Patents by Inventor Jan DeMoortel

Jan DeMoortel 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).

  • Corpus-based prosody translation system
    Patent number: 7069216
    Abstract: A method of prosody translation is given. A target input symbol sequence is provided, including a first set of speech prosody descriptors. An instance-based learning algorithm is applied to a corpus of speech unit descriptors to select an output symbol sequence representative of the target input symbol sequence and including a second set of speech prosody descriptors. The second set differs from the first set.
    Type: Grant
    Filed: October 1, 2001
    Date of Patent: June 27, 2006
    Assignee: Nuance Communications, Inc.

  • Speech synthesis using concatenation of speech waveforms
    Publication number: 20040111266
    Abstract: A high quality speech synthesizer in various embodiments concatenates speech waveforms referenced by a large speech database. Speech quality is further improved by speech unit selection and concatenation smoothing.
    Type: Application

  • Time scale modification of digitally sampled waveforms in the time domain
    Publication number: 20020133334
    Abstract: A system is disclosed for generating a time scale modification of a digital waveform. A digital waveform provider produces an input digital waveform at a first time resolution, the digital waveform being a sequence of overlapping speech segment windows. A time-domain time scale modification process overlap adds selected windows from the input digital waveform to create an output digital waveform representing a time scale modification of the input digital waveform. The process operates at a second time resolution lower than the first time resolution to determine the relative positions between adjacent windows in the output digital waveform.
