I'm sure I've seen this somewhere in the forums, but no search will bring it up:
Hands-free Flashcards!
... I dream of the day when I can use TTS in both English and Chinese and have audio flashcards and be running on a treadmill and practicing as I exercise... Okay, actually I never run on a treadmill, but other people do, and I'd still totally use them when walking to classes, the bus, etc.
However, this brings up the question of how you would select all of the different choices, hands free. Supposedly, back in the day Ankidroid tried to do this with a Bluetooth gaming controller called "Zeemote". It's wireless, hopefully ergonomically designed (I've never actually used it), and is used with one hand. There must be other wireless Bluetooth game controllers or something out there that you could also use... Have you had any other ideas of how to do hands free? Maybe even by voice, although to be honest, from what I've seen, it would be pretty annoying to use voice commands, because they might mess up. Furthermore, it would really limit where you studied, and background noise on a train, for instance, might be a problem. I'd much rather some kind of controller thing...
One more suggestion pertaining to audio flashcards.
First let me say that I doubt you will want to do this, but I'll ask anyways. The tts (the one I have is Hui) can be really nice for some sentences, and not so nice for others. I'm sure you guys are working on this, but I'm wondering you'd also consider letting people import audio with their flashcards. No matter how good tts is, I'll probably almost always go for the native audio if I have it (which, of course, when I don't, tts is great!). What I'd really like to use it for is to splice movies up into small fragments (using subs2srs) and making audio flashcards with the audio. For some movies, it's so amazingly natural - no textbook perfection for me, no sir. It really helps for hearing (and trying to mimic) how people actually speak. What would be awesome is if we could import any audio, to the front or the back of the card. That would be totally cool.
