  • System and method for applying a convolutional neural network to speech recognition
    Patent number: 9734824
    Abstract: A system and method for applying a convolutional neural network (CNN) to speech recognition. The CNN may provide input to a hidden Markov model and has at least one pair of a convolution layer and a pooling layer. The CNN operates along the frequency axis. The CNN has units that operate upon one or more local frequency bands of an acoustic signal. The CNN mitigates acoustic variation.
    Type: Grant
    Filed: May 25, 2015
    Date of Patent: August 15, 2017
    Assignees: THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTO
    Inventors: Gerald Bradley Penn, Hui Jiang, Ossama Abdelhamid Mohamed Abdelhamid, Abdel-rahman Samir Abdel-rahman Mohamed

  • SYSTEM AND METHOD FOR ACOUSTIC TRANSFORMATION
    Publication number: 20140195227
    Abstract: An acoustic transformation system and method. A specific embodiment is the transformation of acoustic speech signals produced by speakers with speech disabilities in order to make those utterances more intelligible to typical listeners. These modifications include the correction of tempo or rhythm, the adjustment of formant frequencies in sonorants, the removal of adjustment of aberrant voicing, the deletion of phoneme insertion errors, and the replacement of erroneously dropped phonemes. These methods may also be applied to general correction of musical or acoustic sequences.
