Conversational AI is a type of artificial intelligence (AI) that can simulate human conversation. It is made possible by natural language processing (NLP), a field of AI that allows computers to understand and process human language. NLP is used to analyze the meaning of text and speech, and to generate responses that are appropriate and relevant to the conversation.

Conversational AI systems are trained on large amounts of data such as text and speech. This data is used to teach the system how to understand and process human language. The system then uses this knowledge to interact with humans in a natural way. It’s constantly learning from its interactions and improving its response quality over time.
