Sometimes(very often!) we need to add effects on our voice recording. To make it sound better, to make it sound thicker, or just to maker it sound incredible!
For widening/thickening, or making choir like voices, you can use : chorus, voice multiplier, voice doubler, stereo wideners.
For radical changes or special FX, you can use harmonizer / pitch changing, genre changer, pitch correction / autotune.

Here’s a top 5 of free VST effects for changing the voice :

1) Azurite multi voice chorus VST

• Download Free Chorus AU VST Plugins & VSTi Instruments Here is our colection of FREE software, VST plugins, VSTi instruments, audio utilities and DAWs. Should you know of anything that we have not listed here let us know.
• Size 5.45 MB UD Chorus is a chorus unit with reverb and tremolo sections.

Acon Digital Multiply is the winner of the KVR Audio Developer Contest 2014. Acon Digital Multiply is a free and versatile chorus effect with a unique twist. Each simulated voice is processed with a phase randomizing filter so that unpleasant comb filter effects are avoided.

This great chorus can work on many type of sources : guitar, voice, etc.
It works nicely for voice, it’s not too hard/harsh and does a good job on mono inputs for spreading voices and give a stereo effect.

5) ag-works chorus ch-2

Chorus CH-2 VST

Here, at Wavosaur, we love the monstachorus VST by Betabugs, but i thought the Chorus CH-2 is lesser known, and deserve some exposure. It’s like having 4 independant chorus you can tweak in parallel.
