  • Patent number: 11082763
    Abstract: The present invention relates to a communication disruption system. In a first audio path, a microphone receives input sound, an amplifier system amplifies the sound, and a sound system transmits a first output sound. In a second audio path, the microphone receives input sound, a delay circuit delays the sound, the amplifier system amplifies the sound, and the sound system transmits a second output sound. A target speaker will hear the first and second output sounds, with the first output sound being a reproduction of their speech heard nearly simultaneously with the original speech, and the second output sound being a reproduction of their speech heard slightly after the original speech. Due to the delayed auditory feedback effect, the target speaker's concentration will be disrupted, making it difficult for them to continue speaking.

    Abstract: In one example, a video endpoint obtains, from a vertical microphone array, a first audio signal including audio from a target sound source and audio from a horizontally-displaced sound source. The video endpoint obtains, from a horizontal microphone array, a second audio signal and a third audio signal both including the audio from the target sound source and the audio from the horizontally-displaced sound source. Based on the second audio signal and the third audio signal, the video endpoint determines at least one of a first degree of arrival of the audio from the target sound source or a second degree of arrival of the audio from the horizontally-displaced sound source. Based on the at least one of the first degree of arrival or the second degree of arrival, the video endpoint adjusts a gain of the first audio signal.

  • Patent number: 10643609
    Abstract: A speech-processing system can engage in time synchronization between audio capture devices so that if multiple devices detect and process a same utterance, the system may determine which device is closer to a speaker of the utterance by comparing time stamp data from the multiple devices. The devices may synchronize their individual clocks to some time standard that may be disseminated among the devices and/or to a server. When an utterance is captured, the capturing devices may create a time stamp corresponding to when the respective devices detected the utterance. The time stamps may be linked to the synchronized time standard or may be converted to the time standard by another device. The system may then compare the audio data for incoming utterances, and if the same utterance comes from multiple devices, may use the time stamp data to determine which device first detected the utterance.

  • Patent number: 9031257
    Abstract: Method, device and computer program product for processing signals at the device. Signals are received, over a range of angles, at a plurality of sensors of the device, the received signals including an interfering signal received from an interfering source location. An interference delay pattern between receipt of signals at the sensors corresponding to receipt of a signal from the interfering source location is determined. A plurality of regularization signals having a delay pattern matching the determined interference delay pattern are generated. The generated regularization signals are used to determine beamformer coefficients to be applied by a beamformer, and the beamformer applies the determined beamformer coefficients to the signals received by the plurality of sensors, thereby generating a beamformer output.

  • Patent number: 9014394
    Abstract: Systems and methods for retaining a microphone using a microphone boot are disclosed. The microphone boot may include a sound channeling structure for receiving and delivering sound, and a microphone retaining block for retaining a microphone and passing the sound to the microphone. The sound channeling structure may be secured to a housing of an electronic device. The sound channeling structure may include a sound tube and a hooking component that may be insertable into a tunnel and a slot, respectively, of the microphone retaining block. The sound tube may deliver the sound into the tunnel for passing to the microphone. The hooking component may lock into the slot to secure the sound channeling structure to the microphone retaining block. Thus, the microphone boot may be tightly sealed to prevent leakage of the sound, and may fix the microphone within the electronic device even in the presence of external force.

  • Patent number: 9014395
    Abstract: An audio analysis apparatus includes the following components. A main body includes a discrimination unit and a transmission unit. A strap is used for hanging the main body from a user's neck. A first audio acquisition device is provided to the strap or the main body. A second audio acquisition device is provided to the strap at a position where a distance between the second audio acquisition device and the user's mouth is smaller than the distance between the first audio acquisition device and the user's in a state where the strap is worn around the user's neck. The discrimination unit discriminates whether an acquired sound is an uttered voice of the user or of another person by comparing audio signals of the sound acquired by the first and second audio acquisition devices. The transmission unit transmits information including the discrimination result to an external apparatus.

  • Patent number: 9002028
    Abstract: A communication system enhances communications in a noisy environment. Multiple input arrays convert a voiced or unvoiced signal into an analog signal. A converter receives the analog signal and generates digital signals. A digital signal processor determines temporal and spatial information from the digital signals. The processed signals are then converted to audible sound.

  • Patent number: 9002020
    Abstract: Systems and methods for a bone-conduction transducer array configured to provide spatial audio are described, in which the bone-conduction transducer array may be coupled to a head-mountable device so as to provide sound, for example, to a wearer of the head-mountable device. Audio information and a vibration transducer from an array of vibration transducers coupled to the head-mountable computing device may be caused to vibrate based at least in part on the audio signal so as to transmit a sound. Information indicating a movement of the wearable computing device toward a given direction may be received. One or more parameters associated with causing the at least one vibration transducer to emulate the sound from the given direction may then be determined, wherein the one or more parameters are representative of a correlation between the audio information and the information indicating the movement.

  • Patent number: 8989394
    Abstract: Disclosed are an active delay method and an improved wireless binaural hearing device. The binaural hearing device includes: a first hearing device including a first microphone, an amplifier and a wireless transmitter; and a second hearing device including a second microphone, an amplifier, a wireless transmitter, a wireless receiver which receives a signal from the wireless transmitter, an active delay circuit which synchronizes the received signal with a signal acquired by the second microphone, a neural network which synchronizes the delayed signal, and a speaker which converts the synchronized signal into a voice signal. With this configuration, it is possible to prevent incorrect detection of the position of the sound source or paralalia due to a time delay which is produced in the wireless binaural hearing device and reduce noises due to a time difference between both hearing devices, thereby providing a binaural hearing device with high quality.
