You can’t get rid of echoes. Echoes are your own voice arriving multiple times at the microphone late having bounced from the walls and ceiling. If effect, you’d be asking the software to remove you from yourself.
You can suppress echoes with fancy expensive microphones or very close talking in directional microphones, but the best way is to record in a room that has no echoes. The fashion of designing houses with polished wooden floors and bare walls means, without putting too fine a point on it, you will never record good quality sound in there.
This clip will always sound like she recorded in her mum’s kitchen.
