Voice commands are instructions given to a device using spoken words. This technology allows users to interact with devices like smartphones, smart speakers, and voice assistants without needing to touch them. By recognizing specific phrases or keywords, these devices can perform tasks such as playing music, setting reminders, or answering questions. The underlying technology for voice commands often involves speech recognition and natural language processing. These systems convert spoken language into text and interpret its meaning, enabling the device to respond appropriately. As a result, voice commands provide a hands-free way to control technology, making it more accessible and convenient for users.
