He says he uses TTS, and he wants to know if there is a way to automatically turn over the card (to the answer side I guess). I know there is a slideshow type addon for desktop, but I'm not sure about for AnkiDroid.
He also wants to know if there is a way to control the speed of TTS and make it a bit faster.
And if there is a way to use TTS in the background -- I'm not sure exactly what he means here, I think since he wants the cards to go automatically, he wants the screen off and just listen to all cards while on the subway. He says this will save battery usage.
