Threading with Tkinter and Speech to Text

Question

I have to do the threading in 1 of 2 codes; one is of speech to text conversion and other is of Tkinter GUI and they both are interrelated that if one says something then it has to perform some changes in GUI. Problem is that when I make thread GUI and speech in mainloop, it works fine until I execute the condition that if someone says "HOME" u have to show new button in GUI; it gives an error that MAIN THREAD is not in main loop And when I try to keep Speech code in thread and GUI in mainloop; it gives an error that "SIGNAL should be in mainloop" If I keep both in the main loop and don't do threading then if GUI is written first then it shows GUI and stuck there and if speech is written first it keeps running the speech code(since it is infinity FOR loop)

The code works fine until I put if cond,

Shows this error,
