DataFun Summit 2023: Large Models, AIGC, and Voice Cloning for AI Sales Assistants

DataFun Summit 2023, titled "Large Models and AIGC Summit," was held on June 17‑18, 2023, offering eight specialized forums including foundational models, large language models, reinforcement learning, multimodal AIGC, training and inference, knowledge enhancement, intelligent Q&A, and information extraction and retrieval.

The summit featured more than 30 frontline experts in large models and AIGC who shared deep insights through live streaming sessions.

One of the highlighted talks was delivered by Zhou Wei, head of the Voice Algorithm Department at 58.com TEG‑AI Lab, focusing on "Voice Cloning Technology in AI Sales Assistants." Zhou holds a master’s degree from the University of Chinese Academy of Sciences and has extensive experience in speech recognition, synthesis, and AI product development.

In his presentation, Zhou described how 58.com’s AI sales assistant leverages natural-sounding, comfortable, and familiar voice clones to enhance conversational effectiveness. He introduced a few‑shot, multi‑speaker, multi‑accent voice cloning solution, discussed naturalness optimization under real dialogue data—including audio quality, stability, and text‑style transfer—and briefly outlined the deployment approach for the voice cloning service.
