I am attempting to write a speech recognition program for the raspberry pi, however I am facing some issues using python's speech_recognition library.
From the error messages (posted below) I think the issue may be with the wrong sound card being accessed, however I am able to record with PyAudio (which I think the microphone class uses) as well as 'arecord'
Below is the code I am trying to run:
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
while True:
audio = r.listen(source)
try:
printf("You said " + r.recognize(audio))
except LookupError:
printf("Could not understand audio")
I have made some adjustments to which soundcard is used as default.
My "/etc/modprobe.d/alsa-base.conf" file is untouched and standard.
I have created a file in /home/pi under the name ".asoundrc" which contains:
pcm.!default {
type asym
playback.pcm "hw:0,0"
capture.pcm "hw:1,0"
}
This allows for recording from the USB microphone and playback through the on-board headphone jack port.
Below is the error message I received when trying to run the python script:

Thanks for the response, I checked that reference and I definitely think that was part of the problem. However I have found that my microphone is on index 2 and changed my code to: with sr.Microphone(2) as source: and with sr.Microphone(device_index = 2) as source: But to no avail, I am hit with the same errors :

I also get an extra few error messages at the bottom regarding the maxchannels value being incorrect

Thanks for the response, I checked that reference and I definitely think that was part of the problem. However I have found that my microphone is on index 2 and changed my code to: with sr.Microphone(2) as source: and with sr.Microphone(device_index = 2) as source: But to no avail, I am hit with the same errors :

I also get an extra few error messages at the bottom regarding the maxchannels value being incorrect

Per that Raspberry ALSA sound output / input slave CL mentions, those "errors" are just garbage dumped by PortAudio.
I think your real error is about the jack server not running.
