cmu pocketphinx を使用して簡単な音声認識エンジンをコーディングしようとしていますが、decode_raw()関数に遭遇すると常にクラッシュします。PyPocketSphinx（pipでインストール）を使用して、Windows 7 64ビットでPython 2.7 32ビットを使用しています
これが私のコードです：
from pocketsphinx import Decoder
import sphinxbase
HMM="pocketsphinx-5prealpha-win32/model/en-us/en-us/"
LM="pocketsphinx-5prealpha-win32/model/en-us/en-us.lm.dmp"
DICT="pocketsphinx-5prealpha-win32/model/en-us/cmudict-en-us.dict"
config=Decoder.default_config()
config.set_string("-hmm",HMM)
config.set_string("-lm",LM)
config.set_string('-dict',DICT)
decoder=Decoder(config)
fh=open("output.wav",'rb')
fh.seek(44)
decoder.decode_raw(fh) #Crash
print decoder.get_hyp()
この問題を 1 週間以上解決しようとしましたが、まだ答えが見つかりません。
