Got some time to kill? I've got a slightly amusing task that may interest you. We need some new words for the VOX (the PA system in HL) in order to do some of the cooler replacements.
This job involves taking existing words, loading them into a sound editor, and cutting and mixing them to create the desired new words.
If you're interested, please check out the thread on our forum:
Epicsize.net
It's got links to tutorials on how to do this, a listing of all the words that we need to create (more being added!), and stuff.
Thanks
Mike
