Welcome to my Wikipedia Podcast Telegram Bot Workflow!
This workflow creates an intelligent Telegram bot that transforms Wikipedia articles into engaging 5-minute podcast episodes using natural language queries and voice messages.

What this workflow does
This workflow processes incoming Telegram messages (text or voice, e.g. "Berlin") and generates professional podcast content about any Wikipedia topic (e.g. "Berlin", "Shakespeare", etc.). The AI agent researches the requested subject, creates a structured podcast script, and delivers it as high-quality audio directly through Telegram.

Key Features:
Voice message support (speech-to-text and text-to-speech)
Wikipedia research integration for accurate content
Professional podcast structure (intro, main content, outro)
Natural-sounding AI voice synthesis
Conversational and educational tone optimized for audio consumption

This workflow has the following sequence:

Telegram Trigger - Receives incoming messages (text or voice) from users via Telegram bot
Text or Voice Switch - Routes the message based on input type (text message vs. voice message)
Voice Message Processing (if voice input):
Retrieval of voice file from Telegram
Transcription of voice message to text using OpenAI Whisper
Text Message Preparation (if text input) - Prepares the text message for the AI agent
Wikipedia Podcast Agent - Core AI agent that:
Researches the requested topic using Wikipedia tool
Creates a professional 5-minute podcast script (600-750 words)
Follows structured format: intro, main content, outro
Uses conversational, accessible, and enthusiastic tone
ElevenLabs Text to Speech - Converts the podcast script into natural-sounding audio using AI voice synthesis
Send Voice Response - Delivers the generated podcast audio back to the user via Telegram
