Trying to make assistant but facing speed problem

My program is working perfectly fine but I am having speed problems. It takes too long to respond and give results. After 2,3 runs it takes more time than before. Also additionally it takes lots of time to start. What are the ways to speed up of program? I am new in this field.

# Imported speech recognition as sr, pyttsx3, pywhatkit, datetime, pyjokes, os
listener = sr.Recognizer()
engine = pyttsx3.init()


def talk(text):
        engine.say(text)
        engine.runAndWait()


talk('Hello what can i do for you')


def take_command():
        try:
            with sr.Microphone() as source:
                print("Listening...")
                voice = listener.listen(source)
                command = listener.recognize_google(voice)
                command = command.lower()
                if "jarvis" in command:
                    command = command.replace('jarvis', '')
                    return command
                else:
                    talk("I cannot continue until you say jarvis")
                    take_command()
