What it does

Written by AI from the README

Adds more text-to-speech voices to Zotero 10's Read Aloud, including Fish Audio, Azure, OpenAI, Cloudflare, Speechify and local Kokoro servers. Highlights words and sentences in your colours, adds shortcuts, resumes where you stopped and syncs settings and position over WebDAV.

Zotero's own voices and controls are limited. This gives more voices and finer control over listening to papers.

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
