Title: The Innovations of Etienne Barnard
Introduction
Etienne Barnard is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of speech recognition technology. With a total of 5 patents to his name, Barnard's work has advanced the capabilities of acoustic modeling and dynamic semantic control in speech recognition systems.
Latest Patents
One of Barnard's latest patents is titled "Method and apparatus for discriminative training of acoustic models of a speech recognition system." This invention provides a method for automatically training or modifying models of acoustic units in a speech recognition system. The process involves comparing segment alignment data to identify erroneous segments and adjusting acoustic models accordingly. This leads to more optimal values based on empirical utterance data representing recognition errors.
Another significant patent is "Dynamic semantic control of a speech recognition system." This invention allows for the automatic recognition of spoken words using a computer-based speech recognition system that operates according to a dynamic semantic model. The system generates word strings and assigns probability values to them, which can be modified based on external conditions. This adaptability enhances the accuracy of speech recognition in varying contexts.
