| 摘 要： | 随着社会经济与科技的发展,模拟对讲机已经不能满足市场的需求。目前我国正在积极展开自主知识产权的数字对讲机的研发工作,以及数字对讲机协议的制定。通过对二元激励线性预测编码、正弦激励线性预测、多带激励、混合激励线性预测的合成语音质量进行比较和分析,提出在数字对讲机中采用混合激励线性预测编码算法处理语音信号的方案,并通过Matlab软件进行了仿真验证,结果表明该方案能满足数字对讲机的要求。

| Abstract: | With the development of social economy and technology,the analog intercom could not satisfy the market demand.Nowadays,the Chinese researchers focus on the development of independent digital intercom and its protocol.By comparing the speech qualities composed by LPC,SELP,MBE and MELP,the application of MELP in the digital intercom is proposed.and the simulation and experiment with Matlab indicate that this scheme is feasible and could satisfy the requirement of digital intercom. |
