Abstract: A method and intelligent recording and action system (IRAS) for initiating action based on content played by a vehicle infotainment system in a vehicle is described. The method comprises detecting a voice command in an audio signal received by at least one microphone; determining that the voice command relates to audio content output by the vehicle infotainment system and, based on that determination, parsing buffered output audio content from the vehicle infotainment system to extract data relating to the voice command; and initiating an action based on the extracted data and the voice command.

Abstract: A system and method for a vehicular alert that detects a person or animal, determines an environmental noise level from a microphone, determines an alert characteristic response to detection of the person or animal, and emits the alert signal based on the determined alert characteristic, which is adjusted based on the environmental noise level. The alert signal draws the attention of the person or animal to the vehicle to reduce the likelihood of an accident.

Abstract: A digital audio system, which may be an integrated audio system of a vehicle, includes a microphone, a loudspeaker, and a processor. The processor is operable to modify digital audio signals based on tuning parameters to compensate for acoustic characteristics of the environment. The processor is further operable to detect that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment. The detection is based on an audio signal corresponding to audio captured from the environment and/or on the values of the tuning parameters. Upon detecting that modification of digital audio signals based on the tuning parameters cannot fully compensate for the acoustic characteristics of the environment, an indication is provided that the audio system should be calibrated to adjust the tuning parameters to the environment. Related methods and computer-readable media are also disclosed.

The method comprises: determining frequency and amplitude characteristics of the powertrain noise; determining amplitude characteristics of background noise in the vehicle; dynamically generating a masking audio signal based on the determined characteristics of the powertrain noise and background noise; and outputting the masking audio signal in a cabin of the vehicle.

Abstract: A method and system of fault detection for an alert generation system. In the audio alert generation system, a stored digital alert audio file is selected to be processed to generate an analog audio signal to drive a speaker. An alert fault detection system obtaining a signal from the audio alert generation system, converts the obtained signal to a digitally-formatted obtained audio signal, detects a fault in the audio alert generation system by comparing the digitally-formatted obtained audio signal with the stored digital alert audio file, and triggers a fault indicator.

Abstract: A multimodal system and process processed one or more sensor signals and extracts features from the one or more sensor signals through a spatiotemporal correlation between consecutive frames of an image or video sequence. The multimodal system and process determines the movement and direction of the features through an image subtraction, or a coherence measure and synthesizes a musical instrument signal in response to the detected movement and direction or the triggers. The imaginary musical instrument signal is added to an infotainment signal within a vehicle.

Abstract: A system and method for pedestrian alert that derives a pedestrian path representing a projected path for a pedestrian, derives a vehicle path representing a projected path for a motor vehicle, determines an intersection of the pedestrian path and the vehicle path, determines alert characteristics responsive to the determined intersection, and generates an alert that is emitted from the vehicle responsive to the determined alert characteristics. The system and method for pedestrian alert may be built, installed or implemented in a motor vehicles that is operated in environments where the motor vehicle may be in close proximity to pedestrians. The system and method for pedestrian alert mitigates the likelihood of a collision between the motor vehicle and a pedestrian by emitting an alert that may draw the attention of the pedestrian to the presence of the motor vehicle.

Abstract: A system and method for processing an audio signal captured from a microphone may reproduce a known audio signal with an audio transducer into an acoustic space. The known audio signal may include content from one or more audio sources. A microphone audio signal may be captured from the acoustic space where the microphone audio signal comprises the known audio signal and one or more unknown audio signals. Processing control information may be accessed. The known audio signal may be reduced in the microphone audio signal responsive to the processing control information where the processing control information indicates one or more characteristics of a downstream audio processor that processes the microphone audio signal.
