The present disclosure presents a communication device configured to removably attach to a mask, and to receive, transmit, and amplify sound and/or speech from a wearer.

The present disclosure presents a communication device configured to removably attach to a mask, and to receive, transmit, and amplify sound and/or speech from a wearer.

A system for determining a location of a device includes at least two speakers and the device, where each speaker is configured to produce a unique sound. The device includes microphones for receiving sound and for providing signals corresponding thereto, a memory configured to store for each speaker a fingerprint of each unique sound and speaker location information, and a processor connected to the outputs. The processor is configured to determine, by comparing microphone signals to fingerprints, a difference in arrival time of a sound at two microphones, and determine, based on the differences in arrival time, an orientation of the device with respect to the speakers, and to determine the location of the device in the space.

A stereo sound pickup method and apparatus, a terminal device, and a computer-readable storage medium. The method includes configuring a terminal device to record a video, wherein the terminal device comprises a plurality of microphones, configuring the plurality of microphones to capture a sound, and forming a stereo beam based on the captured sound. The stereo beam is related to a video recording scenario of the terminal device, and the video recording scenario includes a posture of the terminal device and usage of a camera, the posture includes that the terminal device is in a landscape mode or a portrait mode, and the usage of the camera includes that a rear-facing camera is used or a front-facing camera is used.

Acoustic microphone array systems including arrays of microphones placed on a printed circuit board or other substrate in asymmetric patterns. A plurality of additional non-microphone components also reside on the board. The asymmetric placement of the microphones in the array provides flexibility in physically accommodating the additional non-microphone components.

An audio sample including speech and ambient sounds is transmitted to a vehicle computer. Recorded audio is received from the vehicle computer, the recorded audio including the audio sample broadcast by the vehicle computer and recorded by the vehicle computer and recognized speech from the recorded audio. The recognized speech and text of the speech are input to a machine learning program that outputs whether the recognized speech matches the text. When the output from the machine learning program indicates that the recognized speech does not match the text, the recognized speech and the text are included in a training dataset for the machine learning program.

One embodiment provides a method comprising determining stimuli for simultaneously exciting a plurality of speakers within a spatial area. The method further comprises simultaneously exciting the plurality of speakers by providing the stimuli to the plurality of speakers at the same time for reproduction. The method further comprises recording, during the reproduction, one or more measurements of sound arriving at one or more microphones within the spatial area. The method further comprises simultaneously deconvolving a plurality of impulse responses of the plurality of speakers based on the stimuli and the one or more measurements.
