Create OpenAI API credentials\n2. Set up AWS S3 bucket with public read permissions\n3. Configure webhook path\n4. Test with POST request containing:\n - Audio file (binary)\n - Languages parameter (e.g., \"English, Spanish\")\n\n### Requirements\n- OpenAI API key (for Whisper and GPT-4)\n- AWS account with S3 access\n- S3 bucket for audio storage\n\n### How to customize\n- Change GPT model for different translation quality\n- Adjust voice settings in text-to-speech\n- Add language detection if source unknown\n- Implement file size limits\n- Add webhook authentication"
