not getting desired results using hyp() function

hi,
i used below code for speech recognition

import pyaudio
import wave
import sphinxbase

try:

except ValueError:

BASE_PATH = os.path.dirname(os.path.realpath(file))
print(BASE_PATH)
HMDIR = os.path.join(BASE_PATH, "hmm")
print(HMDIR)
LMDIR = os.path.join(BASE_PATH, "lm/en-us.lm.bin")
print(LMDIR)
DICTD = os.path.join(BASE_PATH, "dict/cmu07a.dic")
print(DICTD)

CHUNK = 128

device_index = 4

    for keyword in tags:

            device_index = i
            return device_index

if device_index is None:
    print("No preferred input found; using default input device.")

return device_index

def save_audio(wav_file):

    format=FORMAT,
    channels=1,
    rate=RATE,
    input=True,
    frames_per_buffer=CHUNK,
    input_device_index=device
)

print("* recording")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)

print("* done recording")

stream.stop_stream()
stream.close()

wf.writeframes(b''.join(frames))
wf.close()

def transcribe(fp):

config = pocketsphinx.Decoder.default_config()
config.set_string('-hmm', HMDIR)
config.set_string('-lm', LMDIR)
config.set_string('-dict', DICTD) 
decoder = Decoder(config)

speech_rec = pocketsphinx.Decoder(config)
opened_file =  open(fp)
print("\n""types results",type(opened_file),"\n\n")

opened_file.seek(44)
data = opened_file.read()
print("value of data",data)
decoder.start_utt()
decoder.process_raw(data, False, True)
print("value of process_raw",decoder.process_raw(data, False, True))
#decoder.end_utt()
result = decoder.hyp()
print("our results",result)
transcribed = [result]
logging.info('PocketSphinx ?????%r', transcribed)
return transcribed

if name == 'main':
save_audio(WAVE_OUTPUT_FILENAME)
print(type(WAVE_OUTPUT_FILENAME))
result = transcribe(WAVE_OUTPUT_FILENAME)
print "You just said: {0}".format(result[0])

i didn,t get any error but also not getting OUTPUT below is results when i say "hello world"

i want : to be written text "hello world" after You just said:

You just said: None

waiting for your valuable reply
thanks in advance

i think the reason is that decoder.hyp() does not contains anything will someone please suggest that what to do
