Script stuck on hotword detection

[furqanahmedmtbc]

Steps to reproduce

I try to run the following script but it seems it is stuck on wake-word detection. I have spoken multiple times but the script does not seem to recognize the wake-word. (Note: The recognition works fine without the wake-word part, It just seems like the addition of wakeword requirement is not working.)

I'm using the Google cloud Speech API on a Raspberry Pi 3.

Code:

pmdl = ['/home/pi/AoD_Final/V4/Squeak.pmdl']
sbLoc = '/home/pi/AoD_Final/V4/'
sbCfg = (sbLoc,pmdl)

print(sbCfg)

# use the audio file as the audio source
mic = sr.Microphone(device_index=3)
r = sr.Recognizer()

print("A moment of silence, please...")
with mic as source:
    r.adjust_for_ambient_noise(source)
    print("Set minimum energy threshold to {}".format(r.energy_threshold))

with mic as source:
    r.adjust_for_ambient_noise(source)
    #r.snowboy_wait_for_hot_word(source, "/AoD_Final/V4", "Squeak.pmdl", source, timeout=None)
    audio = r.listen(source,snowboy_configuration=("/home/pi/AoD_Final/V4",["/home/pi/AoD_Final/V4/Squeak.pmdl"]))
    #audio = r.listen(source,snowboy_configuration=sbCfg)
    #audio = r.listen(source)

I did some digging around. Looks like the scrip is stuck on snowboy_result = detector.RunDetection(b"".join(resampled_frames)) in the speech recognition init file. The "_snowboyresult" value remains 0 even after speaking into the mic multiple times. The hotword is supposed to be detected when this value goes above 0. Any idea how I can solve this issue?
