Echoes or reverb are your own voice arriving at the microphone more than once having bounced from the walls and ceiling. You are, in effect, asking the software to remove your voice from itself.
You might think that simple sound gates would help because echoes are always lower volume than the main voice. But no. That may work a little if you have one echo from one wall, once. But if you have more than one the gates will go nuts trying to suppress echoes without affecting the main voice.
Then there’s the serious problem of the performer not being able to have theatrical expression, volume change, or head movement.
So far, creating a quiet, echo-free environment is The Way.

People have been able to create pleasant sound tracks by recording in their car. That does work.
