You could also base it off Twitch commentary from ServerSmash videos and such. The problem bases are usually the big bases (biolab, etc.) after all.

Fiddling with the OS X TTS engine yields:
Andvari - And Vah-ri
Palos - Paylos (unless I'm saying it wrong)
Eisa - I-sah
Ymir - Ymeer
Onatha - O-natha
Mekala - Meh-kala
Wokuk - Woe-kuk
Ixtab - Ick-stab
Hvar - Hhvar
Dahaka - the-hahka
VS - V S. Otherwise it reads Versus.

Unsure:
Genudine - Genu-deen or Genudyne?
Acan - Ay-can or Akan?

Problematic:
Ikanam. The short I sound will not come out right at all, and when it does the A's become long A's.

All other bases seem to pose no problem running through the TTS engine, including Mattherson and Waterson.

I had just a simple alert sound in mind but that's even better than what I imagined!
The only issue I see with it is the weird pronunciation of bases. For example, I've heard people pronounce Mekala as "Mekaala" (I use this) or something like "Michaela"; OS X's speech program says it "Mechla".
