Voice interaction refers to the technology that allows users to communicate with devices using spoken language. This can include smart speakers, smartphones, and virtual assistants like Siri, Alexa, or Google Assistant. Users can perform tasks such as setting reminders, playing music, or asking questions simply by speaking. The underlying technology often involves speech recognition, which converts spoken words into text, and natural language processing, which helps the device understand and respond appropriately. Voice interaction enhances user experience by providing a hands-free way to interact with technology, making it more accessible and convenient for people of all ages.
