Title: Innovations by Hu Chen in Voice Capture Technology

Introduction

Hu Chen is an accomplished inventor based in Cremorne, Australia. He has made significant contributions to the field of signal processing, particularly in the development of advanced voice capture technologies. With a total of two patents to his name, Hu Chen's work focuses on enhancing the performance of headsets through innovative designs.

Latest Patents

Hu Chen's latest patents include a "Flexible voice capture front-end for headsets" and a "Wind noise reduction with beamforming" device. The first patent describes a signal processing device that features configurable voice activity detection. This device utilizes multiple inputs to receive microphone signals, which are then routed by a microphone signal router. The voice activity detection module analyzes these signals to determine the presence of speech or noise. Additionally, a spatial noise reduction module performs adaptive beamforming to output a noise-reduced signal, allowing for simple configurability across various headset designs.

The second patent focuses on wind noise reduction and spatial noise reduction. It employs a first microphone to capture speech and a second microphone for noise. The device incorporates a generalized sidelobe canceller that adaptively processes the speech signal to create a cancellation signal. This signal is then used to filter out noise, resulting in a clearer speech reference signal. The wind noise reduction module further enhances the device's capabilities by utilizing filters derived from the generalized sidelobe canceller.
