English to Kana/Kanji Test Site?

Someone posted a while a go a site where it would ask you in English for the reading from your API key. Would be much appreciated!

I find that I am growing a pair of blinders. I am so honed in on reading the actually kanji I do not step back and look at the whole word. For instance I have messed up the insanely easy 息子 a few times because I was trying to sound it out and not look at it as a whole. I feel like the requested site might help.
