python speech recognition in Tkinter

You need to use threading to run a proper concurrent speech-recognition, and update the text-widgets contents using the after-method, because Tkinter doesn't support threading in a different manner.

I don't have speech-recognition working here, so you need to fill in the blanks and replace the random.choice-call with your actual speech-recognition.

 import threading import time import random from Tkinter import * import tkMessageBox import Tkinter as tki import tkFileDialog as th1 class SpeechRecognizer(threading.Thread):     ANSWERS = ["foo", "bar"]     def __init__(self):         super(SpeechRecognizer, self).__init__()         self.setDaemon(True)         self.recognized_text = "initial"     def run(self):         while True:             time.sleep(1.0)             self.recognized_text = random.choice(self.ANSWERS) recognizer = SpeechRecognizer() recognizer.start() class App(object):     def __init__(self,root):         self.root = root     # create a Frame for the Text and Scrollbar         txt_frm = tki.Frame(self.root, width=900, height=900)         txt_frm.pack(fill="both", expand=True)         # ensure a consistent GUI size         txt_frm.grid_propagate(False)     # create first Text label, widget and scrollbar         self.lbl1 = tki.Label(txt_frm, text="Type")         self.lbl1.grid(row=0,column=0,padx=2,pady=2)         self.recognized_text = StringVar()         self.txt1 = tki.Text(txt_frm, borderwidth=3, relief="sunken", height=4,width=55,         )         self.txt1.config(font=("consolas", 12), undo=True, wrap='word')         self.txt1.grid(row=25, column=7, sticky="nsew", padx=2, pady=2)         root.after(100, self.update_recognized_text)     def update_recognized_text(self):         self.txt1.delete(0.0, END)         self.txt1.insert(0.0, recognizer.recognized_text)         root.after(100, self.update_recognized_text)     def clearBox(self):         if a == "clear":             self.txt1.delete('1.0', 'end') root = tki.Tk() app = App(root) root.mainloop()
