This voice processing device is provided with: an utterer's position detection unit which specifies, as position microphones of an utterer, microphones that receive a voice signal of WuW on the basis of the characteristics of each voice signal for a prescribed time, when the WuW voice is detected, the voice signal being held in a voice signal buffer unit; and a CTC unit (one example of a voice processing unit) which outputs a voice uttered by the utterer and suppress a voice uttered by an occupant, who is not the utterer, by using the voice signal for the prescribed time, which is held in the voice signal buffer unit, and information relating to the utterer's position microphones.

A system for capturing a user's voice, including a plurality of microphones disposed about a vehicle cabin, each of the plurality of microphones generating a microphone signal, wherein the vehicle cabin defines a plurality of seating positions; a voice-activity detector configured to detect when, at least, a user seated in a target seat of the plurality of seating positions is speaking; and an adaptive beamformer configured to receive the microphone signals from the plurality of microphones and to generate, based on the microphone signals and a noise coherence matrix, an estimate of the acoustic signal at the target seating position, according to an adaptive beamforming algorithm, wherein the noise coherence matrix ceases to be updated when, according to the voice-activity detector, the user seated in the target seating position is speaking.

The present application discloses exemplary arrangements of an end-fire microphone array inside a vehicle and exemplary digital signal processors configured for the end-fire in-car microphone array. The exemplary digital signal processors may be configured in two modes, a phone call mode and an automatic speech recognition mode. In each mode, the exemplary digital signal processors are improved for enhanced SNR. Different end-fire microphone array arrangements are also disclosed.

Systems and methods for mitigating wind throb in vehicles are disclosed herein. An example method includes detecting wind throb in a cabin of a vehicle due to opening of a first window of the vehicle, determining when a seat that is adjacent to a second window of the vehicle is unoccupied, opening the second window when the seat is determined to be unoccupied so as to compensate for the wind throb, determining that the first window has been closed, and closing the second window in response to closing of the first window.

A system for capturing a user's voice, including a plurality of microphones disposed about a vehicle cabin, each of the plurality of microphones generating a microphone signal, wherein the vehicle cabin defines a plurality of seating positions; a voice-activity detector configured to detect when, at least, a user seated in a target seat of the plurality of seating positions is speaking; and an adaptive beamformer configured to receive the microphone signals from the plurality of microphones and to generate, based on the microphone signals and a noise coherence matrix, an estimate of the acoustic signal at the target seating position, according to an adaptive beamforming algorithm, wherein the noise coherence matrix ceases to be updated when, according to the voice-activity detector, the user seated in the target seating position is speaking.

A roof module for connection to a motor vehicle having a transparent solid roof portion, which forms a see-through roof area and which is immobile relative to the vehicle body when the roof module is in the installed position, and/or a roof opening system having a mobile lid element, by means of which a roof opening can be opened or closed at will, and a closed roof skin, which forms the see-through roof area and/or is adjacent to the roof opening and forms a roof cover outside of the see-through roof area and/or the roof opening. At least one sensor module can be provided having at least one environment sensor for detecting a vehicle environment and is disposed outside of the see-through roof area and/or the roof opening and is covered by the roof skin.

A vehicle occupant detection system includes a housing. A microprocessor is mounted in the housing and is programmed to detect an engine engagement status of a vehicle. A camera is mounted on the housing and is directed forward of the housing. The camera electrically coupled to the microprocessor is programmed with facial recognition software to compare facial images against images captured by the camera. A motion sensor mounted on the housing detects motion forward of the housing. The camera captures an image when the motion sensor detects motion. A first condition is defined when the motion sensor detects motion, the camera captures an image prompting a facial recognition match and the microprocessor detects the vehicle is parked. A sound emitter is mounted on the housing and is electrically coupled to the microprocessor and emit a low decibel sound when the first condition is first attained.

A method and a device for processing an audio signal in a vehicle are provided. The method includes: obtaining an audio signal by a microphone array; performing echo cancellation on the obtained audio signal, to obtain a first processed signal; and performing beamforming on the first processed signal according to sound zones in which microphones of the microphone array are located, to obtain a second processed signal, wherein the vehicle includes at least two sound zones, and each microphone of the microphone array is located in at least one sound zone. With the beamforming, the requirements for isolation degree between different sound zones is not high, and the sound source of the audio signal can be accurately determined.

The present disclosure relates to a motor vehicle external microphone having at least one microphone unit which has a microphone capsule arranged in a microphone housing, wherein the microphone housing has at least one microphone opening, through which an acoustic channel is formed between the at least one microphone opening and the microphone capsule, wherein the motor vehicle external microphone comprises a changeover device, which is designed to open the at least one microphone opening in an activated state of the motor vehicle external microphone and to close the same in a deactivated state of the motor vehicle exterior microphone. The invention also relates to a motor vehicle roof antenna and to a motor vehicle having such a motor vehicle external microphone. Finally, the invention relates to a method for operating such a motor vehicle external microphone.

A microphone-loudspeaker integrated apparatus includes a plurality of microphones, a loudspeaker, and a synthesis unit. The loudspeaker is disposed between the plurality of microphones. The synthesis unit synthesizes sounds collected from the plurality of microphones. A distance between the plurality of microphones is set so as to fall within a range within which sound at a frequency needed for recognizing voice is collectable and within a range within which a noise amount due to vibration of the loudspeaker is allowable, when voice recognition is performed based on sound obtained through synthesis by the synthesis unit.
