The Edict Audio Companion puts them all together. It's got all the advantages of my custom version of Edict (see my Edict page) plus a very special feature. The entries for all 8,054 Japanese words on all four levels of the JLPT contain links to 's JLPT vocabulary mp3 files--tap a link, hear the word pronounced! No other system has as many words pronounced by a real human being, and no other system gives you such top quality audio. Here's what you'll see when you look up a word that's among those 8,054 words (actually, with variations on how the words are written, there are quite a few more).

Simply tap the green link and hear the word. Easy as pie!
The audio files in the Edict Audio Companion were originally created to be audio flashcards to be used in studying for the Japanese Language Proficiency Tests (previous format, but the same vocabulary words). Purchase of the Edict Audio Companion includes the entire set of Audio Flashcard files, all set up and ready to use as an audio flashcard study system as well as a dictionary. The JLT pronounces an English word, then pauses to give you time to say the Japanese. Then the system pronounces the English word so you can confirm that you were correct. And of course it goes the other way, too, pronouncing and showing a Japanese word, then pausing for you to say the English. Many people find this kind of spoken learning a highly effective complement to the visual learning of most typical study methods.
