Pyttsx3 runtime error in VScode running Mac OS Sonoma

Question

I wrote an automation code in VScode for Mac OS.

import webbrowser
import speech_recognition as sr
import pyttsx3

# Function to listen to the my voice input
def listen(language="en-IN"):
    recognizer = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        recognizer.adjust_for_ambient_noise(source)
        audio = recognizer.listen(source)

    try:
        print("Recognizing...")
        # Recognize speech based on the selected language
        if language == "en-IN":
            query = recognizer.recognize_google(audio, language="en-IN")
        else:
            query = recognizer.recognize_google(audio, language="hi-IN")
        
        print(f"You said: {query}")
        return query.lower()
    except sr.UnknownValueError:
        print("Sorry, I didn't catch that. Can you repeat?")
        return ""
    except sr.RequestError:
        print("Sorry, there was an error processing the request.")
        return ""

# Function to convert text to speech
def speak(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()

if __name__ == "__main__":
    # Initialize the assistant and prompt for the first command
    speak("Hello! I'm friday.How can I help you?")
    language = "en-IN"  # Start with English

    # Continuously listen for commands and respond accordingly
    while True:
        command = listen(language)

        if "switch language" in command:
            # Toggle between English and Hindi
            if language == "en-IN":
                language = "hi-IN"
                speak("Switching to Hindi.")
            else:
                language = "en-IN"
                speak("Switching to English.")

        elif "open youtube" in command:
            # Open YouTube in a web browser
            speak("Opening YouTube...")
            webbrowser.open("https://www.youtube.com")
            
        elif "bye" in command:
            # Say goodbye and exit the loop
            speak("Goodbye!")
            break
        
        else:
            # Request for a command repetition if not understood
            speak("I didn't understand that command. Can you please repeat?")

** But when I run the program this error pops up:**

Traceback (most recent call last):

**How can I fix this?is this just an OS issue or is there an error in my code as I am very new to this field?

This looks like an issue being discussed in github.

You can try to install package py3-tts 3.5 according to their discussing by command pip install py3-tts
