Popular examples include Amazon Alexa, Google Assistant, and Apple Siri. These assistants can control smart home devices, play music, set reminders, and provide information, making daily tasks more convenient. The technology behind voice-activated assistants relies on natural language processing and machine learning to understand and respond to user queries. As they continue to evolve, these assistants are becoming more integrated into our lives, enhancing productivity and accessibility for users of all ages.
