@Brendan Jowett I'm setting up a self-hosted agent on an AWS server in Cape Town, South Africa. I've chosen a local SIP Trunk provider, and right now the setup is: • Ears: Cartesia Ink-2 (streaming, native turn detection), Cloud, EU endpoint. • Brain: Claude Haiku 4.5 via Bedrock, af-south • Voice: Cartesia Sonic-3.5, cloned voice, Cloud, EU endpoint. • Conductor: LiveKit Agents 1.6.8, EC2 box • Phone: Switch Telecom trunk Latency: Cartesia is 207–224ms and rock steady; Claude is 900–2,200ms, with variance from Bedrock's shared capacity, not anything I control. I tested prompt padding, caching, and history trimming, and none helped. I am looking at introducing Amazon Nova 2 Sonic, and hoping that will bring my latency down to below 1000 ms. The trade-off will be no cloned voice with no South African accent.
