One API.
Every voice provider.
New voice AI providers launch every week. Stop juggling API keys and rewriting integrations. One API key, every provider, always up to date.
Benchmark. Optimize. Ship.
Test every combination automatically
Speko runs every STT + LLM + TTS combination against your constraints — language, latency, cost — and ranks results in minutes, not weeks.
Always on the best stack
When a new provider launches or prices change, Speko re-evaluates and routes to the optimal combination. Your pipeline stays ahead without code changes.
One API, swap providers in seconds
Single endpoint for all voice providers. Switch from ElevenLabs to Cartesia with a config change. No new API keys, no rewriting integrations.
Ship with confidence, not crossed fingers
