Declined
Improved audio sources
The audio for some of the words is very, very weird. Particularly there is a male voice that always sounds like it's asking a question because the intonation at the end of the word is "pitched up" if you will.
There are free audio sources (like Japanese pod), and Awesome TTS (used in anki) also gives access to some high quality voices that would be much, much better. Even Forvo would be better.
