Natural Language Generation (NLG) is a technology that automatically produces human-readable text or speech from structured and unstructured data. While its counterpart, Natural Language Understanding (NLU), focuses on comprehension, NLG transforms data into meaningful narratives. It is widely applied in chatbots, voice assistants, automated reports, and other business contexts.

Natural Language Understanding (NLU) is a critical area of Natural Language Processing (NLP) that enables computers to accurately interpret human language in context. Beyond recognizing individual words, NLU can grasp user intent and emotions, making it applicable to chatbots, voice assistants, sentiment analysis, and more. This enhances conversational AI and data-driven decision-making.
