11211062Abstract: Provided are an intelligent voice recognition method, a voice recognition device, and an intelligent computing device. A method of intelligently recognizing a voice in a voice recognition device includes obtaining an ambient noise signal from the microphone detection signal when a voice is detected from the microphone detection signal; updating a previously learned noise cancellation model based on the ambient noise; and removing the ambient noise signal from the microphone detection signal. Therefore, a voice recognition performance of the voice recognition device can be maximized. At least one of the voice recognition device, the intelligent computing device and the server of the present disclosure may be associated with an Artificial Intelligence module, a drone (Unmanned Aerial Vehicle, UAV), robot, Augmented Reality (AR) device, virtual reality (VR) device and a device related to the 5G service.Type: GrantFiled: October 3, 2019Date of Patent: December 28, 2021Assignee: LG ELECTRONICS INC.Inventor: Bongki Lee

Patent number: 11195506Abstract: A sound-modulating window assembly, as well as systems and methods of using and operating the same, are disclosed herein. The sound-modulating window assembly can include sensors, a controller, and a sound modulation assembly. The sound-modulating window assembly The sound-modulating window assembly can receive information about one or more sounds in a vehicular environment. Then, the sound-modulating window assembly can produce a modulation profile. The modulation profile can be used by the sound modulation assembly to alter one or more characteristics of the windows, such that the sounds are mitigated or minimized.Type: GrantFiled: December 3, 2018Date of Patent: December 7, 2021Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventor: Umesh N.

Patent number: 11193783Abstract: In device-assisted navigation, audio navigation cues are often presented at particular locations along a route (e.g., “in 200 meters, turn left” and “turn left here”). However, if the user stops, navigation cues also stop since the user's position is not changing. Additionally, the navigation instruction at the next navigation point may be conflated with the actual position of the next navigation point; e.g., an instruction to “turn left” may be confusing if the road takes a sharp right turn immediately before the next navigation point. Instead, the device may periodically compare the current position of the user and the next navigation point, and periodically present guidance audio cues that indicate the distance and heading offset to the next navigation point. Guidance audio cues may be integrated with and/or supplemented by audio navigation instructions to indicate both the location of the next navigation point and instructions to be followed there.Type: GrantFiled: April 4, 2017Date of Patent: December 7, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Felix Gerard Torquil Ifor Andrew, Geoffrey T.
