Keng Hoong Wee has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Generating speech and voice from extracted signal attributes using a speech-locked loop (SLL)
    Patent number: 8688438
    Abstract: A speech processing system includes a plurality of signal analyzers that extract salient signal attributes of an input voice signal. A difference module computes the differences in the salient signal attributes. One or more control modules control a plurality of speech generators using an output signal from the difference module in a speech-locked loop (SLL), the speech generators use the output signal to generate a voice signal.
    Type: Grant
    Filed: February 9, 2010
    Date of Patent: April 1, 2014
    Assignee: Massachusetts Institute of Technology
    Inventors: Keng Hoong Wee, Lorenzo Turicchia, Rahul Sarpeshkar
