Speech Recognition UnknownValueError

I have tried it on python shell 3.5.8

import speech_recognition as sr
import webbrowser as wb

chrome_path = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe 
%s'


# obtain audio from the microphone  
r = sr.Recognizer()  
with sr.Microphone() as source:  
   print("Please wait. Calibrating microphone...")  
   # listen for 5 seconds and create the ambient noise energy level  
   r.adjust_for_ambient_noise(source, duration=5)  
   print("Say something!")  
   audio = r.listen(source)  

# recognize speech 
try:
    text = r.recognize_google(audio)
    print("I thinks you said '" + r.recognize_google(audio) + "'")

    f_text='https://www.google.co.in/search?q=' + text
    wb.get(chrome_path).open(f_text)
#except sr.UnknownValueError:  
#  print("I could not understand audio")  
except sr.RequestError as e:  
   print("error; {0}".format(e))

except Exception as e:
   print (e)

Here's an excerpt from an example in SpeechRecognition repo:

except sr.UnknownValueError:
    print("Google Speech Recognition could not understand audio")

Try below code.

import speech_recognition as sr
from os import walk

r = sr.Recognizer()
#optional
#r.energy_threshold = 300

def startConvertion(path = 'file.wav', lang = 'en-IN'): 
    with sr.AudioFile(path) as source:
        #print('Fetching File')
        audio_file = r.record(source)
        print(r.recognize_google(audio_file, language=lang))
startConvertion()

try this out

try:
    text = r.recognize_google(audio, language = 'en-IN', show_all = True )
    print("I thinks you said '" + r.recognize_google(audio) + "'")

    f_text='https://www.google.co.in/search?q=' + text
    wb.get(chrome_path).open(f_text)

I think this is happen because of noise interrupts algorithm. due to noise it gives UnknownValueError
