Announcer/zh-hans

系统广播是一个《传送门2》里面的小人物. 系统广播最为人所知的特点就是他刻板的男性声线. 他的配音演员是Joe Micheals. 系统广播貌似以备用系统的身份前接管了整个光圈科技实验室. 并在GLaDOS不在的情况下维持设施最基本的运行需求. 在传送门2的故事开始之前亦是如此. 在传送门2中，系统广播出现最频繁的时间点是前两章. 系统广播会通过预先录制的语音引导雪儿完成一些实验室.

He is an AI system designed to work in extreme and low power conditions to keep research and testing going, even during "circumstances of potentially apocalyptic significance” so “science can still be done.” Although, unlike many robots and AI in Aperture such as GLaDOS, Cores, or even Turrets, the Announcer does not have a physical presence and displays no hints of sentience. Instead, he rather is or is a part of the basic system of Aperture, his lines similar to computer alerts and triggered in the same fashion (such as deleting a file, indicating problems with the reactor core, etc.) He shows no acknowledgement to the outside the facility, no ability to record results from a test, no recognition of Chell being the one who, no desire to change tests within the facility or create new inventions, or ability to realize that the faulty turret used to sabotage the turret production line was flawed. He can, however, read files, detect life and the overall condition of the facility, operate the sprinkler system, as well as override the main AI in situations like stalemate procedures.

Indicated by his presence behind the scenes of Aperture especially concerning the production of Turrets, the Announcer maintains many ancillary functions that the main AI doesn't overlook but can utilize, and continues to make sure that minuscule problems are taken care of and that the main AI knows of any major problems occurring within Aperture.

Trivia

 * Several unused voice lines indicate that at some point during development of Portal 2, the Announcer's job was to be filled by GLaDOS herself, before ultimately being replaced by Joe Micheals' rendition of the script.
