Custom OpenAI

Use any custom OpenAI-compatible TTS service with OpenReader.

Use this integration when your endpoint is not directly covered by built-in dropdown defaults.

Provider

• Provider: Custom OpenAI-Like
• API_BASE: required (your service base URL)
• API_KEY: set if required by your service

Custom providers should expose:

• GET /v1/audio/voices
• POST /v1/audio/speech

OpenReader setup

1. In OpenReader Settings, choose provider Custom OpenAI-Like.
2. Set API_BASE to your service base URL (typically ending with /v1).
3. Set API_KEY if your service requires authentication.
4. Choose a model and voice supported by your backend.

Notes

Compatibility required

Custom providers must implement OpenAI-compatible TTS endpoints, including GET /v1/audio/voices and POST /v1/audio/speech.

Voice troubleshooting

If voices do not load, verify the /v1/audio/voices response shape and that the endpoint is reachable from the OpenReader server.
