【摘要】：主要通过比较目前主要的三种音频检测方式的优缺点,依据电台广播与广告的特点确定采用声纹比对的解决方法,并制定了广告智能监播系统架构。根据梅尔倒谱系数算法提取广告原始音频与录播音频、开路信号音频特征值并进行对比的基本原理,确定了广告智能监播系统的初步流程与架构。在实际测试中优化了设计方案,最终测试结果达到既定目标,解决了北京电台人工校验广告的问题,并为今后北京人民广播电台广告智能监播的进一步研发打好了基础。
[Abstract]:By comparing the advantages and disadvantages of the three main audio detection methods at present, according to the characteristics of radio broadcasting and advertising, the solution of voice-pattern comparison is determined, and the framework of advertising intelligent monitoring and broadcasting system is developed. According to the principle of extracting the original audio frequency and recording audio frequency by Mel cepstrum coefficient algorithm and comparing the audio eigenvalues of open circuit signal, the preliminary flow and structure of the advertising intelligent monitoring and broadcasting system are determined. In the actual test, the design scheme is optimized, the final test result reaches the established goal, the problem of manual check advertisement of Beijing Radio Station is solved, and the foundation is laid for the further research and development of the intelligent supervision and broadcast of the advertisement of Beijing people's Radio Station in the future.
