Title: Xiangyu Sun and Voice Interaction Technology.

Introduction

Xiangyu Sun is an inventor based in Shanghai, China, associated with Espressif Systems (Shanghai) Pte Ltd. Her patent work addresses automatic gain control for voice interaction systems, with a method designed to help maintain picked-up audio at a preset volume range.

Latest Patents

Sun is named on one patent: “Automatic Gain Control Method and Apparatus for Voice Interaction System, and System.” The disclosed method receives a voice signal and uses blind source separation to divide it into sound signals from different sources. A pretrained wake-up-word detection model then checks each signal to identify the one containing a wake-up word. Based on that signal, the system calculates the gain needed to adjust the picked-up audio volume to a preset range. The patent also describes an apparatus, a system, and a computer-readable storage medium related to the method. Sun’s listed patent count is 1 patent.
