hi
i want speech recognition using sphinx but as the accuracy of sphinx is not good at all. so need to decode the wav file but getting some error into the file....can any one please help me on this.
please tell me any alternate way to achieve offline speech recognition...

from pocketsphinx.pocketsphinx import *

r = sr.Recognizer()

decoder = Decoder(config)

decoder = decoder.decode_raw(open(AUDIO_FILE, 'rb'))

hypothesis = decoder.hyp()

for best, i in izip(decoder.nbest(), range(10)):
print best.hyp().best_score, best.hyp().hypstr

decoder.process_raw(buf, False, False)
else:

decoder.end_utt()

Hello @vipulsurya, are you already find the solution? If yes can you tell me how to fix that error

And btw, if we mix sphinx and speech recognition library , we can use it offline?

Thanks
