The technology used to enable voice-activated devices, such as smart speakers, is known as natural language processing (NLP) and voice recognition systems. These technologies allow devices to interpret and respond to spoken commands by converting audio signals into text and understanding the intent behind user queries. Integrating NLP with artificial intelligence enables devices to provide meaningful responses, execute tasks, and learn user preferences over time. This has created an interactive experience, enhancing the user-friendliness and functionality of voice-activated devices across various applications, from home assistants to customer service chatbots.
