智能音频检索技术在侦收系统中的应用研究

摘要

为提高各类侦收系统的自动化程度，提出基于智能音频检索技术的侦收设备工作原理，讨论其特点，并给出提高检索效率的方法以及语种识别、关键词检索、关键字语音检索、关键音频检索及关键说话人检索等工作模型。对于基于移动通信网的多通道、基于无线电侦测的单通道侦收系统和internet等公共信息网，分别给出了智能音频检索技术应用的工作原理框图及实现方式，希望研究结果能够对信息监管起到重大的推动作用，最终达到为国家安全服务的目的。%In order to increase electronic reconnaissance receiving and processing system automation, its working principle based on intelligent audio information retrieval technology was proposed and its characteristics was discussed.These methods for improving the retrieval efficiency was given. Language identification、keyword spotting、keyaudio spotting and keyspeaker verification working principle model were proposed. These working principle diagrams based on intelligent audio information retrieval system of electronic reconnaissance receiving and processing system based on both the multi-channel mobile communication network and the single channel radio detection system and public information network such as Internet are presented. It is hoped that this research results can play a major role of information supervision,and eventually serve for the national security.
