The voice you hear in the recording is your real voice, which is different from the voice you usually hear when you talk and sing. Because the mouth, nasal cavity and cochlea in your ear are connected when you speak, there are two voices when you speak, one in your ear and the other outside your ear, and the two voices work together, so it is different for you to hear your own voice from others. And the recording can reflect your real voice. Besides recording, you can also hear your real voice when you talk with your ears covered!
