Voice calls are a way to communicate with someone using a telephone or a mobile device. When you make a voice call, your voice is converted into sound waves and transmitted over a network, allowing you to talk to someone in real-time. This is a common method of communication, whether you're calling a friend, family member, or a business. With the rise of technology, voice calls can now also be made over the internet using apps like Skype or WhatsApp. These services often allow for clearer sound quality and sometimes even video calls, making it easier to connect with people no matter where they are in the world.
