I've heard about Soundclound or some programmes like that, which is pretty neat to get your pronunciation corrected by natives without bothering them on Skype (Especially if you're in different time zones).

However, turned out it wasn't completely free: I recorded some short record then suddenly they asked me to pay a small fee if I want to continue.

This was a long time ago so I don't remember correctly, but it was something like that.

So do you guys know any similar website which provides such service but completely free?

If not, is there any other method I can use to share my record (it has to be convenient for both side) on the internet? Thanks a lot.
