  • Patent number: 11856024
    Abstract: In an approach for prohibiting voice attacks, a processor, in response to receiving a voice input from a source, determines, using a predetermined filter including an allowlist, that the voice input does not match any corresponding entry of the predetermined filter. A processor routes the voice input to an adversarial pipeline for processing. A processor identifies an adversarial example of the voice input using a predetermined connectionist temporal classification method. A processor generates a configurable distorted adversarial example using the adversarial example identified. In response to a user reply, a processor injects the configurable distorted adversarial example as noise into a voice stream of the user reply in real-time to alter the voice stream. A processor routes the altered voice stream to the source.
    Type: Grant

  • Patent number: 10419617
    Abstract: Embodiments of the disclosure relate to interactive voicemail tagging of messages and responses to provide improved navigation and tracking of information requested/contained in voicemail messages and responses. Users may tag portions of the recorded message/response to indicate presence of a request for information, an answer providing requested information, etc. and navigate to particular portions of the recorded message/response using the tags. Accordingly, in one embodiment a computer-implemented method for interactive voicemail message and response tagging and processing includes: receiving a prompt having associated therewith one or more prompt tags; receiving a response corresponding to the prompt, the response having associated therewith one or more response tags; and processing the response to determine either or both of a content of the response and a context of the response. Corresponding systems and computer program products are also disclosed.
