Title: Ryosuke Isotani: Innovator in Noise Suppression Technology
Introduction
Ryosuke Isotani is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of noise suppression technology, holding a total of 7 patents. His work focuses on developing advanced systems and methods that enhance audio quality by effectively reducing unwanted noise.
Latest Patents
Isotani's latest patents include a noise suppression system, a noise suppression method, and a recording medium storing program. The noise suppression system features an a priori S/N ratio estimated value and expectation calculation unit that acquires an expectation of a priori S/N ratio. This is achieved by correcting an estimated value of the a priori S/N ratio related to a signal and noise based on a priori S/N ratio models or signal and noise models. The system also includes a noise suppression coefficient calculation unit that calculates a noise suppression coefficient using the expectation of the a priori S/N ratio. Finally, a noise suppression unit suppresses the noise in the input signal by multiplying it by the noise suppression coefficient.
Another notable patent is the speech processing apparatus, which includes an expectation value calculation unit. This unit calculates a spectrum expectation value using an input signal spectrum and a speech model that represents the features of speech. Additionally, an acoustic power estimation unit estimates the acoustic power of the acoustic component based on the input signal spectrum and the spectrum expectation value.
