Title: Innovations and Contributions of Hyung Min Park in the Field of Speech Recognition and Signal Processing
Introduction: Hyung Min Park is a prolific inventor based in Seoul, South Korea, known for his significant contributions to the fields of speech recognition and signal processing. With a remarkable portfolio of 26 patents, he has developed groundbreaking technologies that enhance the extraction and processing of target signals.
Latest Patents: Among his latest inventions are two notable patents. The first is titled "Beamforming method using online likelihood maximization combined with steering vector estimation for robust speech recognition, and apparatus therefor." This invention focuses on a target signal extraction apparatus that includes a steering vector estimator and a beamformer. The steering vector estimator generates an input signal covariance based on frequency input results over time and a noise covariance according to variance derived from those results. This dual approach enhances the extraction performance of a target sound source by continually updating the beamforming weight.
The second patent, "Apparatus and method for generating excitation signal for resolver," discloses an innovative apparatus designed for excitation signal generation. It utilizes a sine wave generator and an amplifier that work synergistically to convert the sine wave into a differential signal. This differential signal is then driven into a coil to produce an excitation signal, progressively increasing voltage during the transient response interval.
Career Highlights: Hyung Min Park’s career includes notable tenures at esteemed organizations such as the Industry-University Cooperation Foundation at Sogang University and LG Innotek Co., Ltd. His work in these organizations has allowed him to collaborate on several advanced projects that have contributed to his wealth of patents and innovations.
