EN Translator

EN Translator adds client-side live voice transcription and optional translation to Simple Voice Chat on NeoForge 1.21.1. Players can speak in voice chat, have their own client transcribe speech locally, and display transcript or translated chat bubbles in-game.

The base client build includes offline Whisper speech recognition assets, including a bundled NB-Whisper Small model for better Norwegian transcription. Translation is provided through optional regional model pack jars so players can install only the language regions they need.

Privacy And Runtime Behavior

• Voice audio is processed locally on the player client.
• The mod does not upload voice audio to online services.
• The mod does not call external translation APIs during gameplay.
• The mod does not download models at runtime.
• Bundled model files are extracted locally into the Minecraft game directory.
• The distributed jars do not include or launch whisper-cli.exe, whisper-stream.exe, or other Whisper executables.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.227+
• Simple Voice Chat 1.21.1-2.6.15+

Server Notes

Dedicated servers should use the server jar. The server build is relay-only and does not perform local speech recognition or translation. Player clients should install the main client jar plus any desired regional model packs.
