Arduino2560和Syn6628语音芯片做语音播报系统，loop程序不严密,怎么修改程序结构？
关于程序结构的求助。
第一次接触Arduino，想要结合Syn6628语音芯片，做一个语音播报系统。
其中播放的 语音子函数speech(1,2,3,4) 是由Arduino_LPTTS函数生成器生成。通过按一个键
输出一个相应的语音。现在的问题是
loop函数中该怎么调用speech(1,2,3,4)，我写的程序太简单，有一些有问题。当正播放一个语音时，按下另一个按键以播放另一句语音时，有6、7秒的反应时间，而且有时会进入死循环。该怎么修改程序结构解决这些问题，请各位高手指教。
程序如下：
int key1=4;//按下该键播放语音语音1
int key2=5;//按下该键播放语音语音2
int key3=6;//按下该键播放语音语音3
int key4=7;//按下该键播放语音语音4
int state1=0;
int state2=0;
int state3=0;
int state4=0;
//语音子函数speech(1,2,3,4) 是由Arduino_LPTTS函数生成器自动生成
//1、黄绮珊 剪爱
