Title: Innovations by Kuen-Ying Ou
Introduction
Kuen-Ying Ou is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of voice technology, holding a total of five patents. His work focuses on enhancing audio systems through innovative noise cancellation techniques.
Latest Patents
One of his latest patents is a voice apparatus and dual-microphone voice system with noise cancellation. This invention illustrates a voice detector and a noise detector that simultaneously receive a first voice source and a second voice source. The system acquires a first main signal with a voice band and a second main signal with a burst noise band. A voice filter is employed to filter the voice signal of the first main signal, allowing a burst noise signal with minimal voice signal to remain. Conversely, a noise filter processes the burst noise signal of the second main signal to retain a voice signal with minimal burst noise. Additionally, a post-filter generates a noise reduction gain based on the remained voice and noise, adjusting the voice signal accordingly.
Another significant patent is related to a method and system for self-tuning active noise cancellation and a headset apparatus. This system involves placing the headset apparatus on a measurement device to emulate user scenarios. The STANC system receives environmental noise signals from a microphone within the headset, producing a reverse noise signal to suppress the environmental noise via a speaker unit. The calibration mode utilizes the error signal from the measurement device to update STANC parameters, ensuring optimal performance.
