Thank you for the reply.
O.K. separate the level, from simple sentences which is like 1st grades study to more complex sentences. That is great idea.

I think sounds/voices are essential to learn how to speak language, as Rovian and Aviv100 mentioned. I'm foucused on that point for the site.
You see a sentence, and at the same time, you can listen the sound of the sentence you are looking at. After listen the sentence, you repeat the sentence. By doing this cycle, you learn reading/listening/speaking at once.

Japanesepod101.com is a good site. I can learn something from this site. thanks for the post.

I will finish the first draft version of the site by next week(9/24, Monday, Japan time). If you have any suggestions, please post your comment.

Thanks in advance.
