More about this voice

Echo and reverb are two different things

	Echo	Reverb
What it is	Distinct repeats of what you said	A smooth wash of sound around you
In this preset	Every 0.28 s, 30% mix	4 s long, 45% mix
Sounds like	Shouting across a canyon	Standing in a cathedral
Slider	Echo	Reverb and Reverb length

The two clips under the main one split them apart: one with only the echo (a classic slap-back), one with only a shorter 1.5-second reverb (a big hall).

Keep it from turning to mush

Use headphones. If your speakers play the echo back into the mic, it repeats forever.
Speak in short phrases and let them ring. Long sentences blur into the tail.
In calls, lower Reverb length to 1–2 seconds; people can still answer you.
Turn off the call app's noise suppression. It treats the tail as noise and chops it.

Free echo voice changer FAQ

Does the echo change my pitch?

No. The Cave Echo preset keeps your voice as it is and only adds space. Combine it with Pitch if you want a giant in a cave.

Why is the echo not heard in my call?

Call apps' noise suppression and echo cancellation remove tails like this. Turn them off in the app's audio settings.

Can I add echo to a recording?

Yes. Open the Online Voice Changer, add the file, pick Cave Echo and download the WAV.
