Distributing speech voice from my pc to another

Hello all, I downloaded a program that speaks bulgarian text and it installs voice in Control Panel -> Speech Recognition -> Text To Speech and allows you to choose the bulgarian voice. So I want to use the voice in my application and the other people to use it. But they need to have the voice, otherwise the speech won't work. Where exactly are the voice files contained (Windows folder, registry...) and is there any way to copy them from my PC and to put the files in another PC, so the voice can work? Thanks for any help!

It's probably easiest to just download and install the program on the other PCs.

Yes, it is easy but I want to bypass that if there is an option. The best solution is to copy the voice files from my PC to another one. I just don't know where these files are.
