Hold Right Ctrl in any LINE message box and talk. It comes out short and natural, the way people actually write there.
yeah um sounds good, I'll have the draft over by three three o'clock send
Perfect Dictation sees that you are in LINE and writes the way messages are written. Change it any time, or make a style of your own.
Want it different? Make your own style in plain words, like "keep it under three short sentences".
All of them work in every app, and none of them needs a plugin.
Select text you already typed, hold both keys and say how to change it: "make this friendlier", "shorter".
End with the word "send" and it presses Enter for you. Leave it off and the text waits for you to check it.
Fix a name once in History and it is spelled that way from then on: people, products, your company.
No. Perfect Dictation types into whatever window has your cursor, so there is nothing to install in LINE and nothing to connect.
No. It only sees the app's name, to pick the style. It never reads what is on screen, and your words are not kept on our servers.
Only if you say "send" at the end. Otherwise the text waits in the box until you press Enter yourself.
