  • Publication number: 20250046333
    Abstract: In general, the disclosure describes a computing system to automatically identify and classify audio input, including non-speech audio signals. The computing system may also add new classes based on only a limited number of examples of the new classes, to identify classes of sounds for which the system had not been trained.

  • Publication number: 20250029601
    Abstract: In general, the disclosure describes techniques for detecting synthetic speech of a speaker. In an example, a machine learning system may be configured to generate, using a deep learning model trained to distinguish between synthetic speech and authentic speech, reference embeddings for the speaker that characterize a first set of acoustic features and a first set of phonetic features associated with the speaker. The machine learning system may further be configured to generate, using the deep learning model, a test embedding for an audio clip that characterizes a second set of acoustic features and a second set of phonetic features associated with the audio clip. The machine learning system may further be configured to compute a score based on the test embedding and the reference embeddings. The machine learning system may further be configured to output, based on the score, an indication of whether the audio clip includes synthetic speech.

  • Publication number: 20240379112
    Abstract: In general, the disclosure describes techniques for detecting synthetic speech in an audio clip. In an example, a computing system may include processing circuitry and memory for executing a machine learning system. The machine learning system may be configured to process an audio clip to generate a plurality of speech artifact embeddings based on a plurality of synthetic speech artifact features. The machine learning system may further be configured to compute one or more scores based on the plurality of speech artifact embeddings. The machine learning system may further be configured to determine, based on the one or more scores, whether one or more frames of the audio clip include synthetic speech. The machine learning system may further be configured to output an indication of whether the one or more frames of the audio clip include synthetic speech.

  • Patent number: 11999411
    Abstract: A vehicle is disclosed that includes: a grille supporting a functional accessory; a bumper beam that is located (positioned) axially inward of the grille; and a first energy absorber that is connected to the bumper beam. The first energy absorber defines a cavity that is configured to accommodate inward axial displacement of the grille resulting from a low-force impact between the vehicle and an external object to thereby inhibit damage to the functional accessory.

  • Patent number: 11511691
    Abstract: A vehicle includes: a bumper assembly defining opposite lateral ends and an overall width extending therebetween, the bumper assembly defining a recessed area located between the opposite lateral ends thereof; an electronic sensor supported by the bumper assembly in cantilevered relation; and an energy absorber positioned within the recessed area to protect the electronic sensor and reduce dislocation of the electronic sensor by absorbing energy resulting from an impact between the vehicle and an external object. The energy absorber defines opposite lateral ends and an overall width extending therebetween less than that the overall width of the bumper assembly such that the opposite lateral ends of the energy absorber are spaced inwardly from the opposite lateral ends of the bumper assembly.

  • Patent number: 10850697
    Abstract: A vehicle includes: a bumper beam; an electronic sensor that is fixed in relation to the bumper beam; and an energy absorber that is connected to the bumper beam in general alignment with the electronic sensor. The energy absorber is configured and positioned to protect the electronic sensor and reduce dislocation of the electronic sensor by absorbing energy resulting from a low-force impact between the vehicle and an external object (e.g., another vehicle). The energy absorber may be provided in the front and/or rear-ends of the vehicle, and, in certain embodiments, may be connected to an end face of the bumper beam (e.g., to a front face or a rear face of the bumper beam) such that the energy absorber is positioned outwardly (e.g., forwardly or rearwardly) of the electronic sensor along a length of the vehicle.

  • Publication number: 20050075930
    Abstract: Methods and systems for allocating rewards and mapping activity within organizations. Rewards are allocated throughout an organization using a consensus driven model and peer review. In one embodiment employees enter into a system “scores” for fellow employees based on at least one set of criteria. Once the scores are entered the system processes them according to an algorithm in accordance with the present invention and generates an output. In one embodiment the output is generated in the form of a report for management. Amps can be generated to assist in analysis of value within an organization.
