 I like the idea, I ran into some voices that were missing and Sapi 4 was changed to Sapi 5.  After downloading the voice I had used in the past I was happy but had to change back to Sapi 4. Infomation can be found on the web, quite a few free voices but many can be expensive making it hard to evaluate them.
