5 years ago While you are configuring pyAudio for microphone voice input make some changes as i do in "/home/pi/Pi3RoadTest/recoMic/pocket_sphinx_listener.py"
p = pyaudio.PyAudio() stream = p.open(format=pyaudio.paInt16, channels=1, rate= 44000, input= True, frames_per_buffer=512)
And the other changing is when the read function of pyaudio is called in the continuous loop You need to change like this buffer = stream.read(512, False)
If you change both th lines in your code i hope it will work for you as it has worked for me you can adjust the frames_per_buffer from 512 to 1024 both works fine with 44000 and 48000 rate
hello I am on rpi3, os: raspbian I do everything in Sphinx On Pi3.txt everything was ok until I run "~/Pi3RoadTest/recoMic $ python mymain.py"
and here is my log:

I google the error but get nothing same as my error.even try to change the sample rate from 16000 to 8000,4000,800 and nothing changed!
thank you ali
