Title: Andre Gillet: Innovator in Speech Recognition Technology
Introduction
Andre Gillet is a notable inventor based in St-Laurent, Canada. He has made significant contributions to the field of speech recognition technology. With a total of 2 patents, his work has advanced the capabilities of speech recognition systems.
Latest Patents
Gillet's latest patents include a "Search and rescoring method for a speech recognition system." This invention processes input speech signals organized into a series of frames. The system decimates the input speech signal to select K frames out of every L frames according to a decimation rate K/L. A first set of model distances is calculated for each of the K selected frames, and a Hidden Markov Model (HMM) topology is reduced based on the decimation rate. The system then selects a reduced set of model distances and a first plurality of candidate choices for recognition. A second set of model distances is computed for a second plurality of candidate choices, which correspond to a subset of the first plurality. The second plurality is rescored, and a recognition result is selected accordingly.
Another patent is titled "Method and apparatus for speech recognition." This invention compares a series of observations representing unknown speech to stored models of known speech. The observations are divided into blocks, and the comparison is carried out in an order that optimizes memory usage. The process involves determining the likelihood of a match for each model and is repeated for each block.
