Voice Assistant Project

Description

This project is a simple voice assistant application built using Python. It leverages speech recognition to understand voice commands and perform various tasks such as telling the time, opening a web browser, playing songs on YouTube, and running applications.

Functionalities

The voice assistant can perform the following tasks:

• Tell the current time when the user asks for it.
• Open a web browser (Google Chrome).
• Play a song on YouTube.
• Run an application specified by the user.
• Exit the program when the user commands it to stop.

Future Functionalities

Additional functionalities that can be added:

• Fetch and read the latest news headlines.
• Provide weather updates.
• Set reminders or alarms.
• Send emails or messages.
• Control smart home devices.
• Answer general knowledge questions using a web API.

The following Python libraries are required for this project:

• speech_recognition
• datetime
• subprocess
• pywhatkit
• pyttsx3
• webbrowser

Installation

1. Clone the repository to your local machine.

2. Install the required libraries using pip:

4. Speak your commands clearly when prompted.

Code Explanation

# Initialize the pyttsx3 engine
engine = pyttsx3.init()

# Set the voice property (index 1 for female voice, 0 for male voice)
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[1].id)  # You can change the index to 0 for a male voice

# Initialize the recognizer
recognizer = sr.Recognizer()

    engine.say(text)
    engine.runAndWait()

            subprocess.call(app)
