Title: Yoichi Ichikawa: Innovator in Voice Recognition Technology
Introduction
Yoichi Ichikawa is a notable inventor based in Ebina, Japan. He has made significant contributions to the field of voice recognition technology. His innovative approach has led to the development of a unique voice recognition system that utilizes the centroid of frequency spectra.
Latest Patents
Ichikawa holds a patent for a voice recognition system that employs the locus of the centroid of vocal frequency. This system analyzes the frequency spectra of a voice to identify characteristic parameters. By measuring the average frequency and amplitude during the utterance of a selected phrase, the system creates a pattern stored in memory. During recognition, the user inputs a known address to retrieve the stored pattern and reutters the key phrase. The system then recalculates the centroid of frequency spectra and compares it with the stored locus, defining a "humming distance" to assess accuracy.
Career Highlights
Ichikawa is currently associated with Fuji Xerox Co., Ltd., where he continues to innovate in the field of voice recognition. His work has garnered attention for its potential applications in various industries, enhancing user interaction with technology.
