Speko

Speko is a voice-AI gateway - "one API for the whole voice stack." It continuously benchmarks speech-to-text, LLM, and text-to-speech providers and routes every call to the best provider for your language, latency, and cost intent, with transparent server-side failover. Developers ship voice agents in minutes over one REST API (no provider keys required, or bring your own), deploying to phone numbers, web widgets, or one-shot transcribe/synthesize/ complete calls. Speko is a Y Combinator (S26) company based in San Francisco, founded by Beknazar Abdikamalov. The platform advertises SOC 2 Type II, HIPAA, and GDPR posture and ships TypeScript and Python SDKs, a browser SDK, a LiveKit adapter, and a hosted MCP server.

Speko publishes 4 APIs on the APIs.io network, including Agents API, Providers API, Telephony API, and 1 more. Tagged areas include Voice, Voice AI, Speech to Text, Text to Speech, and LLM.

The Speko catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Speko’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, support, and 15 more developer resources.
