用语音互动讲黄河文化，智能回答+数字人播报
RiverEcho: Real-Time Interactive Digital System for Ancient Yellow River Culture
- 基于大模型与文化知识库，实现语音问答响应
- 结合RAG提升回答专业性，生成更准确内容
- 适合文化传播、教育科普场景使用
黄河是中国的母亲河，也是人类文明的摇篮。古代黄河文化是人类艺术史不可或缺的部分。为保护与传承古代黄河文化，我们设计了RiverEcho——一个实时交互系统，通过大语言模型和文化知识数据集，响应语音查询，并由数字人形象进行讲解。具体而言，我们构建了聚焦古代黄河文化的知识数据库，包含历史文献采集与处理流程。实验表明，在所提数据集上采用检索增强生成（RAG）可显著提升大语言模型的响应质量，使系统输出更具专业性与信息量。本工作不仅丰富了黄河文化传播手段，也为用户提供更深入的文化洞察。
原文摘要 · Abstract (English)
The Yellow River is China's mother river and a cradle of human civilization. The ancient Yellow River culture is, moreover, an indispensable part of human art history. To conserve and inherit the ancient Yellow River culture, we designed RiverEcho, a real-time interactive system that responds to voice queries using a large language model and a cultural knowledge dataset, delivering explanations through a talking-head digital human. Specifically, we built a knowledge database focused on the ancient Yellow River culture, including the collection of historical texts and the processing pipeline. Experimental results demonstrate that leveraging Retrieval-Augmented Generation (RAG) on the proposed dataset enhances the response quality of the Large Language Model(LLM), enabling the system to generate more professional and informative responses. Our work not only diversifies the means of promoting Yellow River culture but also provides users with deeper cultural insights.
