程序说明
该程序是继我上一次调用科大讯飞语音合成离线SDK，用Python写了一个文本转语音的程序的进一步开发，这次开发是用pyqt5模块和其自带的designer做了一个gui界面。
程序展示
该程序我分为了三大板块进行编写，第一板块是对科大讯飞语音合成离线的SDK，第二板块是对调用pyqt5对gui界面的编写，第三板块是主函数的编写。
第一板块SDK的调用

第二板块gui界面的编写

第三板块主函数的编写

总结
该程序还存在一些问题，比如第一次语音转换之后，第二次使用时输出框依然显示转换成功，无法确定第二转换成功的确切时间。输出的文件名无法在gui进行变动和无法使文件保存在使用者想保存的文件夹。这些等等将在以后的文章里进一步完善。
