Fixed various citation issues.

Realized I was citing my own 2012 ICASSP paper incorrectly. That has
been updated on the website. Also uploaded fixed verions for the thesis
and 2012 Interspeech paper to cite the ICASSP paper correctly.

Noticed that citations from my thesis did not make it on Google Scholar.
It may be due to the fact on electronic version was inaccessible. OSU
changed the way they handle the online versions, so my link was dead.
Now I have a fixed link and have uploaded a local version too. Hopefully
all of these changes will get picked up by Google Scholar.
