Our code for incorporating TTS into the quiz. We ran out of time and we had a lot of complications with team member's availability and such, so we weren't able to finish the project fully. There are some bugs in both codes that have yet to be worked out but this is what we have thus far. Our team is me, Enlun Yin, Othmane Harraq, Ryan Chan, and Gaurab (We are all freshman and just wanted to get some experience making a project together, having fun, and being in an environment with higher level programmers and absorb as much information as possible. Thank you OwlHacks for a great time!!!!! :)
