This is how to Setup Voicemod on League of Legends:

• Voicemod has to be opened in order to feed the virtual microphone. 
• Open League of Legends. 
• On the top right side of the client, click on Settings. 
• Go to the Voice section. 
• Set Voicemod Virtual Audio device microphone as your input device. 
• It is Done! 

Now back to Voicemod app and select your favorite voice. Enjoy!

*Do not use the Voicemod Virtual Audio device as the output (headphones), we need it internally as an audio bridge to make all this work.

Through this output, you will hear the transformed voice if Voicemod is open, but not the rest of the sounds coming from games or other applications.
