Title: Fumihiro Yato: A Pioneer in Speech Recognition Innovations

Introduction

Fumihiro Yato, a prominent inventor based in Tokyo, Japan, has made significant contributions to the field of speech recognition technology. With a remarkable portfolio of five patents, Yato's innovations are not only groundbreaking but also practical, as they aim to enhance the accuracy and efficiency of recognizing spoken language.

Latest Patents

Among Yato's latest inventions is a highly efficient speech recognition system designed to determine a recognition result more quickly without compromising accuracy. This system reduces the necessary calculations involved in recognizing user speech, thereby shortening recognition times. It works by successively calculating statistical probabilities of acoustic models and can output a one-sentence recognition result whenever the model with the highest reliability is detected, ceasing further calculations to optimize processing time.

In addition, Yato has developed a speech recognition method aimed at recognizing input speech from a diverse range of speakers. This method employs feature parameters that represent both the short-time average spectrum envelope characteristic of the input speech and regression coefficients derived from the outputs of a wide-band filter bank. These regression coefficients indicate the general directionality of changes in the speech signal's spectrum. By measuring the distance between the feature parameters and stored standard patterns, the method identifies the recognized input speech based on the closest match.

Career Highlights

Yato has a noteworthy career with experience in notable companies such as Kokusai Denshin Denwa Co., Ltd. and Kokusai Denshin Denwa Kabushiki Kaisha. His work in these organizations has equipped him with a deep understanding of communication technology and reinforced his innovative spirit.
