First, you will need to open Animaze and open the Voice Effects Gallery. From the Voice Effect Gallery, you can see the Voice Skins shelf, you can choose which to buy and start using

You can make a test recording and play it back to test the Voice Skin by using the “Record with your Voice”, or activate the Voice Skin and record a video, you choose the option that best suits you.

Keep in mind that in order to use Voice Skins with your Stream, you will need to install Animaze Virtual Microphone (find out here).

Just a note that the developers from Module and us recommend having a discrete, noise-canceling headset microphone used in a quiet, single-speaker environment to obtain the best results. 

We recommend headsets specifically for voice skin users, for example the Steelseries Arctis Lineup or as well as the HyperX Cloud II. Microphone plays a large role in resulting quality, whether as part of a headset or condenser mic streaming setup.
