Please strongly consider adding in a text-to-speech engine to read back cards automatically. I've been playing with an app called "iSpeech TTS" which has downloadable engines for multiple languages and sounds quite good. You could implement this feature as an in-app purchase and allow the language(s) to be chosen. For a little background - I've been using your app to great effect for studying Korean. I type the korean word or phrase in the Korean script and English on the other 'facet'. I recently realized your app can play back cards automatically. My thought is to have cards play back automatically while I'm at work and just listen to the audio of the words being read. I've already tested out iSpeech's ability to read English and Korean and it's terrific (even according to a native Korean). As an iOS developer myself, I don't even think this should be too hard for you guys. Just license an engine (Please make it a good one with multi-lingual/Korean support), plug it in and make it an in-app purchase feature and you're good to go! Thanks.
