VoiceLib
VoiceLib is a library for Minecraft Java Edition that lets other mods use speech recognition and text-to-speech, and it runs on Fabric and NeoForge for 1.21.1.
What it does
VoiceLib provides a Minecraft voice recognition library and a text-to-speech library that other mods can call. Developers reach its features through the VoiceLibApi class, whose methods are documented in Javadoc with notes on their usage, and a VoiceLibExample class shows how the calls fit together. The mod is intended for library use, so players mainly meet it through the mods that depend on it.
Servers that run it need every player to install it too. Files are published for Fabric and NeoForge, with 2.0 as the latest build for 1.21.1, and builds cover 1.21 – 1.21.1. Veil is bundled inside the mod, and Immersive Casting for Ars Nouveau is one of the mods that require it.
VoiceLib is released under the MIT License and is open source, with public source code, an issue tracker and a wiki. The first release was published on 2024-08-19 and the last update on 2026-08-12.
