I’ve been enjoying this Great Language Game and wanted to recommend it to others. You listen to a clip in one of 80 languages and are given choices to decide which one it represents. At first you choose between two, but as you advance in the game, you are given an increasing number of choices making your job of picking the right one potentially harder. I say potentially, because if you’re certain of the language then it won’t make a difference, but if you are not then the guessing definitely gets much harder especially depending on the options. For example, I can certainly tell the difference between Cantonese and Japanese, but I cannot between Cantonese and Mandarin. Obviously, your personal experiences will help in various ways. I’m unlikely to be confused by languages I speak or have studied even for a little while (in my case a healthy variety: Hungarian, German, Russian, Japanese, French, Italian, Spanish), but have not the first clue about how to identify languages such as Bangla, Dinka, Tagalog or Tongan, just to name a few on the list that are completely foreign to me. Some others fall in between in my experience (like Slavic and Germanic languages) where I’ve done a reasonably good job guessing even if I couldn’t have been sure.
The game’s author has shared some interesting stats about how people have been doing. I got a 750 my first round and wish I could say I have only improved since, but in fact I have not been able to maintain that throughout my attempts. I’ve found the experience interesting for thinking about what features of languages I look for in trying to identify them.
