HR & IT Helpdesk Chatbot with Audio Transcription

This n8n workflow creates an intelligent HR & IT helpdesk chatbot that supports both text and audio inputs from employees on platforms like WhatsApp or Telegram. Audio messages are automatically transcribed using services like Whisper or Google Cloud Speech-to-Text, converting them into text for seamless processing alongside direct text queries.

The core functionality involves generating embeddings from the query text via OpenAI, performing semantic searches in a vector database (e.g., Supabase or Qdrant) stocked with internal HR/IT documentation, and retrieving relevant info to craft concise, helpful responses. This RAG (Retrieval-Augmented Generation) approach ensures accurate, context-aware answers without hallucinations.

Benefits include reduced support ticket volume, 24/7 availability, hands-free querying for employees, and easy scalability. Ideal for companies seeking efficient internal knowledge management, it saves time on routine queries and integrates effortlessly with existing docs.

Use cases: Employee onboarding Q&A, IT troubleshooting, policy inquiries, remote worker support. Setup takes 20-25 minutes with prerequisites like API keys and doc ingestion.
