Conversational Telegram Bot with GPT-4o for Text & Voice

This n8n workflow creates a sophisticated Telegram chatbot powered by GPT-4o that handles both text messages and voice notes. Upon receiving a message via the Telegram Trigger, it checks if it's voice input and transcribes it using OpenAI's speech-to-text service. The transcribed or direct text is then fed into an AI Agent for intelligent, context-aware response generation. A typing indicator is sent to simulate human-like processing, enhancing user experience.

Key benefits include multi-modal support for versatile communication, real-time feedback for engaging conversations, and easy integration with n8n's no-code environment. It saves time on manual responses and scales for high-volume interactions. Ideal for HRMS applications like employee queries on policies, leave requests, or onboarding support.

Use cases span HR management (e.g., instant answers to payroll FAQs, voice-based feedback collection), customer support, or internal team bots. Setup is straightforward: create a bot via @BotFather, configure Telegram and OpenAI credentials, import the workflow, and set the webhook URL for production deployment.
