VoiceFlow: Advanced Telegram Bot Source Code for Audio Transcription and PDF Summarization

Unlock the power of automation with VoiceFlow, a feature-rich Telegram bot designed for audio transcription, PDF summarization, subscription management, and user support. This Python-based source code is perfect for developers, entrepreneurs, or businesses looking to deploy a customizable, monetizable bot on Telegram. Built with modern libraries like Telethon and aiogram, VoiceFlow is a robust solution for processing media, handling payments, and engaging users.

What You Get

• Complete Source Code: A well-structured Python codebase with modules for handling audio, subscriptions, support tickets, and more.
• Database Schema: SQLite-based database for managing users, transcriptions, payments, logs, and support tickets.
• Documentation: Basic setup instructions to get the bot running on your server.
• Dependencies List: All required Python libraries and external tools (e.g., ffmpeg for audio processing).
• Open-Source Libraries: Built with Telethon, aiogram, aiohttp, pydub, and reportlab, ensuring no proprietary licensing costs.

Key Functional Capabilities

1. Audio Transcription:
   • Converts audio files (MP3, OGG, WAV, M4A, etc.) to text using the Whisper API.
   • Supports URL-based audio/video downloading (e.g., YouTube) with real-time progress updates.
   • Handles media groups for batch processing of multiple files.
   • Exports transcriptions as PDF files with Cyrillic support using DejaVuSans font.
2. PDF Summarization:
   • Uploads PDF files to a backend API for detailed or brief summarization.
   • Asynchronous processing with status updates to keep users informed.
   • Integrates with a custom API for file uploads and result retrieval.
3. Subscription and Payment System:
   • Supports free and paid tiers (basic and pro) with time-based and file-count limits.
   • Integrates with Telegram Stars for seamless in-app payments.
   • Automatically manages subscription statuses, renewals, and expirations.
   • Notifies users when subscriptions are about to expire.
4. Support Ticket System:
   • Allows users to create support tickets with a simple interface.
   • Admin panel for managing and responding to tickets.
   • Notifies users of admin replies with inline buttons for easy navigation.
5. Achievement System:
   • Gamifies user engagement by rewarding transcription milestones (e.g., 5, 20, 50, 100+ hours).
   • Updates user achievement levels in the database and sends celebratory messages.
6. Robust Error Handling and Logging:
   • Comprehensive logging to a file (bot.log) for debugging and monitoring.
   • Error handling for API calls, file conversions, and database operations.
   • Semaphore-based API request management to prevent overload.
7. Scalable Architecture:
   • Modular design with separate files for handlers, database models, support, and API interactions.
   • Asynchronous operations using asyncio and aiohttp for high performance.
   • Easily extensible for additional features or API integrations.

Technical Details

• Programming Language: Python 3.8+
• Main Libraries:
  • Telethon and aiogram for Telegram API interactions
  • aiohttp for asynchronous HTTP requests
  • pydub and ffmpeg for audio processing
  • reportlab for PDF generation
  • sqlite3 for database management
• Database: SQLite (users.db) with tables for users, payments, transcriptions, logs, and support tickets
• External Dependencies: ffmpeg (for audio validation and conversion), Whisper API (for transcription), custom backend API (for PDF summarization)
• Configuration: Requires API keys for Whisper API and the custom backend API, plus a Telegram bot token.

Setup Requirements

To deploy VoiceFlow, you'll need:

• A server or local machine with Python 3.8+ and ffmpeg installed.
• A Telegram bot token (obtained via BotFather).
• API keys for the Whisper API and the custom backend API (replace placeholders in config.py).
• A SQLite database (automatically created on first run).
• Basic knowledge of Python and Telegram bot development for customization.

Setup Instructions

1. Clone the source code to your server.
2. Install dependencies: pip install telethon aiogram aiohttp pydub reportlab.
3. Install ffmpeg: sudo apt-get install ffmpeg (Linux) or equivalent for your OS.
4. Configure config.py with your Telegram bot token, Whisper API key, and backend API credentials.
5. Run main.py to start the Telethon-based bot and aiobot.py for aiogram-based payment handling.
6. Deploy on a server (e.g., Heroku, AWS, or a VPS) for 24/7 operation.
