Chatterbox.OpenAI
A self-hosted, OpenAI-compatible text-to-speech server.
Chatterbox.OpenAI is a self-hosted, OpenAI-compatible text-to-speech server. It brings high-quality neural speech synthesis in-house behind the same audio API applications already target.
The challenge
Cloud text-to-speech is convenient but comes with recurring cost, data-privacy exposure, network latency and limited control over voices. For anything embedded in an automation or a product, sending text off to a third party on every request is often the wrong trade — but rebuilding against a bespoke local TTS engine means rewriting integrations.
The approach
I wrapped neural TTS models in a server that speaks the OpenAI audio API, so existing clients generate speech locally with no code changes. Custom voices are supported, and because it runs on the owner's own hardware, nothing leaves the machine.
The outcome
A drop-in, private speech engine: the ergonomics of a familiar API, without the cost, latency or data-exposure of a hosted service — easy to slot into existing applications and automations.
