Dexter AI Assistant

Dexter AI Assistant is a Python-based virtual assistant designed to respond to voice commands, perform various tasks, and provide information. Inspired by popular assistants like Siri and Alexa, Dexter aims to deliver a user-friendly and efficient experience.

Features

• Voice Commands: Dexter can open applications, browse websites, play music, fetch news, and more through voice commands.
• Text-to-Speech: Uses pyttsx3 for converting text responses to speech.
• Speech Recognition: Uses speech_recognition to process and understand user commands.
• API Integration: Integrates with the NewsAPI to fetch the latest news headlines.
• Custom Responses: Uses OpenAI's GPT-3.5-turbo to generate responses for unrecognized commands.

What did I Learn?

• API Integration: Learned how to integrate and fetch data from external APIs.
• Environment Variables: Utilized environment variables to securely manage API keys and other sensitive information using the dotenv library.
• Libraries Used:
  • speech_recognition: For capturing and recognizing speech.
  • pyttsx3: For converting text to speech.
  • webbrowser: For opening websites.
  • requests: For making HTTP requests to APIs.
  • dotenv: For managing environment variables.
  • OpenAI: For generating AI responses.

Ongoing Improvements

• Web Scraping via Voice Commands: Working on the ability to scrape data from websites based on voice commands.
• Enhanced Voice Recognition: Improving the speed and accuracy of voice recognition to reduce latency and increase responsiveness.
• Setting Alarms: Adding functionality to set alarms and reminders through voice commands.
