"Speaker System" redirects here. For the Portal 2 announcer, see Aperture Science Announcement System.
The Aperture Science Speaker System is a public address system used by GLaDOS in Portal to deliver announcements throughout the Aperture Science Enrichment Center. it may also be a part in the Aperture Science Announcement System.
The communications are relayed by speakers spread through the laboratories. The speakers always come in two, and they are sometimes accompanied by a screen (although they could also consist of a speaker and a microphone, possibly to be activated by the small button always present under it). These screens are never used by GLaDOS during the game, hinting they were originally used by the Aperture Science scientists. Instead, they are completely black, with an Aperture Laboratories logo constantly fading from orange to yellow on the bottom left, acting like some sort of screensaver (the button present under the speakers follows the same color fade).
Throughout the Test Chambers, the communications are apparently made in a different way, as no speakers can be found. Security cameras also complete the surveillance.
The devices are often found near doors, for convenience, or possibly because they have other abilities, such as locking doors.
- This is the Portal equivalent of Half-Life’s Black Mesa Announcement System and Half-Life 2’s Breencast.
- Attempting to interact with a Speaker System device will not give any results as Chell is never meant to be able to use one other than listen to GLaDOS.
- Its proper name is unsure. The current name is based on that of the models, "speaker_system" 01 and 02.
- The models come in the speakers alone ("speaker_system_02"), or the speakers and the screen ("speaker_system_01"). They also come in "clean" and "dirty" versions, depending on the locations they are seen.
