本文设计的具有语音播报GPS信息功能的电路系统，采用单片机读取GPS接收模块的定位信息，在进行分析处理后自动转换为控制代码，通过语音组合形成定位信息的语音播报。由于驾驶员开车过程中可以直接听到有关导航信息，减轻了靠眼睛观察的负担，从而提高了行车的安全性。-paper designed for the broadcast voice of the GPS function circuit system SCM using GPS receiver module reads the positioning information, analysis after automatically switch to control code, formed through the combination of voice positioning information broadcast speech. Because the drivers to drive the process can directly hear the navigation information on reducing the burden on the eyes, thus enhance traffic safety.
