You can get a lot of additional voices from Cepstral: http://www.cepstral.com/en/personal/download

It appears that available voices are the same as CereProc has on offer: https://www.cereproc.com/en/storesapi.

When you download their software you get selected voice registered in Windows, so you can use it with SpeechSynthesizer.
