Dictate anywhere. WinWhispr types into whatever window has focus, so it works in apps that have no dictation of their own.
Speak your punctuation. Say "comma", "full stop", "question mark" or "new line" and you get the real thing.
Cancel a sentence. Press Esc while you are still holding the talk key and nothing is typed.
Talk without holding the key. Turn on Tap twice to keep listening in Dictation. Tap the talk key twice and it keeps going until you tap again.
Fix a name it keeps getting wrong. Open Dictionary, type the correct spelling and the way it comes out wrong. From then on it is corrected automatically. Only the exact words you list are ever changed.
See what you have said. Activity keeps every transcript, searchable, with the app it went into — plus your words per minute and how much time you have saved. It never leaves your machine.
