Autocorrect is disabled on the type-in-the-answer field, since you’re not really testing your ability to spell the word if the device corrects it for you. If you just want to confirm you remembered the word in question, I’d recommend you either a) rate the card as correct when you make a typo, or b) just say the word out loud prior to answering the card, instead of typing it in, as doing so will allow you to get through cards considerably faster.
