Direct voice input is when you talk to your computer or phone and it understands what you say without you having to type it. It's like having a magic genie in your device that can understand your words and turn them into text. Imagine if you were talking to a friend, and they understood everything you said and wrote it down for you. That's what direct voice input does, except it's the computer or phone that is doing the writing for you. It can help you write an email, message, or search for something on the internet without having to type it. All you have to do is talk to your device, and it will do the rest!
