How can I make a wake word in my code :(

[3yalzayed]

How can I put the wake word I tried many time

The code:

import libers

import speech_recognition as sr # recognise speech
import playsound # to play an audio file
from gtts import gTTS # google text to speech
import random
from time import ctime # get time details
import webbrowser # open browser
import yfinance as yf # to fetch financial data
import ssl
import certifi
import time
import os # to remove created audio files

class person:
name = ''
def setName(self, name):
self.name = name

def to listening 1

def there_exists(terms):
for term in terms:
if term in voice_data:
return True

def to listening 2

r = sr.Recognizer() # initialise a recogniser

listen for audio and convert it to text:

def record_audio(ask=False):
with sr.Microphone() as source: # microphone as source
if ask:
speak(ask)
audio = r.listen(source) # listen for the audio via source
voice_data = ''
try:
voice_data = r.recognize_google(audio) # convert audio to text
except sr.UnknownValueError: # error: recognizer does not understand
speak('Can you repeat')
except sr.RequestError:
speak('Sorry, the service is down') # error: recognizer is not connected
print(f">> {voice_data.lower()}") # print what user said
return voice_data.lower()

get string and make a audio file to be played and choose the lang

def speak(audio_string):
tts = gTTS(text=audio_string, lang='en') # text to speech(voice)
r = random.randint(1,20000000)
audio_file = 'audio' + str(r) + '.mp3'
tts.save(audio_file) # save as mp3
playsound.playsound(audio_file) # play the audio file
print(f"kiri: {audio_string}") # print what app said
os.remove(audio_file) # remove audio file

wake = ["welcome", "hey sara"]

respond for listening 1

def respond(voice_data):

# 1: greeting
if there_exists(['hey','hi','hello']):
    greetings = [f"hey, how can I help you {person_obj.name}", f"hey, what's up? {person_obj.name}", f"I'm listening {person_obj.name}", f"how can I help you? {person_obj.name}", f"hello {person_obj.name}"]
    greet = greetings[random.randint(0,len(greetings)-1)]
    speak(greet)

# 2: name
if there_exists(["what is your name","what's your name","tell me your name"]):
    if person_obj.name:
        speak("my name is sara")
    else:
        speak("my name is sara. what's your name?")

if there_exists(["my name is"]):
    person_name = voice_data.split("is")[-1].strip()
    speak(f"okay, i will remember that {person_name}")
    person_obj.setName(person_name) # remember name in person object

# 3: greeting
if there_exists(["how are you","how are you doing"]):
    speak(f"I'm very well, thanks for asking {person_obj.name}")

# 4: time
if there_exists(["what's the time","tell me the time","what time is it"]):
    time = ctime().split(" ")[3].split(":")[0:2]
    if time[0] == "00":
        hours = '12'
    else:
        hours = time[0]
    minutes = time[1]
    time = f'{hours} {minutes}'
    speak(time)

# 5: search google
if there_exists(["search for"]) and 'youtube' not in voice_data:
    search_term = voice_data.split("for")[-1]
    url = f"https://google.com/search?q={search_term}"
    webbrowser.get().open(url)
    speak(f'Here is what I found for {search_term} on google')

# 6: search youtube
if there_exists(["youtube"]):
    search_term = voice_data.split("for")[-1]
    url = f"https://www.youtube.com/results?search_query={search_term}"
    webbrowser.get().open(url)
    speak(f'Here is what I found for {search_term} on youtube')

# 7: get stock price
if there_exists(["price of"]):
    search_term = voice_data.lower().split(" of ")[-1].strip() #strip removes whitespace after/before a term in string
    stocks = {
        "apple":"AAPL",
        "microsoft":"MSFT",
        "facebook":"FB",
        "tesla":"TSLA",
        "bitcoin":"BTC-USD"
    }
    try:
        stock = stocks[search_term]
        stock = yf.Ticker(stock)
        price = stock.info["regularMarketPrice"]

        speak(f'price of {search_term} is {price} {stock.info["currency"]} {person_obj.name}')
    except:
        speak('oops, something went wrong')

# 8: to stop
if there_exists(["exit", "quit", "goodbye"]):
    speak("going offline")
    exit()

# 9: thank you responed
if there_exists(["thank you","thanks","you are the best"]):
        speak(" welcome sir ")

time.sleep(0.5)

person_obj = person()
while(1):
voice_data = record_audio() # get the voice input
respond(voice_data) # respond
