Voice notes can be a handy way of recording ideas and reminders while on the go. But in audio form, they have limitations: You can’t easily search through them, and you can’t quickly check them when you need to be quiet (in the library, for example, or next to a sleeping partner). This is where transcribing comes in, enabling you to have both the voice recording and the written text available.
