Custom TTS Reader od BassGaming

Do you have your own OpenAI-compatible Speech endpoint running and want to use it in Firefox?
This is a TTS implementation for the OpenAI API format. It can probably be used for any OpenAI api compliant service but its made for remsky/Kokoro-FastAPI.

Click 'Read Selected Text' in the context menu after highlighting text.

You can change the API URL, API key, speed and voice by clicking the extension icon in the toolbar.
The streaming mode is not working for now since Firefox doesn't support PMC natively.

Since you can host your own speech endpoint, privacy and accessibility are as good as the service you're running.

Personally I recommend using Kokoro FastAPI in a docker container:

Android:
To read text: Mark text -> click the three option dots -> Extensions -> Custom TTS Reader
To access settings: Click the three option dots -> Extensions -> Extension Manager -> Custom TTS Reader -> Settings

Note:
This is just a quick implementation since I couldn't find a similar extension where you could use your own API endpoint anywhere. Feel free to improve it... or not
