Region and world-part overrides
All integrations route through the SLNG gateway, which supports theX-Region-Override and X-World-Part-Override headers to pin requests to a specific region (for data residency) or to a broader geographic zone like eu or na.
The Cognigy and Jambonz bridges also accept ?region= and ?world-part= query parameters. Use these when the platform does not let you set custom HTTP headers. If you send both, the header wins.
The LiveKit plugin wraps this in a region_override parameter on the STT and TTS classes, so you set it once when you instantiate the model.
See Region and world-part overrides for the full region list and header behavior.
