  • Patent number: 11862177
    Abstract: Embodiments described herein provide for systems and methods for implementing a neural network architecture for spoof detection in audio signals. The neural network architecture contains a layers defining embedding extractors that extract embeddings from input audio signals. Spoofprint embeddings are generated for particular system enrollees to detect attempts to spoof the enrollee's voice. Optionally, voiceprint embeddings are generated for the system enrollees to recognize the enrollee's voice. The voiceprints are extracted using features related to the enrollee's voice. The spoofprints are extracted using features related to features of how the enrollee speaks and other artifacts. The spoofprints facilitate detection of efforts to fool voice biometrics using synthesized speech (e.g., deepfakes) that spoof and emulate the enrollee's voice.

  • Patent number: 11677944
    Abstract: Embodiments of the present disclosure include a video compression method, an electronic device, and a computer program product. In a video compression method provided by embodiments of the present disclosure, a video is segmented into multiple segments based on a first feature of an object extracted from the video, where the object has a first change in each of the multiple segments, and the first feature identifies a start state and an end state of the first change; the multiple segments are grouped based on a similarity of the first change of the object among the multiple segments; and the video is compressed based on the groups of the multiple segments. In this way, for a video with periodically repetitive content, the video is compressed by retaining a part of representative video segments, which can save storage space and network transmission resources and improve computation efficiency, thereby reducing computation cost.
