使用51系列的控制ISD1760实现语音组合播放，前提对ISD1760的语音存储原理、语音信息地址分布机理要有足够了解。完成这些准备工作后，就是录音，制作样品，提取每段语音信息的地址信息，根据这些地址信息去编写51的控制程序。一般做法，存储在ISD1760中的语音有“0~9，一些英文字母，比如E（代替13层），叮咚提示音，还有欢迎词，欢送词，运行方向提示等”这些语音字段是语音组合播放的基础信息。这一切完成后，就该用51去组合调用这些声音，以达到播放例句“叮咚！1层到了，请走好”等等不同情形下的语音提示内容。

能实现语音组合播放的语音芯片很多，比如PM66智能语音芯片，WD588D语音模组等，这些芯片的开发比ISD便利很多，性能也稳定。

你好！

1、首先 isd1760 只是一个语音芯片，不具备MCU的功能

2、isd1760 接入单片机，然后用单片机发指令控制芯片

3、上位机通过串口和单片机连接，通过上位机间接控制芯片
