摘　　要：传统声码器的话音接口单元需要的电源种类多、体积大,无法做到小型化。基于单+5 V供电的小型化声码器的实现方案无需外接铃流及馈电单元,采用开关电源升压和恒流。简要介绍了硬件实现原理、软件设计流程,详细阐述了需要解决的问题和关键技术,对设计的性能测试进行了优缺点分析,提出了灵活应用的改进意见,并给出了设计的应用领域。The voice interface unit of traditional vocoder needs multiple types of power supply and more volume, so it can not be miniaturized. A miniaturized vocoder is proposed, which is based on user interface unit of a single ＋ 5V power supply without outside ringing source and battery feed. It adopts switching power boosting and constant current. The hardware scheme and software design of the vocoder are briefly introduced, and the issues to be addressed and the key techniques are particularly described. The advantages and disadvantages of the design performance are analyzed, and the improving suggestions and the application field are also presented.
