Error:

UnboundLocalError: local variable 'command' referenced before assignment 

I feel that's pretty clear. You're using a variable (or at least referring to it) before you ever set it's value.

def myCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print(' I am ready for your next command')
        r.pause_threshold = 1
        r.adjust_for_ambient_noise(source, duration = 1)
        audio = r.listen(source)
    try:
        command = r.recognize_google(audio)
        print('You said: ' + command + '/n')
 
    except sr.UnknownValueError:
            assistant(myCommand())
    return command

You only set it inside a try/except block, so if there's an error in r.recognize_google(), it never has a value. Give it a default value so that doesn't happen.
