If there is too much blood, I can remove some

why can't my crazy characters just hear one voice
why do they always have to hear several distinct voices
this is a problem

phoenix doesn't count as the contest hasn't been judged yet [ though tbh i'm fairly confident i would win ], but he would hear anywhere from 2 to 4 i think
i don't really know how many william would've heard, maybe 2 or 3
alice hears 5
nero hears at least 5
and i have no idea how many glados would hear, but considering the corrupt cores and that in game GLaDOS mentions she's "heard voices all her life", so it's probably at the very least 6, likely closer to 8 - 10 though knowing my characters and the horrors i seem to love to inflict on them, i wouldn't be surprised if it was in the ballpark of 16 - 20+ voices

Cain hears ALL OF THE VOICES XD

to be honest that probably more or less sums up what happened to glados as well XD
