Conversational interfaces are systems that allow users to interact with technology using natural language, either through text or voice. These interfaces can be found in applications like chatbots and virtual assistants, such as Siri or Alexa. They aim to make communication with devices more intuitive and user-friendly, mimicking human conversation. These interfaces utilize techniques from artificial intelligence and natural language processing to understand and respond to user queries. By enabling a more natural form of interaction, conversational interfaces enhance user experience and accessibility, making it easier for people to access information and services without needing specialized knowledge.
