Which technology allows users to interact with AI using everyday language?

Conversational AI enables users to interact with artificial intelligence systems using natural, everyday language, making it accessible and user-friendly. It encompasses technologies such as chatbots and voice assistants that can understand, process, and respond to user queries in a human-like manner. This technology leverages natural language processing (NLP) to comprehend the context and intent behind user interactions, thereby facilitating seamless communication.

The other technologies listed, while related to AI, do not specifically focus on human interaction in natural language. Artificial Neural Networks (ANN) are computational models inspired by the human brain, used to recognize patterns and make predictions but do not pertain directly to conversational capabilities. Ethical AI refers to the framework of ensuring that artificial intelligence operates within moral boundaries, ensuring fairness and accountability, but it does not address interaction methods. Deep Learning is a subset of machine learning that employs neural networks with multiple layers to analyze complex data, which can be part of the technology behind conversational AI, yet it is not designed for user interaction itself.
