我正在编写用于GUI的程序，以使用tkinter支持我的Voice Assistant Python脚本。但是问题在于，一旦激活了语音助手程序，即会不断执行用户所说内容的功能的无限循环，整个窗口冻结，我无法单击任何其他按钮，而且我无法也访问关闭（X）按钮。我知道在这种情况下我需要使用线程，但是我并不清楚要在哪里使用它来实现我的期望。如果有人可以帮助我，我将非常有义务。我将提供为帮助您解决问题而编写的全部代码。程序中的无限运行功能为Geega()

您在这里考虑穿线是正确的。
标准线程库就足够了。您将要创建两个类，一个用于GUI，另一个用于其他进程。您可以对函数执行以下操作：
import threading
...
class BackgroundProcess(threading.Thread):
def __init__(self, parent=None):
super().__init__()
self.parent = parent
def run(self):
Geega()
并且不只是从您的UI调用Geega（），而是创建一个新的BackgroundProcess对象并按如下所示调用其start（）函数：
process = BackgroundProcess()
process.start()
希望这会有所帮助！
