摘　　要：针对某船用通信耳罩在强环境噪声条件下,语音通信受严重影响甚至无法正常工作的问题,构建某船用语音通信系统架构和模型,提出一种联级型语音增强算法,分析系统参数对控制效果的影响,并搭建高性能噪声控制验证平台对所述算法进行验证。结果表明,所提出的算法的能有效降低麦克风语音通讯时强环境噪声干扰,提升语音通信信噪比,显著消除粉色噪声和线谱噪声的不利影响,降低人员移动时参考信号不稳定性对控制效果的影响,可为通讯系统耳罩改进提供技术参考。Aiming at the problem that the voice communication of a marine communication earmuff is seriously affected,or even cannot work normally under the condition of strong environmental noise,the architecture and model of a marine voice communication system were constructed,and a cascaded voice enhancement algorithm was proposed to analyze the influence of the system parameters upon the control effect.A high-performance noise control verification platform was built to verify the algorithm.The results showed that the proposed cascaded speech enhancement algorithm can effectively reduce the strong environmental noise interference during microphone speech communication,and improve the signal-to-noise ratio of speech communication,significantly eliminate the adverse effects of pink noise and line spectrum noise,and reduce the influence of reference signal instability on the control effect when the crew is moving.All of which can provide a technical reference for the improvement of the earmuffs of the later communication system.
