找不到 PyAudio，请检查安装

我是语音识别新手，正在尝试使用 Google Speech API 构建语音转文本程序。我使用以下链接中提供的教程和其中的命令来安装依赖项。教程：https://pythonspot.com/en/speech-recognition-using-google-speech-api/

命令：

git clone http://people.csail.mit.edu/hubert/git/pyaudio.git
cd pyaudio
sudo python setup.py install
sudo apt-get installl libportaudio-dev
sudo apt-get install python-dev
sudo apt-get install libportaudio0 libportaudio2 libportaudiocpp0 portaudio19-dev
sudo pip3 install SpeechRecognition

然后我尝试在 spyder 中运行这个虚拟脚本，看看它是否正常工作，

import speech_recognition as sr

# Record Audio
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

# Speech recognition using Google Speech Recognition
try:
# for testing purposes, we're just using the default API key
# to use another API key, use `r.recognize_google(audio, 
#key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
# instead of `r.recognize_google(audio)`
    print("You said: " + r.recognize_google(audio))
except sr.UnknownValueError:
    print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
    print("Could not request results from Google Speech Recognition service; {0}".format(e))

`

现在，当我运行该脚本时，我不断收到此错误：

Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):

File "<ipython-input-1-2b39d94ceb5b>", line 1, in <module>

raise AttributeError("Could not find PyAudio; check installation")

AttributeError: Could not find PyAudio; check installation

我已经在互联网上搜索过是否可以解决这个问题，但似乎没有找到任何可行的方法，这是我第一次使用任何类型的语音识别。

如果您能对此问题提供任何帮助，或者对如何学习和提高语音识别能力提出任何建议，我们将不胜感激。

这条消息告诉你找不到 PyAudio；检查安装

您的“教程”中的这个命令列表是错误的，您首先安装库，然后编译 python 模块：

git clone http://people.csail.mit.edu/hubert/git/pyaudio.git
cd pyaudio
sudo python setup.py install
sudo apt-get installl libportaudio-dev
sudo apt-get install python-dev
sudo apt-get install libportaudio0 libportaudio2 libportaudiocpp0 portaudio19-dev
sudo pip3 install SpeechRecognition

正确的顺序是：

sudo apt-get install libportaudio-dev
sudo apt-get install python-dev
sudo apt-get install libportaudio0 libportaudio2 libportaudiocpp0 portaudio19-dev
git clone http://people.csail.mit.edu/hubert/git/pyaudio.git
cd pyaudio
sudo python setup.py install
sudo pip3 install SpeechRecognition

该错误主要是由于安装 pyaudio 的步骤中的错误引起的sudo python setup.py install。您需要重复此步骤。您需要先分析并报告此步骤中发生的错误，然后再继续下一步。
