  • Patent number: 9479885
    Abstract: Configuring an adaptive microphone array to gather signals from a main lobe of the array, and configuring the array to reduce side interference gathered from sources that are not situated within the main lobe. A memory stores test signals gathered by the array at a plurality of predetermined angular bearings with reference to the array in an anechoic chamber. Signals gathered in real time are processed to provide a preliminary output and preliminary weights. The test signals are retrieved from memory. The preliminary weights are applied to the test signals to provide null steering weights. The null steering weights and the preliminary output are processed to reduce or minimize the amplitude response of the array at the angular orientation.

  • Patent number: 9462379
    Abstract: A method for controlling the orientation of a virtual microphone, which is carried out on an electronic device, includes combining and processing signals from a microphone array to create a virtual microphone; receiving data from a sensor of the electronic device; determining, based on the received data, a mode in which the electronic device is being used; and based on the determined mode, directionally orienting the virtual microphone. Possible use modes include a) a stowed use mode, in which the criterion is the electronic device being substantially enclosed by surrounding material; b) a handset (alternately, private) use mode, in which the criterion is the electronic device being held proximate to a user; and c) a handheld (alternately, speakerphone) use mode, in which the criterion is the electronic device being held away from a user.

  • Patent number: 9351091
    Abstract: An apparatus includes a group of microphones and a surface compensator that is operatively coupled to switch logic and to a signal conditioner that provides a control channel to voice recognition logic. The surface compensator may detect surfaces in proximity to the apparatus as well as the surface's acoustic reflectivity or acoustic absorptivity and may accordingly configure the group of microphones including selecting appropriate signal conditioning and beamforming based on the surface acoustic reflectivity or acoustic absorptivity and the orientation of the apparatus. Voice recognition performance is thus improved when microphones are impeded or occluded by proximate surfaces. A group of sensors of the apparatus is used by the surface compensator to detect surfaces and surface type, and to determine apparatus orientation and motion.

  • Publication number: 20150172816
    Abstract: A method and apparatus for detecting microphone interference includes first and second built-in microphones producing first and second microphone signals. A first filter bank creates first high-frequency-band and first low frequency-band signals from the first microphone signal. A second filter bank creates second high-frequency-band and second low-frequency-hand signals from the second microphone signal. A first measurement calculator determines a high-frequency-band energy value from the first high-frequency-band signal and the second high-frequency-hand signal when the first and second high-frequency-band signals' magnitudes exceeds predetermined thresholds. A second measurement calculator calculates a low-frequency-band energy value from the first low-frequency-band signal and the second low-frequency-band signal when the first and second low-frequency-band signals' magnitudes exceed predetermined thresholds.

  • Publication number: 20140350926
    Abstract: A method of operation beamforms a plurality of microphone outputs to obtain a plurality of virtual microphone audio channels with at least one audio output channel and at least one audio control channel. The method performs voice recognition on the audio control channel to detect voice commands for controlling audio output channel attributes, and adjusts an audio channel attribute in response to detecting a voice command. Adjusting an attribute of the audio channel may be accomplished by, for example, controlling one or more parameters of an adjustable beamformer. The detected voice commands for controlling audio channel attributes may include voice commands for controlling audio sensitivity zooming, panning in a specified direction, focusing on a specified direction, blocking a specified direction, mixing a narrator's voice, blocking a narrator's voice, or reducing background noise. An apparatus that performs the method of operation is also disclosed.
