Who it is for
Pros
- Picks the best model per language instead of one weak default
- Single API keeps integration simple
- Backed by Y Combinator with open gateway options
Limitations
- A free trial is offered, but pricing is not stated and can change
- Requires API integration work, so it is not a no-code tool
- Routing quality depends on the benchmark coverage for your language
What Speko is
Speko is a voice AI routing service operated by Speko Group Inc and backed by Y Combinator. It runs benchmark tests on 56 voice and language models across 10 languages, then routes each session to the model that performs best for that language and use case. The aim is to avoid the common problem where a single model is strong in one language but weak in another. All benchmarked models are reached through one unified API, so developers integrate once instead of writing separate adapters for each provider.
What you can do with it
- Route each voice session to the best model for that language
- Reach many benchmarked models through a single API
- Compare accuracy and cost before choosing a model
- Use the open client gateway with providers such as LiveKit and Pipecat
Who it is for
- Developers adding voice features to an application
- Enterprise teams balancing voice cost against performance
- Voice service providers who want a flexible, open gateway
What to watch out for
A free trial is offered, but pricing is not clearly stated and can change, so confirm terms before you build on it. This is an API service, so it requires integration work rather than a no-code setup. Routing quality depends on how well the benchmarks cover your specific language and scenario, so test with your own audio before launch. Weigh the added routing layer against simply calling one strong model directly. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data.
