Question

我正在使用pocketsphinx将语音编程到文本解码器。

程序运行正常但当我尝试进行关键字定位时会发生错误。

当我试图获得hypstr时，问题似乎出现在最后的印刷品中。

我收到错误。

AttributeError: 'NoneType' object has no attribute 'hypstr'

我该如何解决？

# Decoder config
config = Decoder.default_config()
config.set_string('-hmm', os.path.join(MODEL_DIR, 'es/es'))
config.set_string('-dict', os.path.join(MODEL_DIR, 'voxforge_es_sphinx.dic'))
config.set_string('-lm', os.path.join(MODEL_DIR, 'es-20k.lm'))
#config.set_string('-keyphrase', 'escucha')
#config.set_float('-kws_threshold', 1e+20)
#config.set_string('-jsgf', GRAMMAR)
decoder = Decoder(config)
#decoder.set_jsgf_file('grammar', GRAMMAR)
decoder.set_keyphrase('keyphrase', 'escucha')
decoder.set_search('keyphrase')

# Pyaudio config
p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024)
stream.start_stream()

in_speech_bf = False
decoder.start_utt()
while True:
    buf = stream.read(1024, exception_on_overflow = False)
    if buf:
        decoder.process_raw(buf, False, False)
        if decoder.get_in_speech() != in_speech_bf:
            in_speech_bf = decoder.get_in_speech()
            if not in_speech_bf:
                decoder.end_utt()

                #Print hypothesis
                print 'Result:', decoder.hyp().hypstr

                if decoder.get_search() == 'keyphrase':
                    decoder.set_search('lm')
                else:
                    decoder.set_search('keyphrase')

                decoder.start_utt()
    else:
        break
decoder.end_utt()

Pocketsphinx Decoder.hyp不返回假设对象
