A voice drifts when the speaker slowly moves away from the microphone or turns their head. The level falls and the tone thins. Level the sections, match the tone, and reduce the room noise that rises when the voice gets quieter. Prevent it next time with a fixed seat and a marker.
A voice that drifts sounds fine at the start and then gets quieter and thinner as the speaker moves. It often happens in long takes, when people lean back, relax, or turn toward a second person. The change is gradual, which makes it easy to miss until playback.
Moving away from a microphone reduces the level and changes the tone. The voice loses its close, warm sound, and the room becomes more noticeable. Turning the head changes the angle, so consonants and high frequencies also shift. Each change is small, but together they make the sound feel like it moved.
Split the recording into a few sections, and level each one to match the start. Use small gain changes at the joins, and check each one by listening. The uneven volume post shows the steps for a full level match.
When the distance has changed, the tone often changes too. A gentle low shelf can restore warmth to a section that thinned out. Match the tone section by section, rather than applying one setting to the whole take, so the start and end still sound alike.
As the voice gets quieter, the room noise becomes more noticeable. Apply noise reduction gently to the quieter sections, or raise the level only after the noise is controlled. Keep the amount of reduction the same across sections, so the background does not change.
Mark the microphone position and the seat with tape. Place the microphone so the speaker can move slightly without changing the distance. Use a stand, a chair that does not roll, and a reminder to stay in place. Record shorter takes, so the drift has less time to build.
Repairing drift is slower than preventing it. Heavy levelling can make the sound unnatural, so keep each change small. If the drift is strong, re-record the section rather than repairing it.

The speaker often moves away or turns. Mark the position and take shorter breaks.
It can improve it a lot. It cannot fully restore the close, warm sound of a voice that moved away.
Apply it consistently, but check the quieter sections most carefully, because the noise shows there.
A fixed seat and a marker on the desk. It costs nothing and works every time.
