Title: **Innovations of Xuefei Gong in Voice Conversion Technology**

Introduction

Xuefei Gong is an accomplished inventor based in Jiangsu, China, known for his innovative contributions in the field of voice conversion technology. With two patents to his name, Gong's work focuses on enhancing speech recognition systems, particularly under challenging resource conditions.

Latest Patents

Gong's recent patents include a **Voice Conversion System and Training Method Therefor**. This invention proposes a novel speech conversion strategy that relies on non-parallel corpus training. It aims to eliminate the dependence on parallel text for voice conversion, thus addressing the limitations faced in resource-constrained environments. The proposed voice conversion system not only allows for the use of a trained speaker-independent automatic speech recognition model but also introduces bottleneck features that abstract audio in a manner that decouples spoken content from the speaker's timbre. This significantly improves pronunciation accuracy compared to previous methods that relied on phonetic posteriorGram features. Additionally, his method reduces the necessity for extensive training corpora through a transfer learning approach.

Another of Gong's patents revolves around a **Method and System for Outputting Target Audio, Readable Storage Medium, and Electronic Device**. This invention involves the utilization of a phonetic posteriorgram (PPG) classification network to generate PPG feature vectors from source audio, which encapsulate both text and prosodic information. The subsequent processing through a voice conversion network efficiently produces target audio with varying timbres, showcasing Gong’s commitment to advancing audio processing technologies.
