NLP vs NLG: Understanding the Core Technologies Behind AI Conversations

In the age of AI-driven communication, terms like NLP (Natural Language Processing) and NLG (Natural Language Generation) are frequently used. While they sound similar, they serve distinct purposes within conversational AI systems. Understanding the difference between NLP and NLG is essential for anyone looking to explore how machines are transforming human language interactions—be it through chatbots, voice assistants, or intelligent writing tools. In this blog, we break down the key concepts, core functionalities, and real-world applications of NLP and NLG to help you understand how they power today’s AI conversations. What is NLP (Natural Language Processing)? Natural Language Processing (NLP) is a field of artificial intelligence that focuses on enabling machines to understand, interpret, and respond to human language. NLP serves as the foundational technology that allows AI to "read" or make sense of text and speech in the way humans do. Key Tasks of NLP Include: Te...
