OpenRouter for Voice AI: one API, every call on the best speech model
speko.ai/?utm_source=ycombinator&utm_medium=profile
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. Speko is a Y Combinator company (Summer 2026). YC-listed status: Active.
