The technology that powers smart assistants like Siri and Alexa is primarily known as artificial intelligence (AI), particularly involving natural language processing (NLP) and machine learning. These systems analyze spoken commands, interpret user queries, and generate appropriate responses. They learn from user interactions, improving their accuracy over time. By utilizing vast datasets, AI drives the understanding of context, enabling smart assistants to perform tasks such as answering questions, controlling smart home devices, or setting reminders. This innovation has transformed interactions between users and technology.
