VoskLib
VoskLib is a Forge library for offline voice recognition in Minecraft 1.20.1, which other mods can call to turn speech into text.
What it does
VoskLib ports the VOSK speech recognition engine to Minecraft. Recognition runs locally on the player's machine, so no internet connection or API key is needed once a model is in place. The library is built for other mods to use, and a player who only wants to speak to the game gains nothing from it without a dependent mod.
Developers can pick between Literal Mode, which accepts a wide vocabulary, and Grammar Mode, which limits recognition to a fixed list of phrases. Recognition runs on a background thread and its results are passed back to the main game thread, so calls into the world happen safely. Partial and final speech results arrive as events on the Forge Event Bus, and a listener can be started or stopped from code.
The library is published for Forge only, for Minecraft 1.20.1, and is open source under the GNU General Public License v3.0 only. It is client-side only, so the server does not need it, and installation means dropping the jar into the mods folder alongside Forge 1.20.1.
Key features
Offline recognition
Speech is converted to text on the local machine using VOSK models, with no network traffic during use.
Literal and grammar modes
A wide vocabulary mode is available next to a constrained mode that only matches a supplied list of phrases.
In-game model manager
Vosk models can be fetched and managed from the mod configuration menu, with a built-in progress bar.
Thread-safe processing
Audio is processed in the background and synchronized with the Minecraft main thread before results reach game code.
Event-based results
Partial and final speech results are fired on the Forge Event Bus, so other mods can react to them as they arrive.
