I have installed speech recognition both on python3 and python on raspbian when I try to run my python file I get the following error

Seems like an issue with the installed module. Did you install it using pip? - Specas
your PYTHONPATH for portaudio if already installed? - Gang
portaudio16 and pip already installed - Ahamid17

If you read back through the Traceback error, essentially it's saying that on line 13, you successfully imported Speech from speech, but inside of that file it is trying to import a module called speech_recognition. Apparently, for reasons that I don't know, it cannot find that file.

Some Potential Fixes

  • Try reinstalling the module
  • Try reinstalling python on those devices
  • Try doing it on a different device
  • Try contacting the author of the module

Somebody else may be able to give some better advice as to fixes, seeing as I've never used this kind of module before, but this is my best bet.

Sorry for not being able to help more! Happy coding.
