  • Publication number: 20230395068
    Abstract: The present invention provides a noise modeling method to improve the speech recognition quality to help the recognition system perform better in real-life environments. With this method, we not only add noise to the training audio signal to simulate different environments, but we also add noise labels to the speech transcripts. Since then, the recognition model will perform better in different environments and increase the accuracy of the recognition model.

  • Publication number: 20150314136
    Abstract: A photo-medicine device may include a housing having: a mounting member and an application member including an aperture. An LED array having at least one LED configured to emit light through the aperture at a first wavelength and at least one LED configured to emit light through the aperture at a second wavelength may be mounted to the mounting member. The LED array may be in thermal communication with the mounting member such that the housing functions as a heat sink for the LED array. In some embodiments, the first wavelength comprises approximately 415 nm and the second wavelength comprises approximately 660 nm. In some embodiments, the housing has a heat dissipation surface area of at least three square inches per LED watt.
