Patent number: 11830471Abstract: Disclosed are techniques for performing ray-based acoustic modeling that models scattering of acoustic waves by a surface of a device. The acoustic modeling uses two parameters, a room response representing acoustics and geometry of a room and a device response representing acoustics and geometry of the device. The room response is determined using ray-based acoustic modeling, such as ray tracing. The device response can be measured in an actual environment or simulated and represents an acoustic response of the device to individual acoustic plane waves. The device applies a superposition of the room response and the plane wave scattering from the device response to determine acoustic pressure values and generate microphone audio data. The device can estimate room impulse response (RIR) data using data from the microphones, and can use the RIR data to perform audio processing such as sound equalization, acoustic echo cancellation, audio beamforming, and/or the like.Type: GrantFiled: August 31, 2020Date of Patent: November 28, 2023Assignee: Amazon Technologies, Inc.Inventors: Mohamed Mansour, Wontak Kim, Yuancheng Luo

Patent number: 11762052Abstract: Techniques for improving sound source localization (SSL) are provided. A method for probabilistic SSL using a deep neural network (DNN) may include receiving audio data including a representation of audio such as a wakeword from a microphone array. The audio data may be processed by a DNN to output a plurality of values where each value indicates a probability that the audio originated from a direction corresponding to that value. A sensor may provide computer vision or other data which may be used to inform the plurality of values based on detecting presence of a human or obstacle. A probability that the audio originated from one of the directions of the plurality of directions may be determined based at least in part on the DNN output and the computer vision or other data.Type: GrantFiled: September 15, 2021Date of Patent: September 19, 2023Assignee: Amazon Technologies, Inc.Inventors: Anshuman Ganguly, Mrudula V. Athi, Spencer Russell, Alexander M. Epstein, Wontak Kim

Publication number: 20220182032Abstract: Processes and devices for equalizing an audio system that is adapted to use a loudspeaker to transduce test audio signals into test sounds. The processes and devices can involve the use of infrared signals to convey information in one or both directions between the audio system and a portable computer device that captures test sounds, calculates audio parameters that can be used in the equalization process, and transmits these audio parameters back to the audio system for its use in equalizing audio signals that are played by the audio system.Type: ApplicationFiled: February 22, 2022Publication date: June 9, 2022Applicant: Bose CorporationInventors: Wontak Kim, Michael J. Daley, Laszlo Drimusz, Matthew S. Walsh

Patent number: 11158335Abstract: A voice-controlled device includes a beamformer for determining audio data corresponding to one or more directions and a beam selector for selecting in which direction a source of target audio lies. The device determines magnitude spectrums for each beam and for each frequency bin in each beam for each frame of audio data. The device determines frame-by-frame changes in the magnitude and filters the changes to smooth them. The device selects the beam having the greatest smoothed change in magnitude as corresponding to speech.Type: GrantFiled: March 28, 2019Date of Patent: October 26, 2021Assignee: Amazon Technologies, Inc.Inventors: Anshuman Ganguly, Srivatsan Kandadai, Wontak Kim

Patent number: 11128953Abstract: A system configured to improve spatial coverage of output audio and a corresponding user experience by performing upmixing and loudspeaker beamforming to stereo input signals. The system can perform upmixing to the stereo (e.g., two channel) input signal to extract a center channel and generate three-channel audio data. The system may then perform loudspeaker beamforming to the three-channel audio data to enable two loudspeakers to generate output audio having three distinct beams. The user may interpret the three distinct beams as originating from three separate locations, resulting in the user perceiving a wide virtual sound stage despite the loudspeakers being spaced close together on the device.Type: GrantFiled: August 25, 2020Date of Patent: September 21, 2021Assignee: Amazon Technologies, Inc.Inventors: Yuancheng Luo, Wontak Kim, Mihir Dhananjay Shetye

Patent number: 10986437Abstract: A beamformer system isolates a desired direction of an audio signal received from a first microphone array disposed on a first plane of the system and a second microphone array disposed on a second plane of the system. A spatial covariance matrix (SCM) defines the spatial covariance between pairs of microphones. A diagonal of the SCM is varied based on the placement of the microphones; values corresponding to one microphone array are increased, and values corresponding to the other microphone array are decreased.Type: GrantFiled: June 21, 2018Date of Patent: April 20, 2021Assignee: Amazon Technologies, Inc.Inventors: Guangdong Pan, Chad Jackman, Wontak Kim

Patent number: 10911865Abstract: An omni-directional speaker system includes a deflector sub-assembly and a pair of acoustic sub-assemblies. The deflector sub-assembly includes a pair of diametrically opposed acoustic deflectors. Each of the acoustic sub-assemblies includes an acoustic driver for radiating acoustic energy toward an associated one of the acoustic deflectors. The acoustic sub-assemblies are coupled together via the deflector sub-assembly.Type: GrantFiled: August 26, 2019Date of Patent: February 2, 2021Assignee: BOSE CORPORATIONInventors: Donna Marie Sullivan, Wontak Kim
