摘要
Abstract
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.关键词
