About Speko
Summary
Speko builds a provider-neutral routing layer for voice AI pipelines. Developers connect via a single API key, and Speko selects the best speech-to-text, LLM, and text-to-speech model for each language and use case based on continuously updated benchmarks. It replaces the manual work of evaluating, integrating, and re-evaluating voice model combinations as the market moves.

API key access with a paid platform tier (pricing listed on site)
Go-to-market
Targets developers and engineering teams building production voice agents, reached through self-serve API key signup and public benchmark tooling at benchmarks.speko.ai.
From the Y Combinator listing
A router for voice models. One key, every model.
Speko is a router for voice models: one API key, and your voice agent runs on the speech-to-text, LLM, and text-to-speech models we measured as best for your language and use case. The measurements are public at benchmarks.speko.ai: we test new models the day they ship and re-route when the numbers change, so you rewrite nothing. We ran this bake-off by hand for four years at Hupo, shipping production voice for Morgan Stanley, Prudential, HSBC, and Grab.
