  • Publication number: 20250054479
    Abstract: An audio device is disclosed, comprising multiple microphones and an audio module. The multiple microphones generate multiple audio signals. The audio module coupled to the multiple microphones comprises a processor, a storage media and a post-processing circuit. The storage media includes instructions operable to be executed by the processor to perform operations comprising: producing multiple instantaneous relative transfer functions (IRTFs) using a known adaptive algorithm according to multiple spectral representations for multiple first sample values in current frames of the multiple audio signals; and, performing distractor suppression over the multiple spectral representations and the multiple IRTFs using an end-to-end neural network to generate a compensation mask. The post-processing circuit generates an audio output signal according to the compensation mask.

  • Patent number: 7496497
    Abstract: A method and system provide for selecting a web site home page in a desired language. The method comprises identifying within a web address request a directional information item by extracting from the request a site language cookie stored in a user's access device, providing a web page associated with the web address to a second web site corresponding to the directional information item wherein the second web site includes a language translator, translating the web page textual information in accordance with the language translator and returning the translated web page to the user. The method further provides for accessing a control table to determine a status of the web page and obtaining a version of the web page stored locally on the second site or otherwise obtaining a current version of the web page; and translating the obtained web page.
