Bane's voice sounds different because many people who saw the prologue said that he was extremely hard to understand. So Nolan jacked up his voice to where it almost sounds like he is narrating every scene he is in.
You don't know where Bane is from, but you know that he spent most his life in the pit.

There are similarities between Joker and Bane, but Bane was more methodical and his plan was laid out to totally incapacitate everything, isolating Gotham from the rest of the country. In true League of Shadows fashion, he infiltrated a corrupt system to where he could implement his plan without raising an eyebrow by anyone. Even Daggot wasn't concerned about the money he was spending and all the construction Bane was doing because all he wanted was Wayne Enterprise.
