Don't know if anybody wants them for fangaming projects and such, But Azu of Retro did a (almost) english full voice dump of Generations:
http://dl.dropbox.co.../Rips/Voices.7zIts a whopping 351 MBs and its in a .7z archive which means you'll need 7-zip to extract it.
don't let all the sub-directeries overwelm you when you first start looking around. there basically empty directorys within directorys *insert inception joke here*
Heres the run down in what is in each folder:
Voices\30VCE_BLB_NP_EN.cpk_unpacked\Synth\3000000_voice\3500000_VCE_BLB_EN = Final Boss Battle Character voice clips ("SONIC, LOOK OUT! THAT LOOKS LIKE A HOMING SHOT!! and such)
Voices\30VCE_BOS_EG_EN.cpk_unpacked\Synth\3000000_voice\3010000_VCE_BOS_EG_EN = Eggman Classic and Modern's voice clips. Egg Dragoon's fight is in there too.
Voices\30VCE_EVT_NP_EN.cpk_unpacked\Synth\3000000_voice\3700000_VCE_EVT_EN = Character has been freed voice clips ("Thanks Sonic. You did a good job back there. Btw, Did you gain weight?!" and such)
Voices\30VCE_HNT_EN_WIN32.cpk_unpacked\Synth\3000000_voice\3800000_VCE_HNT_EN\xbox360 = All Omochao. ("Press the A button to jump!" and such)
Voices\30VCE_STE_EN.cpk_unpacked\Synth\3000000_voice\3900000_VCE_STE_EN = Cutscene's audio. all except 3 are there. The introduction cutscene, the cutscene when the sonics find out whos behind the time eater mess, and the cutscene when sonic says goodbye to his classic self. I'm sure Azu will look into it once he is less busy.
Voices\character voices = This one should be a no brainer but basically its all the character voices including sonic.
