# Patchboard — full corpus

## Home
The router for voice AI. Every speech model, benchmarked language by language, wired into one API.
Router is a hosted, provider-neutral STT, LLM and TTS data plane at router.patchboard.online, with
typed contracts and managed routing. 11 of 23 measured STT models are only measured in English.
4 different models win across 9 languages — no single model is best everywhere. Gateway is the
open customer-side runtime for LiveKit and Pipecat: provider-direct streaming, local BYOK
credentials, and optional Patchboard-managed routes.

## Models (/models)
Every model Patchboard has measured, and the catalog entries a request can pin today: 17
speech-to-text models, 13 LLMs, 22 text-to-speech models, and 10 speech-to-speech models, each
ranked by accuracy against cost. Naturalness and error rate are measured per language across 11
languages and 22 studies. Published stacks combine a speech-to-text, LLM, and text-to-speech leg
for real-time phone agents, tool-heavy agents, and natural conversation.

## Voices (/voices)
Measured voice models with published naturalness evidence, and which languages each voice model
is declared for.

## Pricing (/pricing)
$0.09 per minute all-in on Patchboard infrastructure across speech-to-text, LLM and text-to-speech,
or 5% on top of a provider's published rate when routed through Router. $100 in signup credit
applies to every account. Enterprise pricing is custom, locked for the term, with a committed
monthly minimum.
