PDF to Audiobook Converter

This is a web application that converts PDF files into audio files, creating a personalized audiobook experience. Users can upload a PDF, choose a text-to-speech (TTS) engine (offline or online), and generate an audio version of the document. This application supports both offline (using pyttsx3) and online (using Google TTS - gTTS) TTS engines with multiple language options.

• TTS Engine Choice: Choose between offline (pyttsx3) and online (Google TTS - gTTS) TTS engines.
• Voice and Language Selection: Customize the narration by choosing different voices or language codes.
• Responsive UI: Designed with Bootstrap for a modern and user-friendly interface.

Technologies Used

• Python (for backend processing of PDF and TTS conversion)
• Flask (for handling requests and routing)
