Answer 1

This error means that your command value is "NONE"
Make sure your take_command() functions returns what it is supposed to.

listener = sr.Recognizer()
assistant_name = 'Jarvis'
boss_name = 'Sai Charan'
def speak(text):
speaker = pyttsx3.init()
speaker.say(text)
print(text)
speaker.runAndWait()
def recognize_command():
with sr.Microphone() as source:
listener.adjust_for_ambient_noise(source, duration=1)
print('Listening...')
listener.pause_threshold = 1
audio = listener.listen(source)
try:
print("Recognizing...")
command = listener.recognize_google(audio)
print(f"User said: {command}\n")
except Exception as e:
speak('Unable to Recognize your voice , please repeat it boss')
pass
def start_up():
speak('Loading Requirements...')
speak('Activating Jarvis...')
print('(Loading...)')
sleep(3)
speak('Jarvis is Initialized...')
def wish_boss():
hour = int(datetime.datetime.now().hour)
if hour >= 0 and hour < 12

Answer 5

Thank you so much

Answer 6

After this task operator function

Answer 7

Where is take_command() function? its the one that likely causes the problem.

Answer 8

Take command is named as recognise command

Answer 9

Then in recognize_command() you do not return "command". But in Task_operator() you do commmand=recognize_command(), so your "command" variable ends up unassigned. Try returning your "command" variable in recognize_command() function.

Answer 14

Command must be a list, tuple, set, dictionary or string, in other words iterables in python
Notice that a function without a return sends None
