Title: Filip Van Aelten: Innovator in Speech Recognition Technology

Introduction

Filip Van Aelten is a notable inventor based in Merelbeke, Belgium. He has made significant contributions to the field of speech recognition technology, holding 2 patents that showcase his innovative approach to automatic speech recognition systems.

Latest Patents

One of his latest patents is titled "Compound words in speech recognition systems." This invention involves an automatic speech recognition system that includes a recognition engine, a compound lexicon, and a compounder. The recognition engine generates a recognition result that consists of a sequence of recognized words representative of an input utterance. The words in the recognition result include compound word components that can be combined to form compound words. The engine utilizes a recognition vocabulary and a language model that associates the likelihood of specific words occurring at given positions in the sequence. The compound lexicon contains various compound word components and connecting links structured to facilitate the combination of components that are likely to occur together. The compounder replaces adjacent words in the recognized sequence with a concatenation of the corresponding linked components, minimizing the likelihood of a component occurring without a corresponding linked component for concatenation.

Another significant patent is the "Search algorithm for large vocabulary speech recognition." This invention generates automatic speech recognition word sequence hypotheses using an interleaved forward-backward search. The forward search pass employs relatively simple models for a specific block period, while the backward search pass revisits the previous block period using more complex models and the hypotheses generated by the forward search. This backward search pass utilizes a word-dependent n-best search with a flat model state organization.
