Solution:

An Echo

An echo is a reflection of sound waves. It "speaks" because it repeats the sound it hears without having an actual mouth to produce sounds. It "hears" because it listens to the original sound and then reflects it back. It has no physical body because it is just a sound wave traveling through the air. When the wind carries sound waves, the echo is "brought to life" as it reflects and repeats the sound, making it seem as though it has come alive with the wind.
