属性错误：找不到PyAudio；请检查安装...无法使用语音识别。

Question

我想制作一个基本的语音识别助手。当我运行代码时，它告诉我：

Traceback (most recent call last):
  File "C:\Users\Mo.haytham\AppData\Local\Programs\Python\Python37\lib\site-packages\speech_recognition\__init__.py", line 108, in get_pyaudio
    import pyaudio
ModuleNotFoundError: No module named 'pyaudio'

During handling of the above exception, another exception occurred:

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

我尝试使用pip install pyaudio安装，但出现了以下错误：

Answer 1

在终端中输入。

pip install pipwin

那么

pipwin install pyaudio

这将在 Python 3.8.5 中运行，我试图在最新版本中安装它，但不起作用。 - Saad Abbasi

Answer 2

如果您是Ubuntu 18.04用户，请按照以下步骤操作：

sudo apt-get install portaudio19-dev python-pyaudio

那么

pip install PyAudio

尝试在Ubuntu 22.04上使用命令sudo apt-get install portaudio19-dev python3-pyaudio。 - undefined

Answer 3

我也发现安装PyAudio可能会让一些终端用户很苦恼，甚至成为无法接受的问题，因为安装有困难。理论上，speech_recognition.Recognizer.listen() 可以从其他音频库（如sounddevice、soundcard或audiomath）获取输入，这些库通常更容易安装。幸运的是，虽然 speech_recognition 代码本身只提供 PyAudio 实现，但内部仅需要对 Microphone 的一些属性进行鸭式类型转换即可成功使用 listen() 方法。具体来说：

• source 必须是 speech_recognition.AudioSource 类的实例
• source.stream 在源处于活动状态时必须为非 None
• source.CHUNK 必须是每个块的样本数（整数）
• source.SAMPLE_RATE 必须是采样率
• source.SAMPLE_WIDTH 必须是每个样本的字节数
• source.stream.read(numberOfSamples) 必须返回原始单声道音频数据

这里是使用 audiomath 的鸭子类型解决方案：

import audiomath; audiomath.RequireAudiomathVersion( '1.12.0' )
import speech_recognition  # NB: python -m pip install SpeechRecognition

class DuckTypedMicrophone( speech_recognition.AudioSource ): # descent from AudioSource is required purely to pass an assertion in Recognizer.listen()
    def __init__( self, device=None, chunkSeconds=1024/44100.0 ):  # 1024 samples at 44100 Hz is about 23 ms
        self.recorder = None
        self.device = device
        self.chunkSeconds = chunkSeconds
    def __enter__( self ):
        self.nSamplesRead = 0
        self.recorder = audiomath.Recorder( audiomath.Sound( 5, nChannels=1 ), loop=True, device=self.device )
        # Attributes required by Recognizer.listen():
        self.CHUNK = audiomath.SecondsToSamples( self.chunkSeconds, self.recorder.fs, int )
        self.SAMPLE_RATE = int( self.recorder.fs )
        self.SAMPLE_WIDTH = self.recorder.sound.nbytes
        return self
    def __exit__( self, *blx ):
        self.recorder.Stop()
        self.recorder = None
    def read( self, nSamples ):
        sampleArray = self.recorder.ReadSamples( self.nSamplesRead, nSamples )
        self.nSamplesRead += nSamples
        return self.recorder.sound.dat2str( sampleArray )
    @property
    def stream( self ): # attribute must be present to pass an assertion in Recognizer.listen(), and its value must have a .read() method
        return self if self.recorder else None

if __name__ == '__main__':
    import speech_recognition as sr
    r = sr.Recognizer()
    with DuckTypedMicrophone() as source:
        print('\nSay something to the %s...' % source.__class__.__name__)
        audio = r.listen(source)
    print('Got it.')
    print('\nUnderstood: "%s"\n' % r.recognize_google(audio))

    if 0: # plot and/or play back captured audio
        s = audiomath.Sound(audio.get_wav_data(), fs=audio.sample_rate, nChannels=1)
        s.Play()
        s.Plot()

Answer 4

由于没有C++构建工具来安装pyaudio，您会遇到安装pyaudio的错误。

要安装Microsoft Visual C++ 14.0，请考虑使用此链接：https://dev59.com/uF0a5IYBdhLWcg3w48BP#49986365

然后，安装pyaudio。

如果您在Anaconda提示符上使用jupyter笔记本，则：

conda install pyaudio

如果您正在使用CMD使用Jupyter笔记本电脑，则在Jupyter单元格上，

import sys
!{sys.executable} -m pip install pyaudio

如果你正在cmd上运行Python文件，则：

pip3 install pyaudio #for python3

Answer 5

在 Mac M1 上安装 PyAudio 和 PortAudio 的步骤

python3 -m pip install --upgrade pip setuptools wheel
brew install portaudio --HEAD
python3 -m pip install pyaudio --global-option="build_ext" --global-option="-I/opt/homebrew/include" --global-option="-L/opt/homebrew/lib"

- ChrisDanger

Answer 6

看起来你缺少一些构建pyaudio所需的文件。

从你的错误日志中可以看出，

需要 Microsoft Visual C++ 14.0。请使用“Microsoft Visual C++ Build >Tools”获取它：https://visualstudio.microsoft.com/downloads/

你需要安装Microsoft Visual C++ Build Tools。

Answer 7

即使安装了pipwin，我仍然遇到问题，所以在安装PyAudio之前，请执行以下操作以找到解决方案

!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg

- yashraj sharma

Answer 8

适用于MacOS：

使用以下命令安装portaudio：

brew install portaudio

然后使用以下命令安装pyaudio：

pip install pyaudio

Answer 9

sudo apt-get install libportaudio-dev（首先尝试使用此命令） sudo apt-get install portaudio19-dev（如果不行，请使用此命令） 然后安装pyaudio（python -m pip install PyAudio）

Answer 10

针对您遇到的错误，提示需要下载C++构建工具，我也曾遇到过同样的问题。我尝试了下载Microsoft Visual Studio运行库，但并没有解决问题。后来我下载了带有Anaconda插件的PyCharm社区版，并下载了Anaconda，激活后使用conda的python.exe配置了一个conda解释器。然后我输入以下命令： conda install PyAudio 这样就成功安装了所有必要的组件。我建议您也可以尝试这种方法。
