Speko

Speko is a voice AI routing and infrastructure platform that brings speech-to-text, language models, and text-to-speech together behind a single unified API. Instead of stitching together multiple vendors on your own, you get one consistent interface for the entire voice pipeline.

Every session matters, and model performance varies across languages. Speko benchmarks speech and language models across multiple languages and routes each session to the models best suited to perform well, helping your voice applications deliver reliable quality for users wherever they are.

Speko fits the way you already work. It supports both provider-direct and managed voice workflows, with integrations for LiveKit, Pipecat, OpenAPI, AsyncAPI, and MCP, so you can choose the level of control that matches your team's needs.
