import speech_recognition as sr
import webbrowser
import musiclibrary
import requests

news_api = "YOUR_NEWS_API_KEY"
choice = True
Recognizer = sr.Recognizer()
Engine = pyttsx3.init()
Engine.setProperty('rate', 150)

def Speak(Text):
    Engine.say(Text)
    Engine.runAndWait()

def ProcessCommand(command):
    if "open google" in command.lower():
        webbrowser.open("https://google.com")
    elif "open facebook" in command.lower():
        webbrowser.open("https://facebook.com")
    elif "open youtube" in command.lower():
        webbrowser.open("https://youtube.com")
    elif "open linkedin" in command.lower():
        webbrowser.open("https://linkedin.com")
    elif "open instagram" in command.lower():
        webbrowser.open("https://instagram.com")
    elif "open monkeytype" in command.lower():
        webbrowser.open("https://monkeytype.com")
    elif "open wikipedia" in command.lower():
        webbrowser.open("https://wikipedia.org")
    elif command.lower().startswith("play"):
        song = command.lower().split(" ")[1]
        link = musiclibrary.music[song]
        Speak("Playing your song")
        webbrowser.open(link)
    elif "bulletin" or "bullet" in command.lower():
        r = requests.get(f"https://api.thenewsapi.com/v1/news/all?api_token={news_api}&language=en&limit=3")
        if r.status_code == 200:
            Data = r.json()
            Articles = Data.get('data', [])
            for Article in Articles[:5]:
                title = Article.get("title", "No title available")
                Speak(f"News update: {title}")
                print(f"News update: {title}")
        else:
            Speak("Sorry, I couldn't fetch the news right now.")
    else:
        webbrowser.open(command)

if __name__ == "__main__":
    Speak("Initializing Jarvis...")
    while choice:
        r = sr.Recognizer()
        try:
            with sr.Microphone() as Source:
                print("Listening...")
                Audio = r.listen(Source, timeout=2, phrase_time_limit=2)
                print("Recognizing...")
                Command = r.recognize_google(Audio)
                print(Command)
            if Command.lower() == "jarvis":
                print("Yeah...")
                Speak("Yeah")
                with sr.Microphone() as source:
                    Audio = r.listen(source)
                    Command = r.recognize_google(Audio)
                    ProcessCommand(Command)
        except sr.UnknownValueError:
            print("Unable to listen please try again...")
        except Exception as e:
            print(f"Error: {e}")

Challenges Faced & Future Improvements

• Speech Recognition Accuracy: Background noise can sometimes affect recognition accuracy. Adding noise reduction techniques can help.
• Adding More Functionalities: Features like setting reminders, sending emails, and home automation can be integrated.
• Better Music Integration: Instead of fetching from a predefined list, using APIs like Spotify's would enhance the user experience.
  

Conclusion

Developing a voice-activated AI assistant like Jarvis is an exciting way to explore AI, automation, and Python libraries. This project can be expanded with more intelligent features, making it a useful personal assistant.
