Speko
ActiveAI-nativeA router for voice models. One key, every model.
What it does
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.

The router for voice models | Speko
Every voice model is benchmarked in English. Your users don't speak English. Speko measures 61 speech and language models across 10 languages, then routes each session to the one that actually wins.
