Unless you have lived for an extended period in Kansai, speaking one of the many dialects that fall under the umbrella of Kansai-ben is a little strange.

Often voice actors who play characters from Osaka aren't actually Osaka natives, and their accent can be picked up in a second from a native speaker.

But it is good info to know if you are travelling or are going to live in the Kansai area and speak Japanese. There are books written on the subject, and I was with friend from Shikoku who moved to Osaka for work, and he was considering picking up a book on Kansai-ben.

Nyororin or Nagoyankee can confirm or deny this, but I noticed men in Nagoya speak with a sort of Kansai dialect (using ~へん　and あかん）
