Kivy Voice recognition is not converting speech to text

my code is recording voice, but for some reason google recognizer or sphinx not converting the voice to text. If i print the audio there is voice. the output is "Sorry, I did not get that" witch is the exception default. Can you look in to my code and see what I'm doing wrong. In regular Python this Voice recognition work fine. `

from kivy.app import App
from kivy.clock import Clock
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.clock import Clock, mainthread
import speech_recognition as sr
from kivy.lang import Builder
from plyer import stt
from plyer import tts

Builder.load_string("""
<Principal>:
    id: HomeScreen
    BoxLayout:
        orientation: 'vertical'
        Button:
            text:'speak'
            on_release: root.Btnclick()
        Label:
            id: lblMessage
            text: 'Hello' """)

class Principal(Screen):
    def Btnclick(self):
        self.ids.lblMessage.text = "Say something!"
        Clock.schedule_once(lambda d: self.GetAudio(), 0)
 
    def GetAudio(self):
        r = sr.Recognizer()
        r.energy_threshold =4000
        r.dynamic_energy_threshold = True
        
        with sr.Microphone() as source:
            r.adjust_for_ambient_noise(source,duration=5)
            #r.energy_threshold = 400  
            r.dynamic_energy_threshold = True 
            print("Say something!")  
            audio = r.listen(source)
        try:
            print("you Said: "+r.recognize_sphinx(audio, language = "en-US"))
            #tts.speak("you Said: "+r.recognize_sphinx(audio, language = "en-US"))
            self.ids.lblMessage.text = "you Said: "+r.recognize_sphinx(audio, language = "en-US")
        except:
            print("Sorry, I did not get that")
            #tts.speak("Sorry, I did not get that")
            self.ids.lblMessage.text = "Sorry, I did not get that"

class MainApp(App):
 
    def build(self):
        for i in sr.Microphone.list_microphone_names():
            print(i)
        sm = ScreenManager()
        self.sm = sm
        sm.add_widget(Principal(name='Principal'))
        return sm
 
    def on_pause(self):
        return False
                
if __name__ == '__main__':
    MainApp().run()

This is the output am getting
