Speko (YC S26) launches OpenRouter for Voice AI, auto-switching STT, LLM, and TTS models

Launch HN: Speko (YC S26) – OpenRouter for Voice AI

Speko, founded by Bek, is a platform that benchmarks and routes between speech-to-text, LLM, and text-to-speech models. It finds the optimal combination based on your constraints (accuracy, latency, cost) and language/region, then switches models automatically via an API and gateway. The gateway can run in BYOK mode with no cloud communication. Speko publishes its benchmarks, including cases where its selections underperform. Since late June, external usage has grown ~25% per week.
