Your voice sounds like it was recorded in an empty hall, and the cleanup tool barely helps. That is not the tool failing - echo is the one recording problem software fundamentally cannot delete. Here is why, and what actually fixes it.
There is a reason the fan noise in your recording disappears in the cleanup but the hollow, bathroom-like echo stays. It is not a settings problem. Echo is built out of your own voice, and that changes everything about how it can be fixed.
Example grading. Steady noises sit separate from your voice; echo IS your voice, repeated - which is why no cleaner fully deletes it.
Echo in a recording is not a separate noise. It is your own voice bouncing off hard surfaces - bare walls, tiles, a ceiling, a glass window - and arriving at the mic a fraction of a second later, again and again. By the time it is in your file, your voice and its echoes are one single waveform.
That is why AI cleanup tools, including the vocal remover in the video, can only reduce echo, never truly erase it. Steady fan noise is easy because it sounds nothing like speech. Echo sounds exactly like you, just quieter and later - the tool cannot always tell where you end and the room begins.
Stand where you record and clap once, sharply. If you hear a fluttering ring or a small tail after the clap, your voice recordings have the same tail after every word. Add soft material until the clap sounds like a single dry snap. This test costs nothing and tells you more than any software meter.
You have three honest options. Best: re-record in the treated spot - echo is the one flaw where re-recording almost always beats repair. Acceptable: run the cleanup from the video and accept a partial reduction - the result is more listenable, just not dry and studio-like. Never: stack heavy echo-removal on top of heavy noise removal - each pass eats a little more of your actual voice, and the result turns watery and robotic.

▶️ Watch Full VideoFan noise is a constant sound that is completely different from speech, so the tool can identify and subtract it. Echo is your own voice reflected back - the tool hears speech on top of speech and cannot fully separate the two without damaging your voice.
Editors offer dereverb effects, and they reduce echo the same partial way AI cleaners do. They are useful for making a bad take acceptable, but none of them turns a hall recording into a studio recording. The room fix is always the real fix.
The smallest furnished bedroom, with curtains drawn and the door closed. Beds, clothes and soft furniture absorb reflections. Avoid kitchens, bathrooms and empty rooms with tiles - they are the worst echo chambers in any house.
