语音识别python3.4与pocketsphinx

Question

我只是按照这个>> steps <<并运作良好，

现在，我如何开始使用python？我试过这段代码：

import speech_recognition as sr

# obtain audio from the microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

# recognize speech using Sphinx
try:
    print("Sphinx thinks you said " + r.recognize_sphinx(audio))
except sr.UnknownValueError:
    print("Sphinx could not understand audio")
except sr.RequestError as e:
    print("Sphinx error; {0}".format(e))

并得到一个错误：

Sphinx error; missing PocketSphinx module: ensure that PocketSphinx is set up correctly.

speech_recognition已经安装，但我不确定pocketphinx和sphinxbase。我所做的一切：https://cmusphinx.github.io/wiki/tutorialpocketsphinx/

你需要pip install PocketSphinx，它取决于二进制SWIG包。对于Windows，SWIG指令位于this SO answer中。

对于OSX，还有其他要求：

$ brew install cmu-pocketsphinx
$ brew install portaudio
$ brew install swig
$ pip install PocketSphinx
