Natural Language Processing
AI that understands and generates human language — the foundation of chatbots and voice bots.
Natural Language Processing (NLP) is the field of AI focused on human language: understanding what a person means (even with typos, slang or Hinglish), extracting information, and generating natural replies. NLP is what lets a WhatsApp chatbot grasp "mera order kahan hai" or a voice bot understand a spoken request and respond appropriately.
