这个是WT588D的语音处理程序. 一线控制发音.相当的不错-This is the voice WT588D process. First-line control of pronunciation. Very good

本设计介绍了基于单片机控制的超声测距的原理：由STC89C52控制定时器产生一定频率脉冲，计算从发射到接收回波时间，从而得到实测距离，数据处理采用，lcd1602显示距离，WTD588D语音播报。-This design introduces MCU control based on the principle of ultrasonic distance measurement: STC89C52 controlled by a timer to generate a certain freq
