Making a faceposer scene be heard everywhere

[hen7]

Hey, I have a few vcd scenes in my mod and I'm trying to make them hear-able everywhere around the map, like how ambient_generic have the "play everywhere" flag.
I remember that in portal for example Glados normal speech was heard everywhere, while the "escape speech" didn't and used env_microphone.
Any info is welcome, thank you.

Try Env_speaker?

Announcement Speaker, used in several maps it uses the NPC response context system. You can specify time between announcements. When it makes an announcement, it looks at its Context rule script, chooses the best rule (Response Contexts and Concept name are used here.), then dispatches a response which could be a .vcd scene that controls an NPC, a sentence, or just a sound. See Response System for more information about context rule script grammar.

Doesn't work, also I don't think it's the right way to do it, even if it will work, in Portal for instance there wasn't any fancy Env_speakers, thanks though.
Anyone else?
