Sure, autotune is a program that tries to identify a person’s singing pitch, then adjusts it to make it closer to the correct pitch.

do you know how does it works?
user
It’s based on spectrograms, which are the graphical representation of sound waves.  Auto tune essentially is a computer program that makes sound waves look like they are displayed in a spectrogram.  And if you compare the actual voice to the altered voice, it should look roughly similar to the spectrogram.

why do you think singers uses autotune? Isn't cheating?
user
People tend to use it for convenience and efficiency, especially if they are doing a lot of singing at once.  It also allows them to alter the pitch in parts where they think it could sound better, so it might save some of the work, if you will.  Other times it is used for artistic effect, because some people consider it more natural to sing that way.  I think that if you really want to use it for artistic effect, you should try to learn how to sing well enough that you can sing in a way that doesn’t require any adjustments.
