How to practice my German Pronunciation? Language learning sites?

Basically I'm learning German as I'm currently living in Germany. I will be taking classes eventually but unfortunately they are not starting until after xmas so I'm getting started on sites such as Duolingo problem is I want to practice my pronunciation. I've heard stories of Indians who are trying to learn English to use the Iphones Siri to practice their pronunciation on.
Is there a way that I can practice my pronunciation of German online perhaps by using a speech to text program or something similar to Siri?
