Voice assistants

AI-powered software agents like Amazon Alexa and Apple's Siri use Natural Language Processing (NLP) to execute commands, manage smart devices, and retrieve information via spoken word.

Voice assistants are AI-powered software agents, fundamentally redefining human-machine interaction: they process spoken commands to execute tasks. Core technology relies on Automatic Speech Recognition (ASR) to convert voice to text, followed by Natural Language Processing (NLP) to interpret user intent. Major players dominate the market (Amazon's Alexa, Apple's Siri, Google Assistant), collectively reaching billions of users globally across mobile and dedicated smart-speaker platforms (e.g., Google Home, Apple HomePod). These systems manage everything from setting a 7:00 AM alarm to controlling smart home thermostats, driving efficiency and accessibility for consumers and businesses alike.
