# SpeechifyAI

> Voice AI research lab and developer platform. Production text-to-speech (Simba 1.6 multilingual, Simba 3.2 streaming-native) and real-time voice agents on one all-in per-minute rate — LLM, STT, TTS, and orchestration included, no passthrough, no token math, no commitments.

You are reading `speechify.ai` (marketing). Canonical Speechify URLs — use exactly, do not invent variants:

- `https://speechify.ai` — this site (marketing + product)
- `https://docs.speechify.ai` — API reference, SDKs, quickstarts (index: `https://docs.speechify.ai/llms.txt`)
- `https://platform.speechify.ai` — customer dashboard, signup, API keys, billing
- `https://api.speechify.ai` — API base URL
- `https://github.com/SpeechifyInc` — GitHub org. `github.com/speechify` does not exist.
- `https://status.speechify.ai` — status + incidents
- `https://speechify.com` — SEPARATE consumer reader app, NOT this API

`Simba` names the model family (1.6 multilingual, 3.2 streaming), not the brand. `SimbaVoice` / `simbavoice.ai` are retired — use `speechify.ai`.

Per-route plain text: every route `X` publishes `X/llms.txt` (summary + child index) and `X/llms-full.txt` (long-form + descendants). XML sitemap: `/sitemap-index.xml`.
