摘要
在现有谱减算法的基础上,介绍一种改进多带谱减算法,通过实时端点检测算法对改进后的算法进行端点检测,共同形成可用于广播系统的改进语音增强算法。同时,根据改进的语音增强算法设计、实现广播系统,并对设计的系统进行测试分析,最终确认该广播系统具有高稳定性、高响应速度等特征,可满足应急广播使用需求。
Based on the existing spectral subtraction algorithm,an improved multi-band spectral subtraction algorithm is introduced,and real-time endpoint detection algorithm is used to detect the improved algorithm,together,they form an improved speech enhancement algorithm that can be used in broadcast system.At the same time,according to the improved speech enhancement algorithm,the design and implementation of the broadcasting system is implemented,and the system after the design and implementation is tested and analyzed,the utility model can meet the demand of emergency broadcasting.
