Python Forum

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.

thank you for answering
my problem now is not installing pyaudio library it's now "building and installing the PortAudio Python bindings"

The wheel is already build link.

Quote: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.

E:\div_code\new
λ python py_au.py Alarm.wav
