# Speko

> Speko is an OpenRouter-style gateway for voice AI: one API for every voice provider. Speko benchmarks STT, LLM, and TTS providers in real time and routes each call to the best provider for your language, latency, and cost target, with automatic failover across the full voice stack (STT, TTS, and speech-to-speech) in 10+ languages.

Documentation lives at https://docs.speko.dev. Machine-readable indexes: https://docs.speko.dev/llms.txt (per-page index) and https://docs.speko.dev/llms-full.txt (full documentation corpus in one file).

## Docs

- [Documentation index for LLMs](https://docs.speko.dev/llms.txt): one-line descriptions of every documentation page
- [Full documentation corpus](https://docs.speko.dev/llms-full.txt): all documentation pages concatenated for LLM context
- [Quickstart](https://docs.speko.dev/quickstart): from sign-up to your first transcribe call in under five minutes
- [MCP quickstart](https://docs.speko.dev/quickstart/mcp): connect Speko to Claude Code, Codex, OpenCode, Cursor, and other AI coding tools
- [How routing works](https://docs.speko.dev/concepts/routing): intent plus benchmark scores produce ranked provider candidates with live failover
- [Failover](https://docs.speko.dev/concepts/failover): how Speko transparently retries against runner-up providers when the primary fails
- [API reference](https://docs.speko.dev/api-reference/introduction): public REST API for the Speko voice gateway
