About Speko
What the tool does and who it's for
Speko is an open infrastructure platform and smart router for voice AI agents, often described as OpenRouter for Voice. It provides a unified API key that centralizes access to multiple speech-to-text (STT), language model (LLM), and text-to-speech (TTS) provider integrations. Speko continuously benchmarks speech and voice models publically for metrics like latency, word error rate (WER), and cost per minute. Based on real-time benchmarks and configurable parameters, Speko dynamically routes audio traffic to the best-performing model stack for specific languages and use cases, providing automatic failover if a primary provider experiences downtime.
