Internet Polyglot is a website for memorizing vocabulary words in dozens of languages. It has 44 “lessons” that cover topics like cars, time, religion, politics, feelings, measurements, and more. Each lesson is essentially a word list with native speaker pronunciation, an English translation, and a link to a picture to help you remember each word. There are picture games, matching games, guessing games, and typing games, plus a word search and a slide show that reviews all of the words in the lesson. Given that none of the vocabulary words in Internet Polyglot are taught using example sentences or context, learning vocabulary using this site may not be the best use of your time. You are probably better off using Anki to curate personalized vocabulary lists and downloading native speaker audio files from Forvo to accompany your flashcards. Nevertheless, you may find it useful if all you are looking for is a site that already has lists of vocabulary words with native speaker audio. If you are looking for audio files for less commonly-studied languages in context, you can check out iLoveLanguages.
