I definitely wouldn´t recommend google translate for improving pronunciation, it's just not natural and it's absolutely boring...
What I did the most is listening to the podcast on my mp3. Those are short episodes with real-life situations and are suitable for all levels, as you can find a lot of it online. The one I liked the most is the one from British Council learning portal. They talk about loads of interesting everyday topics, jokes, so there is something for everyone :)

In the podcast there is also a girl who came to UK from Venezuela, if I remember well, and all the funny situations she went trough while learning english.
Although it's called elementary podcast, it can help a lot to someone on higher level as well...
I hope it will help you, and have a good time listening to it :)
