This feature is commonly found in devices like smartphones, Bluetooth headsets, and car infotainment systems. It uses voice commands or buttons to initiate calls, making it safer and more convenient, especially while driving. The technology typically relies on microphones and speakers to facilitate clear communication. Many systems also support features like voice assistants, enabling users to access contacts and manage calls using simple voice commands. This enhances user experience while promoting safety and multitasking.
