Semi-unmanned live recording video sound is your own?
Yes, because of the phenomenon of bone-to-bone sound transmission, the sound you hear is different from what others hear, so the sound in the tape recorder is the same as what others hear.

People usually hear their own voices, not only from their ears, but also by vibrating the vocal cords of the brain and reaching their ears through bones and muscles. When using a tape recorder, the sound they hear only reaches their ears from the air. This makes the tone of speech different, but the voice heard in the tape recorder is the voice that others usually hear when they speak.

Sound travels in the form of "longitudinal waves" in the air.

Longitudinal wave is a wave whose vibration direction and propagation direction are coaxial. For example, when a gong is struck, the vibration direction of the gong is consistent with the propagation direction of the wave, then the sound wave is the longitudinal wave. Longitudinal wave is a kind of fluctuation (fluctuation is divided into transverse wave and longitudinal wave). Also known as "dense wave", the propagation process of longitudinal wave has different dense parts along the direction of wave progress.
