Quizlet has been on The Best Tools To Make Online Flashcards for awhile. In addition to letting you create and study flashcards, it also lets you study the words in “game” forms.

They’ve recently added audio to the flashcards you make. A fairly human-sounding computer-generated voice provides the sound at a click of the audio button. It’s definitely a nice addition.

Thanks to David Deubelbeiss for the tip.
