What can’t talk but will reply when spoken to

An echo

Explanation:

An echo is a natural phenomenon when sound reflects back to the listener with a delay after the actual sound time. When we shout and then we could hear the same sound back, that is called the echo. So it doesn't come without one making a sound. So it is only a reply and can not initiate sound production first.

An echo.

Explanation:

Of course, no self-respecting echo can talk-- it's simply not alive. However, if you shout something into a cave, it "shouts" it back which, technically, allows it to reply to you.

not everyone is always right.
