portaudio installation on windows 10

[nima]

Hi everyone!

I'm new to python but already have learned about speech recognition. I want to use pyAudio class but the problem is when I'm calling it in a python file the console returns the message " Please build and install the PortAudio Python bindings first. "ow

please help me how to fix this problem . I've searched in sites but didn't find the answer.
thank you.

you should be able to install pyaudio with pip:

pip install pyaudio

# for python 3 may need to use
pip3 install pyaudio

For 3.7 it try to compile,for 3.6 it's get wheel as it should.
For 3.7 use wheel at Gohlke.

# Check pip,the newest is 18.1(python -m pip install --upgrade pip setuptools wheel)
C:\
λ pip -V
pip 18.1 from c:\python37\lib\site-packages\pip (python 3.7)

# Install the wheel(.whl) file,64-bit Python use amd64.whl
C:\
λ pip install PyAudio-0.2.11-cp37-cp37m-win32.whl
Processing c:\pyaudio-0.2.11-cp37-cp37m-win32.whl
Installing collected packages: PyAudio
Successfully installed PyAudio-0.2.11

If pip don't work look at Python 3.6/3.7 and pip installation under Windows.

The wheel is already build link.

pip will fetch and install PyAudio wheels (prepackaged binaries).
These binaries include PortAudio v19 v190600_20161030, built with MinGW. They support only the Windows MME API

So test:

>>> import pyaudio
>>> 
>>> pyaudio.__version__
'0.2.11'

Testing there example script:
py_au.py:

"""PyAudio Example: Play a WAVE file."""

import pyaudio
import wave
import sys

CHUNK = 1024

if len(sys.argv) < 2:
    print("Plays a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
    sys.exit(-1)

wf = wave.open(sys.argv[1], 'rb')

p = pyaudio.PyAudio()

stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

data = wf.readframes(CHUNK)

while data != '':
    stream.write(data)
    data = wf.readframes(CHUNK)

stream.stop_stream()
stream.close()

p.terminate()

It's a command line script so from cmd or cmder.
