  • Patent number: 11348595
    Abstract: A system and method that enhances spoken utterances and provides entertainment by capturing one or more microphone signals containing echo and decomposing the one or more microphone signals into a plurality of signal paths through a synthesizer that adds or makes non-linear modifications to some of the captured one or more microphone signals. The system and method and estimates multiple echo paths from each of the one the one or more microphones. The system and method processes the captured microphone signals in response to the estimated plurality of echo paths by subtracting the echo contributions of each of the plurality of echo paths from the captured one or more microphone signals. The system and method also provide signal separation and post processing functions that renders speech recognition gaming applications.

  • Publication number: 20210096813
    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.

  • Patent number: 10793066
    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.

  • Patent number: 10638226
    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.

  • Patent number: 10580288
    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.

  • Patent number: 10497346
    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.
