Question

我想在代码中进行语音识别。我在此代码中使用了多个框架。起始页实际上仅是用于启动应用程序的菜单。在startPage中有一个用于启动应用程序的按钮。之后，将出现PageOne。但是我想在第一页做语音识别。如果我调用了Speechh函数，则在运行代码后，语音识别将立即开始。我想问我如何做才能使语音识别从单击开始页面中的按钮后的第一页开始？

最后删除语音通话，将command=lambda: controller.show_frame("PageOne"),更改为command=controller.on_start,，并在show_frame方法附近添加此方法：

def on_start(self):
    self.show_frame("PageOne")
    speech()

显示框后如何调用函数？
