Title: Inventor Masataka Nakamura: Pioneering Innovations in Speech Detection and Signal Processing

Introduction

Masataka Nakamura, an accomplished inventor based in Hiroshima, Japan, has made significant contributions to the fields of speech detection and signal processing. With two patents to his name, Nakamura's work reflects a commitment to advancing technology in audio processing.

Latest Patents

Nakamura's latest inventions showcase his expertise in developing sophisticated audio technology. His first patent, the "Speech Section Detection Apparatus," introduces a method capable of reliably detecting speech segments even when dealing with challenging sounds, such as glottal stops and specific s-column or h-column phonetics in the Japanese Goju-on Zu syllabary. This apparatus employs a microphone to detect speech signals, which are then amplified, converted from analog to digital, and stored in memory. A pitch detection process subsequently extracts speech pitch to control a gate signal generator, allowing for accurate segmentation of speech signals.

His second patent, titled "Low-Noise Active RC Signal Processing Circuit," describes an advanced signal processing circuit designed to minimize noise. The innovation includes a feedforward section that operates to provide output at a predetermined gain and a feedback section that ensures the output is negatively fed back to the input signal, thereby enhancing transfer characteristics. This invention aims to achieve a low Q-value while maintaining outstanding low-noise performance, making it highly relevant for modern electronic applications.
