Riddle: Whisper of the Wind

I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I?

Can you guess the answer?

The answer to this riddle is an “echo.”

An echo “speaks” without a mouth and “hears” without ears because it is the sound reflected off surfaces. It doesn’t have a physical body, but it becomes audible when sound waves bounce off objects and return to the listener.
