Title: Innovations of Chau-Kai Hsieh
Introduction
Chau-Kai Hsieh is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of voice recognition technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and accuracy of voice recognition systems.
Latest Patents
One of his latest patents is titled "Endpoint detection in a stand-alone real-time voice recognition system." This invention describes a system that converts an analog voice signal into a serial digital signal. It preprocesses the digital signal in parallel to detect the end-point and outputs fixed multi-order prediction coefficients. These coefficients are stored as reference patterns during the training mode. In recognition mode, the coefficients are adapted using a modified dynamic time warping method, implemented with a one-dimensional circular buffer to save memory space. The adapted coefficients are then compared with the reference pattern to produce recognition results.
Another significant patent is "System architecture and method for linear interpolation implementation." This invention includes an interpolation circuit designed for a voice synthesizer that receives multiple frames of voice data. Each frame is subdivided into sub frames, each assigned a predefined interpolation weighting factor. The circuit comprises an input port for receiving sub frame voice data, a read-only memory (ROM) for storing multiplications of sub frame data with weighting factors, and an output means for computing an interpolation value.
