About
Speko is a router for voice AI that benchmarks speech models across multiple languages and automatically selects the best one for each session. It provides a single API combining speech-to-text, language models, and text-to-speech with public benchmarks and runtime availability. Speko helps developers building voice agents ensure their applications use the best-performing models for their users' languages.
Use Cases
- Voice agent developers who need the best speech model for non-English languages
- Teams building multilingual voice applications who want to avoid benchmarking models themselves
Pricing
Router plan adds 5% markup on provider rates with $10 signup credit. Speko infrastructure plan costs $0.09 per minute all-in for speech-to-text, LLM and text-to-speech. Enterprise plan available with custom pricing.
