Voice User Interface (VUI) is an incredible technology that allows users to engage in natural language conversations with machines. Here are some examples of Voice User Interface (VUI) in action:

• Voice assistants: Well-known voice assistants like Amazon Alexa, Google Assistant, and Apple's Siri are excellent illustrations of VUI. Users can interact with these assistants by simply speaking commands or asking questions to obtain information, perform tasks, or control connected devices.
• Voice-activated smart devices: Devices such as smart speakers or smart home systems make great use of VUI. Users can effortlessly give voice commands to play music, control smart home devices, set timers, receive weather updates, or carry out other tasks without the need for physical buttons or interfaces.
• Voice-enabled applications: Many applications integrate voice commands to offer hands-free control and enhance the user experience. For instance, a mobile application with voice search capability allows users to verbally search for information or navigate through the app using voice commands.
• Automotive voice control systems: Modern vehicles often incorporate VUI for convenient, hands-free control of various functions. Drivers can use voice commands to make phone calls, adjust temperature settings, play music, get directions, or send text messages, all while keeping their hands on the steering wheel.
• Interactive voice response (IVR) systems: IVR systems, commonly employed in customer service or call centers, rely on VUI. Users can easily navigate menus, provide spoken responses to prompts, or access information by interacting with an automated voice system.^[1]
