Black Mesa Announcement System/Quotes

	This is a quote article.
	This article is a transcript of all of the quotes from a given character or entity. Unless noted otherwise, these transcripts are sourced directly from the official scripts, closed captions, or internal text data with only minimal modifications for typos and formatting purposes.

	You can help clean up this page by correcting spelling and grammar, removing factual errors and rewriting sections to ensure they are clear and concise, and moving some elements when appropriate. Please notify the administrators before removing this template.

The following is a list of quotes from the Black Mesa Announcement System. Included are also the many cut Half-Life announcements only found in the file sentences.txt.

The announcements are generated in real-time from a total of 608 separate words, with occasionally blank sound files for pauses between words and notification sounds when needed. The sentences have been reassembled from scratch for the wiki following the lists found in sentences.txt, along with some announcements not listed in the file. Also included are the notification sounds; in some instances they have a different pitch, which is not reproduced here.
