  File "C:/Users/punna/PycharmProjects/alex/alex.py", line 6, in <module>
    audio = r.listen(source,timeout=2)
  File "C:\Users\punna\Anaconda3\lib\site-packages\speech_recognition\__init__.py", line 544, in listen
    raise WaitTimeoutError("listening timed out while waiting for phrase to start")
speech_recognition.WaitTimeoutError: listening timed out while waiting for phrase to start

I wrote exception but it is again giving error

can anyone help me

It is because you kept the timeout for a limited amount of time. Try without the timeout or keep the timeout at least more than 5
