Audio stays in region
Speech is generated on SLNG's GPUs in Europe and Australia, so enterprise customers can meet data residency requirements without giving up the model.
Fish Audio S2.1 Pro, in region, on SLNG
SLNG runs Fish Audio S2.1 Pro on in-region GPU infrastructure in Europe and Australia, so audio stays local and latency stays low for production voice agents.
