【问题标题】:Running different commands with different words in PocketSphinx在 PocketSphinx 中使用不同的单词运行不同的命令
【发布时间】:2016-06-29 04:32:59
【问题描述】:

我已经找到了使用多个关键字激活 pocketsphinx 的方法,但我想根据所说的关键字运行不同的命令。当我说“Alexa”时,我已经让它连接到亚马逊的 Alexa 服务器,现在我想在我说“TV Off”和“TV On”时添加一个命令。

    【解决方案1】:

    最好是用python,像这样:

    import sys, os
    from pocketsphinx.pocketsphinx import *
    from sphinxbase.sphinxbase import *
    import pyaudio
    
    modeldir = "../../../model"
    
    # Create a decoder with certain model
    config = Decoder.default_config()
    config.set_string('-hmm', os.path.join(modeldir, 'en-us/en-us'))
    config.set_string('-dict', os.path.join(modeldir, 'en-us/cmudict-en-us.dict'))
    config.set_string('-kws', 'keyword.list')
    
    p = pyaudio.PyAudio()
    stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024)
    stream.start_stream()
    
    # Process audio chunk by chunk. On keyword detected perform action and restart search
    decoder = Decoder(config)
    decoder.start_utt()
    while True:
        buf = stream.read(1024)
        if buf:
             decoder.process_raw(buf, False, False)
        else:
             break
        if decoder.hyp() == "tv on":
            print ("Detected keyword tv on, turning on tv")
            os.system('beep')
            decoder.end_utt()
            decoder.start_utt()
        if decoder.hyp() == "tv off":
            print ("Detected keyword tv off, turning off tv")
            os.system('beep beep')
            decoder.end_utt()
            decoder.start_utt()
