I speak without a mouth and hear without ears. I have no body, but I come alive with the wind. What am I? (27/31)

Often rational questions are not difficult to answer; all that is needed is logical thought to find the answer. The given question is a fascinating riddle that allows one to think logically. The clue is in the issue itself. An echo is a signal that echoes back to its source. When the sound waves are reflected back, it is a repetitive sound. An echo talks without using its mouth and listens without using its ears. The wind brings it to life.

As a result, the required answer to this riddle is ‘an echo.’
