Title: Kazuhiro Kondo: Innovator in Phonetic Modeling and Speech Recognition
Introduction
Kazuhiro Kondo is a notable inventor based in Plano, TX (US). He has made significant contributions to the fields of phonetic modeling and speech recognition. With a total of 2 patents, Kondo's work has advanced the technology used in these areas.
Latest Patents
Kondo's latest patents include a "Method of phonetic modeling using acoustic decision tree." This innovative method involves forming triphone grammars from phonetic data, training triphone models, clustering triphones that are acoustically close together, and mapping unclustered triphone grammars into a clustered model. The clustering process utilizes a decision tree based on acoustic likelihood, allowing for user-definable sub-model clusters.
Another significant patent is "Speech recognition using clustered between word and/or phrase." This invention improves speech recognition by employing coarticulation between words and phrases. The method reduces the number of phonetic models needed for additional vocabulary by clustering inter-word and phrase models into a few classes. This approach has shown that the accuracy for Japanese speech recognition is nearly as effective as unclustered models while reducing the number of models by more than half.
