Half-Life - VOX Announcement System Lines

This is an almost-thorough look at the Black Mesa Automatic Diagnostic and Announcement System’s lines, over half of which were cut and never heard in the final game. Be sure to enable Closed Captions for an on-screen transcript. Of the 10 locations where VOX announcements are defined, only 4 actually implemented them. You must also be standing at very precise locations in order to hear the used VOX lines as they have limited audio range and a 15-135 second delay between each announcement.
