This invention discloses a
secure voice-based intelligent customer
service system and
interaction method based on a multi-
agent architecture. The
system includes an ASR (
Automatic Speech Recognition) module, multi-layered security barriers, a main retrieval agent, a specialized retrieval agent cluster, a parallel retrieval and result aggregation module, an LLM (Limited Language Modeling) synthesis engine, and a TTS (Text-to-Speech) module. Through multi-agent
system architecture and methodological design, this invention achieves modular
processing, parallel retrieval tasks, and closed-loop security control. By enabling independent calls between input, output, agents, and
inference stages via multi-layered security barriers, the
system effectively mitigates risks such as prompt word injection,
indirect injection attacks, harmful
content generation, and
information leakage. Sensitive information identification, access permission
verification, and content compliance review are embedded in each stage of input, retrieval,
information synthesis, and output to prevent sensitive data leakage and meet the application requirements of high-security business scenarios (such as finance,
telecommunications, and government services).
