Remember back in the Sega Genesis days some games made by Sega have the voice intro?

ex. when you start Sonic game in the beginning there's a voice that say "Sega"

where can I get the WAV voice sample for that?

If you have a ROM for Sonic the Hedgehog then use WAV logging in Kega Fusion (or a similar emulator) to save the original sound out as a WAV file!
