The former England Under-21 international defender, who has played the full 90 minutes in the Owls' last two matches since arriving for an initial month from West Ham, is grateful to be playing first-team football.
"I've enjoyed it very much so far, the boys here are a really good bunch and they've made it as easy as it can be to come to a different city and quickly settle in," Spence said.
"I jumped at the chance to come up here because I'm at an age now where I need to be playing regularly - I want to go out and show how good a footballer I am.
"The only way to do that is on a stage where you play week in, week out and while I'll always look for West Ham's results - I've been there since I was 15 - I'm at Sheffield Wednesday at this moment in time and hopefully I can make them a better football team.
"I've not thought too much about beyond my original loan spell. I'm just focussing on the games ahead, but if I was given the chance of staying longer, I'd be happy to do so.
"If you play well in this game everything else looks after itself and that's what I'm looking to do.
"I want to play in the Premier League. Every footballer does. You want to play at the highest level, but in order to achieve that I need to play more first-team football and prove myself."
Spence is expected to resume in manager Dave Jones' starting line-up at Birmingham on Saturday when the Owls will be chasing their first league win of the season.
