Title: The Innovations of Alexander Kain
Introduction
Alexander Kain is an accomplished inventor based in Portland, OR (US). He holds a total of 4 patents that showcase his expertise in speech synthesis and acoustic inventory compression. His work has significantly contributed to advancements in natural-sounding synthesized speech.
Latest Patents
One of Kain's latest patents is titled "Stochastic modeling of spectral adjustment for high quality pitch modification." This invention focuses on generating natural-sounding synthesized speech by utilizing pieced elemental speech units. The method involves setting line spectral frequencies (LSF) based on a correlation between the desired fundamental frequency and known LSF vectors for different phoneme classes. This correlation is established by analyzing recorded speech databases, allowing for more accurate speech synthesis.
Another notable patent is "System and method for compressing concatenative acoustic inventories for speech synthesis." This invention presents a novel approach to compressing acoustic inventories by leveraging multiple properties of these inventories. Instead of relying on general-purpose signal compression methods, Kain's method minimizes the size of acoustic inventories by utilizing the close acoustic match property. This innovation allows for reduced storage requirements, making it feasible to use smaller storage devices.
