I am trying to build a voice assistant. I am facing a problem with the playsound library. Please view my code snippet.
def respond(output):
    """
    function to respond to user questions
    """
    num=0
    print(output)
    num += 1
    response=gTTS(text=output, lang='en')
    file = str(num)+".mp3"
    response.save(file)
    play(file, True) #playsound import playsound as play
if __name__=='__main__':
    respond("Hi! I am Zoya, your personal assistant")
My audio file is getting generated, however at the line play(file,True) it is throwing the following error.
---------------------------------------------------------------------------

      5         respond("How can I help you?")

    362             cmd = popenargs[0]

CalledProcessError: Command '['/usr/bin/python3', '/usr/local/lib/python3.7/dist-packages/playsound.py', '1.mp3']' returned non-zero exit status 1.
How do I resolve the issue? I would also like to mention that I am working on google colab.
