Title: The Innovative Contributions of Sean S You
Introduction
Sean S You is a prominent inventor based in Chandler, AZ (US), known for his significant contributions to the field of speech processing technology. With a total of 7 patents to his name, he has developed innovative methods and apparatuses that enhance the encoding and synthesis of speech excitation waveforms.
Latest Patents
One of his latest patents is a method and apparatus for encoding speech excitation waveforms through a vocoder device. This invention characterizes and reconstructs speech excitation by performing a cyclic excitation transformation process on a target excitation segment. The excitation phase representation is dealiased using multiple dealiasing passes based on the phase slope variance. Both primary and secondary excitation components are characterized, with the secondary excitation being based on the computation of the error between the characterized primary excitation and the original excitation. Alternatively, an excitation pulse compression filter is applied to the target, resulting in a symmetric target that is characterized by normalizing half of it. The synthesis portion of this invention performs reconstruction and synthesis of the characterized excitation based on the employed characterization method.
Another notable patent by Sean S You is a method and apparatus for the synthesis of speech excitation waveforms. This speech vocoder device synthesizes speech excitation waveforms by reconstructing an excitation target from decoded speech data. The method involves creating aligned excitation segments by normalizing, correlating, and aligning a source segment and a target segment. It also includes reconstructing normalized intervening segments through ensemble interpolation and denormalizing these segments to reconstruct an excitation waveform.
