What can’t talk but will reply when spoken to

Answer 1

An echo.

Step-by-step 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.

Answer 2

An echo

Step-by-step 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.
