Few days back I mentioned about a free voice changer software that you can use for many purposes like recording the voice in different voice or while playing games but here is a software that is used solely for changing Voice when using Skype.
The software has many filters for adding different tones to the voice. The software may look bit complex but if you use it, you will know how simple it is to use. Multiple filters can be combined with each other to use all their effects for the voice changing process.
1. Microsoft .Net Framework 2.0 installed in the system
2. The software currently works in Windows.
So just install the tool and let the fun begin.
