Fantastic!
However, I couldn't find neither feedback, nor my question answered in FAQ.
They do not list post-USSR countries in accent selection
Neither preference in sound quality (I can record by both webcam audio and by semi-professional studio equipment). Also there are no guides for reading, e.g. should it be as neutral as possible, or with some artistic feel to it? Well, actually those are not too important, but might make the audition a bit better.
To everybody:
Recording your voice is not the only way to easily help the engine. You may just listen and mark other's auditions as valid, `cause it's damn hell of manual work.
