Voice command is a technology that allows users to control devices and applications using spoken words. It utilizes speech recognition software to interpret and execute commands, making it easier to interact with gadgets like smartphones, smart speakers, and home automation systems. This hands-free approach enhances convenience and accessibility for users. Common examples of voice command include virtual assistants like Siri, Alexa, and Google Assistant. These systems can perform various tasks, such as setting reminders, playing music, or controlling smart home devices, all through simple voice instructions. This technology continues to evolve, improving accuracy and expanding its capabilities.
