Conversational AI refers to technologies that enable machines to understand and respond to human language in a natural way. This includes chatbots and virtual assistants, which can engage in dialogue with users, answer questions, and provide information. These systems use techniques from fields like natural language processing and machine learning to interpret and generate text or speech. The goal of conversational AI is to create seamless interactions between humans and machines, making it easier for users to access services or information. Examples include Siri, Alexa, and customer service bots on websites, which help improve user experience and efficiency in communication.
