Smart assistants like Siri and Alexa rely on artificial intelligence (AI) and natural language processing (NLP) to understand and respond to user commands. These systems continuously learn and adapt based on user interactions to improve their accuracy and effectiveness. By integrating with various smart devices, smart assistants can control home automation, provide information, and execute tasks using voice commands. The underlying technology involves complex algorithms that process spoken language, enabling users to engage with their devices intuitively. This innovation enhances convenience and accessibility in everyday tasks.
