本文主要是介绍qcc更换语音提示的方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
这里就不做图片说明，按照步骤做出来更加有成就感。
1.用adk configuration tool添加语音，并且导出语音文件（会生成headers prompts两个文件夹）
2.使用packfile命令将生成的文件夹合并为xuv语音文件（比如vp.xuv）
3.使用nvscmd命令导出ptn文件（nvscmd dump xxx.ptn），可以看到分区，如果有原始项目不需要做此步骤，找到语音分区（这里默认是3）
4.使用nvscmd命令烧录语音分区，这里假设3是语音分区（默认ptn的3分区就是语音），命令为 nvscmd burn xxx.ptn 3
