 # Readium Speech Server
 
-A remote text-to-speech HTTP service for the [Readium](https://readium.org) ecosystem. Exposes a uniform API for listing voices and synthesizing speech, backed by open neural TTS models running on CPU — no GPU required.
+> [!IMPORTANT]
+> Readium Speech Server is a proof of concept exploring how TTTS (Text to Speech) models can be either hosted or proxied through a single Web service.
+> 
+> This project is not currently production-ready and it's missing key features such as caching or long term storage options.
 
-Designed to pair with [Readium Speech](https://github.com/readium/speech) and any Readium-compatible reading application.
