Conversational AI refers to technologies that enable machines to engage in human-like dialogue using natural language processing and machine learning. It powers virtual assistants, chatbots, and voice applications that understand, interpret, and respond to user inputs. Conversational AI systems can handle customer service, schedule appointments, answer FAQs, and even manage transactions across digital platforms. By continuously learning from interactions, conversational AI improves over time, offering personalized and context-aware experiences. It supports multiple languages and can be deployed across messaging apps, websites, and IoT devices. As businesses seek automation and user-centric services, conversational AI plays a pivotal role in enhancing communication efficiency.
