This is not an official FCC project, but I’d love feedback and bug-checking on it anyway. My daughter brought home a list of spelling words. I thought, “I bet I could write a simple app to act like audio flashcards, checking input spelling against the list.” One week later: http://codepen.io/AbdiViklas/pen/PbZqPK
I used the Merriam-Webster api for audio, which proved super frustrating, returning only XML and being so inconsistent in structure that I had to hard-code some words around it by hand, but I patched the exceptions with the awesome HTML5 text-to-speech API (did you know that you can make the browser speak text, and recognize spoken word, with a couple of lines of code? I do now.)
