PDF To Audio

Convert your PDF documents into audio files effortlessly with PDF to Audio Converter. This Python script harnesses the power of Optical Character Recognition (OCR) and Google's Text-to-Speech (gTTS) service to transform written content into spoken words. Ideal for accessibility, auditory learning, or enjoying documents on-the-go.

🌟 Features

  • PDF Text Extraction: Utilizes pdfplumber for precise text extraction.
  • OCR Capability: Integrates pytesseract for handling image-based PDFs.
  • Text-to-Speech: Leverages Google's gTTS API for high-quality audio output.
  • Parallel Processing: Option for faster processing of multiple documents.
  • Rate Limit Management: Smart retry logic with exponential backoff.
  • Flexible CLI: Command-line interface for customizable configurations.

📋 Installation

Get started with these simple steps:

Prerequisites

  • Python 3.x
  • Required packages: pdfplumber, pytesseract, Pillow, gtts

Install Python Packages
