Fastest Voice AI Agent Platform We Tested. Nothing Else Came Close

We evaluated a handful of Voice AI agent platforms with a strict focus on latency—real, measurable, end-to-end responsiveness. Telnyx was the only provider that consistently hit the sub-second performance we needed. Everyone else struggled with noticeable delays, awkward turn-taking, or jitter that completely broke the experience. With Telnyx, the agents feel natural. Responses land quickly, interruptions work the way they should, and the whole interaction feels like a real conversation instead of a laggy IVR. It's the first platform we've tested where we didn't have to compromise on speed or quality. Set-up was straightforward, the docs are solid, and the network reliability shows. If low latency is a priority for your Voice AI agent (and it should be), Telnyx is in a different league in terms of their network.
