Patent number: 11950062Abstract: A system configured to improve sound source localization (SSL) processing by reducing a number of direction vectors and grouping the direction vectors into direction cells is provided. The system performs clustering to generate a smaller set of direction vectors included in a delay-direction codebook, reducing a size of the codebook to the number of unique delay vectors. In addition, the system groups the direction vectors into direction cells having a regular structure (e.g., predetermined uniformity and/or symmetry), which simplifies SSL processing and results in a substantial reduction in computational cost. The system may also select between multiple codebooks and/or dynamically adjust the codebook to compensate for changes to the microphone array. For example, a device with a microphone array fixed to a display that can tilt may adjust the codebook based on a tilt angle of the display to improve accuracy.Type: GrantFiled: March 31, 2022Date of Patent: April 2, 2024Assignee: Amazon Technologies, Inc.Inventors: Wai Chung Chu, Carlo Murgia

Patent number: 11636842Abstract: An ear-mountable listening device includes an array of microphones physically arranged into a ring pattern to capture sounds from an environment and output first audio signals that are representative of the sounds captured by the microphones. A speaker is arranged to emit audio into an ear in response to a second audio signal. Electronics are coupled to the array of microphones and the speaker and configured to capture the sounds with the array of microphones to generate the first audio signals and generate the second audio signal that drives the speaker based upon one or more of the first audio signals.Type: GrantFiled: January 29, 2021Date of Patent: April 25, 2023Assignee: Iyo Inc.Inventors: Simon Carlile, Jason Rugolo

Patent number: 11632635Abstract: A hearing aid comprises a) a multitude of M input transducers each providing an electric input signal representative of environment sound in a time-frequency representation (k, l), and each comprise varying amounts of target (s) and noise (v) signal components; b) a signal processor configured to process said multitude of electric input signals; and comprising a beamformer filter configured to receive said multitude M of electric input signals and to provide a spatially filtered signal and a post-filter configured to receive said spatially filtered signal and to provide an estimate ?(k,l) of a target signal representing said target signal components from said target sound source. The signal processor is configured to provide estimates of power spectral densities ?s(k,l) of said target signal components in dependence of inter-frequency bin relationships between the spectral components enforced by properties of the electric input signals across at least some of said frequency bins.Type: GrantFiled: April 16, 2021Date of Patent: April 18, 2023Assignee: Oticon A/SInventors: Adel Zahedi, Michael Syskind Pedersen, Lars Bramsløw, Thomas Ulrich Christiansen, Jesper Jensen

Patent number: 11626095Abstract: An acoustic noise reduction (ANR) headphone described herein has current detection circuitry that detects current consumed by an acoustic driver amplifier as a result of pressure changes due to a tapping of the headphone. Tapping may be performed to change an audio feature or operating mode of the audio system for the headphone. The current detection circuitry senses a characteristic of the current consumed by the acoustic driver amplifier that can be used to determine an occurrence of a tap event. Examples of a characteristic include an amplitude, waveform or duration of the sensed current. Advantageously, the ANR headphones avoid the need for control buttons to initiate the desired changes to the audio feature or operating mode.Type: GrantFiled: May 3, 2021Date of Patent: April 11, 2023Assignee: Bose CorporationInventor: Paul G.

Patent number: 11606659Abstract: Techniques for adaptive cross-correlation are discussed. A first signal is received from a first audio sensor associated with a vehicle and a second signal is received from a second audio sensor associated with the vehicle. Techniques may include determining, based at least in part on the first signal, a first transformed signal in a frequency domain. Additionally, the techniques include determining, based at least in part on the second signal, a second transformed signal in the frequency domain. A parameter can be determined based at least in part on a characteristic associated with at least one of the vehicle, an environment proximate the vehicle, or one or more of the first or second signal. Cross-correlation data can be determined based at least in part on one or more of the first transformed signal, the second transformed signal, or the parameter.Type: GrantFiled: March 29, 2021Date of Patent: March 14, 2023Assignee: Zoox, Inc.Inventors: Venkata Subrahmanyam Chandra Sekhar Chebiyyam, Turhan Karadeniz, Nam Gook Cho, Subasingha Shaminda Subasingha

Patent number: 11606408Abstract: A method is provided for synchronizing a source device with a sink device. The source device transmits a stream of packets to the sink device. The source device receives feedback from the sink device indicating packet arrival times of the packets at the sink device. Based on the feedback, in some aspects, the source device determines an average time shift in the packet arrival times at the sink device, wherein the average time shift is relative to expected packet arrival times of the packets at the sink device. In some such aspects, the source device detects that the average time shift exceeds a threshold, and in response to the detecting, adjusts a streaming time of the stream of packets to synchronize, within a predefined tolerance, the source device with the sink device.Type: GrantFiled: July 6, 2021Date of Patent: March 14, 2023Assignee: Bose CorporationInventors: Pankaj Aggarwal, Michael Elliot, Mark Corey Hatch, Dmitrij Golubovskij

Patent number: 11605393Abstract: An audio cancellation system includes a voice enabled computing system that is connected to an audio output device using a wired or wireless communication network. The voice enabled computing device can provide media content to a user and receive a voice command from the user. The connection between the voice enabled computing system and the audio output device introduces a time delay between the media content being generated at the voice enabled computing device and the media content being reproduced at the audio output device. The system operates to determine a calibration value adapted for the voice enabled computing system and the audio output device. The system uses the calibration value to filter the user's voice command from a recording of ambient sound including the media content, without requiring significant use of memory and computing resources.Type: GrantFiled: January 26, 2021Date of Patent: March 14, 2023Assignee: Spotify ABInventors: Richard Mitic, Robert Swain, Daniel Bromand, Waqar Sheikh, James Robert Stansfield

Patent number: 11587577Abstract: A method and apparatus for mobile emulator determination using sound fingerprinting is disclosed. The method includes a verification computer system receiving a transaction request from a computing device purporting to be a mobile device. Responsive to receiving the request, the verification computer system transmits a request for verification information to the computing device. The verification system includes information regarding a tone to be generated by a speaker of the computing device. Thereafter, verification information is received from the computing device. The verification information includes information tone information generated by the computing device, wherein the tone is, after generation, detected by a microphone. The verification system then verifies, based on the receive verification information, whether the information indicates that the computing device is a mobile device.Type: GrantFiled: May 18, 2021Date of Patent: February 21, 2023Assignee: PayPal, Inc.Inventors: Yotam Perkal, Yuri Shafet
