I know this may have been discussed before, and I know Lingq has limited funds for development of this sort, but I think some kind of feature where users can record a text in their target language for critique and guidance by native speakers on their accent. I know it would be very useful for me in getting closer to certain specific sounds.
I will propose 2 solutions for you since I doubt that that kind of feature will be developed in the near future or at all.
You could arrange a meeting on skype with a native of your target language or a tutor. Also, you could record video of yourself and put them on youtube and ask people of this forum or any others one to give you the guidance you need.
you tube it is : )
And pretty soon you will be able to post these videos on your wall for your friends to see. Don’t tell anyone I told you.
