说明：  由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)
