我正在尝试制作基本的语音识别助手。当我运行代码时，它告诉我：

在终端类型
pip安装pipwin
然后
pipwin安装pyaudio
答案 2 :(得分：1)
由于没有C ++构建工具来安装pyaudio，因此安装pyaudio会出错。
要安装Mircosoft visual C ++ 14.0，请考虑以下链接Searching the tree
然后， 安装pyaudio。
如果您在anaconda提示符下使用jupyter笔记本，则
conda install pyaudio
如果您使用的是使用cmd的jupyter笔记本，然后在jupyter单元上
import sys
!{sys.executable} -m pip install pyaudio
如果您正在cmd上运行python文件，
pip3 install pyaudio #for python3
答案 3 :(得分：0)
看来您缺少一些构建pyaudio所需的文件。
从您的错误日志中，
需要Microsoft Visual C ++ 14.0。使用“ Microsoft Visual C ++ Build>工具”获取它：https://visualstudio.microsoft.com/downloads/
您需要安装Microsoft Visual C++ Build Tools

我还发现，由于安装困难，PyAudio的安装可能很痛苦，即使对于某些最终用户而言，也是一件麻烦事。原则上，speech_recognition.Recognizer.listen()没有理由不能从其他音频库（例如sounddevice或soundcard或audiomath）中获取输入，所有这些通常都更容易安装。幸运的是，尽管speech_recognition代码本身仅提供PyAudio实现，但在内部它只需要对Microphone的几个属性进行鸭式输入即可使其成功listen()。具体来说：
source必须是speech_recognition.AudioSource子类的实例source.stream必须不为None source.CHUNK必须是每个块的（整数）样本数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)必须返回原始的单通道音频数据这是使用audiomath的鸭子式解决方案：
import time, numpy, audiomath, speech_recognition
class DuckTypedMicrophone( speech_recognition.AudioSource ): # parent class required purely to pass assertion in Recognizer.listen
def __init__( self, device=None, chunkSeconds=1024/44100.0 ):
self.recorder = None
self.device = device
self.chunkSeconds = chunkSeconds
def __enter__( self ):
self.recorder = audiomath.Recorder( audiomath.Sound( 5, nchan=1 ), loop=True, device=self.device )
self.CHUNK = int( audiomath.SecondsToSamples( self.chunkSeconds, self.recorder.stream.fs ) )
self.SAMPLE_RATE = int( self.recorder.stream.fs )
self.SAMPLE_WIDTH = self.recorder.sound.bytes
self.nSamplesRead = 0
return self
def __exit__( self, *blx ):
self.recorder.Stop()
self.recorder = None
def read( self, nSamples ):
targetHead = audiomath.SamplesToSeconds( self.nSamplesRead + nSamples, self.SAMPLE_RATE )
while self.recorder.head < targetHead: time.sleep( 0.001 )
snd = self.recorder.sound
startSamples = self.nSamplesRead % snd.nSamples
chunk = snd.y[ startSamples : startSamples + nSamples, : ]
wrapped = nSamples - chunk.shape[ 0 ]
chunk = numpy.concatenate( ( chunk, snd.y[ :wrapped, : ] ), axis=audiomath.ACROSS_SAMPLES )
self.nSamplesRead += nSamples
return snd.dat2str( chunk )
@property
def stream( self ): # property required purely to pass assertion in Recognizer.listen
return self if self.recorder else None
if __name__ == '__main__':
import speech_recognition as sr
r = sr.Recognizer()
with DuckTypedMicrophone() as source: # replaces the PyAudio-dependent class sr.Microphone()
print('Say something to the %s...' % source.__class__.__name__)
audio = r.listen(source)
print('Got it.')
print('Understood: "%s"' % r.recognize_google(audio))
if 0: # plot and/or play back captured audio
import audiomath as am
s = audiomath.Sound(audio.get_wav_data(), fs=audio.sample_rate, nchan=1)
s.Play()
s.Plot()

即使在安装 pipwin 之后我也遇到了问题，所以我发现在安装 PyAudio 之前执行下面的解决方案
!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg
答案 6 :(得分：-1)
sudo apt-get install libportaudio-dev（首先尝试使用此命令） sudo apt-get install portaudio19-dev（代替使用此） 稍后安装pyaudio（python -m pip安装PyAudio）

对于表示下载C ++构建工具的错误，我也遇到了相同的错误。我下载了Microsoft Visual Studio运行时，但无法正常工作。然后，我下载了带有anaconda插件的pycharm社区版。我下载了anaconda，将其激活，然后使用conda的python.exe配置了conda解释器。然后输入以下内容： 康达安装PyAudio 而且它对我来说一切都很好。我建议这样做。
答案 8 :(得分：-2)
Python 2.7、3.4、3.5和3.6（32位和64位）都支持PyAudio。您可能必须安装上述任何python才能使PyAudio正常工作。
