Well im not sure if you have seen this video yet or not but i found it while looking through n4g.com for more halo cod and bf3 news.
I believe it is one of the terminals in Halo: CEA, although its not footage but it reveals 343's new remixed voice which i think sounds nice although i havn't compared it from bungie's version and i haven't heard 343 spark in ages haha, so in my opinion it sounds great. Also note that the terminals are now footage instead of code/writing which i like because i can actually understand whats going on :).
anyway here it is:
the youtube video...enjoy
