The technology that enables automated responses in customer service is primarily based on chatbots or virtual assistants. These systems use **natural language processing** (NLP) and **machine learning** to understand and respond to customer inquiries without human intervention. Chatbots can handle a variety of tasks, including answering FAQs, processing orders, or facilitating bookings. They enhance customer engagement by providing instant responses, improving overall customer satisfaction, and reducing the workload on human agents, allowing them to focus on more complex issues.
