Title: Innovations of Dongil Hyun in Speech Processing Technology
Introduction
Dongil Hyun is a notable inventor based in Incheon, South Korea. He has made significant contributions to the field of speech processing, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a speech processing apparatus and method using a plurality of microphones. This apparatus includes multiple microphones designed to receive various input signals. The processing circuitry generates a spatial filtering signal corresponding to these input signals through spatial filtering. It also integrates directional noise information with diffuse noise information to generate estimated noise information. This allows for the creation of an estimated speech signal by filtering the spatial filtering signal based on the estimated noise information.
Another significant patent is a residual echo estimator that estimates residual echo based on time correlation. This estimator evaluates the magnitude of residual echo from a microphone signal input, which is output through a speaker. It uses the magnitude of linear echo from both the current and past frames to estimate the residual echo and updates the weights applied to these magnitudes.
