sr.Recogniser.listen() does not work and stalls

Steps to reproduce

This code does not get past getting audio from the microphone: `import speech_recognition as sr

r = sr.Recognizer() m = sr.Microphone()

try: print("A moment of silence, please...") with m as source: r.adjust_for_ambient_noise(source) print("Set minimum energy threshold to {}".format(r.energy_threshold)) while True: print("Say something!") with m as source: audio = r.listen(source) print("Got it! Now to recognize it...") try: # recognize speech using Google Speech Recognition value = r.recognize_google(audio)

        # we need some special handling here to correctly print unicode characters to standard output
        if str is bytes:  # this version of Python uses bytes for strings (Python 2)
            print(u"You said {}".format(value).encode("utf-8"))
        else:  # this version of Python uses unicode for strings (Python 3+)
            print("You said {}".format(value))
    except sr.UnknownValueError:
        print("Oops! Didn't catch that")
    except sr.RequestError as e:
        print("Uh oh! Couldn't request results from Google Speech Recognition service; {0}".format(e))

except KeyboardInterrupt: pass`

Expected behavior

Should advance to recognition: value = r.recognize_google(audio)

Actual behavior

with m as source: audio = r.listen(source), even after speaking, does not advance to the next line.
