Although these devices may look similar at first glance and they all focus on disguising the voice, your main goal is to get a different timbre or tone of voice, to that no one can recognize you or it is difficult to do so.

To do this, it is important to carry out different tests through these devices until you get a result in which you do not look like a robot, or yes, depending on what you are looking for.

The voice distorter, as its name suggests, is responsible for distorting it by including noise, causing the spectrum of your timbre to be divided.

A voice changer focuses on taking this spectrum and modifying it, being able to play jokes or see how you start talking as if you just swallowed helium, as if you were a robot or as if you were the opposite sex.

Finally, the voice modulator, we can think of it as the same as the previous one. The main difference is that this one manages to fully capture your spectrum, achieving slightly more realistic results than the changer. This one also differs because it is intended for more professional use.
