Today, voice messaging is a popular function that people use to send their spoken recorded messages. In terms of its advantages, mobile users can create voice messages quickly and easily via smartphones.  It can help save time on typing and avoid spelling mistakes. It’s also very convenient to contact others if you don’t want to show your face or cannot make video calls. As for its disadvantages, this modern communication needs a stable Internet access. In addition, for some people, checking voice messages is rather inconvenient and answering them might be done later. In short, voice messaging has both pros and cons. I think people will still use it as a common way of communication in the future.
