It’s never actually TRULY revealed, but as if you havn’t found it obvious, it’s Sephiroth. Sephiroth later explains to Cloud in the game that he is but a puppet. As in, he tells him what to do, and Cloud does as Sephiroth commands. Cloud refuses to believe it…but anyway.
Yeah, it’s Seph. Any other questions? post it or PM me.
i have another question (i’m only at the part where u sneak onto the boat and find sephiroth) when do u go on the date? i’ve been trying so hard to go out with barret cuz it would be so funny, am i even close.
*Spoilers*
You don’t know that it’s Sephiroth. In fact, it’s equally as plausible to ascertain that it was JENOVA dictating the actions of Cloud – after all, it was HER cells that he had infused into his own (although scientifically, this makes no real sense… hell, it’s a game), not Sephiroth’s. This leads to the question "Was Sephiroth a marionette as well…?" And unfortuantely I’m not going to answer it (here) because I’ll save that for if and when I get a place to post my theories (of which there are many, and of which this is one of).
Additionally, the voice in Cloud’s head could be a stream of supressed memories trying to escape from the inner recesses of his subconcious. Wrought with turmoil, the "real" Cloud could be trying to burn through the thick fog of lies with a single voice of truth trying to guide him towards what really happened 5 years prior to the game in Nibelheim.
Thirdly, we may even go so far as to think it was Zack’s voice, because he was so close to the former SOLDIER. People have reported many instances where loved ones have made apparations and/or brought messages from beyond the grave (whether or not these are true are debatebale). Seeing as FF7 already bends the laws of science, why not bring in supernatural ideas as well?
Building off of this, it is probably more plausible to say that it is "Zack." (Zack in quotes is different from Zack without). "Zack" is nothing but an alternate personality concieved by Cloud after Zack was murdered at the hands of Shinra MP’s outside of Midgar just prior to the game’s beginning (or was he? No substantial proof of his death, but let’s not get into that). This "guiding voice" may be Cloud’s form of coping with the trauma of not being able to save his best friend from the bloody hands of the Shinra, from not being there to protect Tifa from Sephiroth, and from not being there to protect Tifa from falling off of the bridge (Cloud’s early childhood). Split personalities are well documented, too. Who knows!?
BTW, you can expect more of this kinda stuff (much longer too) if I ever get a place to post my theories (I’m new and I’m not sure if it’d be okay to just start making threads based on my theories).

..but isn’t it just so inevitable that it was Sephiroth? Believe what you want…::Shrugs::

Cuz he’d miss her, right? She cared about him a lot…
Maybe it’s her spirit trying to be with her son, it’s a nice thought…
I mean, he’d seen her the day she died, probably had lunch, and had a chat, like when he was young. And then Sephiroth came and burned down the town, and killed her, and left Cloud with no family. That musta pissed him off…
So I think it’s his mums voice, or what he remembers of his mum…

And that gap will deffo be Yuffie cus you can get Yuffie before you go to Junon Harbour and you don’t get Vincent until Nibelhiem.
