Enter spoken words in game

Hey guys,

I'm currently trying to make a game with friends that relies heavily on audio. We have two options, but we can't figure out either one. Option 1 is hearing a voice, and typing in the word you heard, and option 2 is hearing the word, having buttons appear, and selecting the right button before the time runs out. We are all fairly new to unity, and programming in general, so we've opted to use Javascript. Any help or suggestions would be greatly appreciated.
