LenguASR Windows demo

Try speech recognition on your own machine. Both the Nemotron and Silero models are included, so you don’t need to install Unreal Editor or download the models separately.

Download Windows demo

Windows x64 · ZIP · 1.13 GB · Speech To Text Models included

Run the demo

  1. Download the ZIP and extract the whole LenguASRDemo folder.
  2. Open that folder and run SpeechPlugin574.exe. Keep the other files and folders alongside it.
  3. Make sure Windows allows desktop apps to use your microphone, then speak to see your words appear in the scene.

Recognition runs locally. For real-time use, you’ll need a modern AVX2-capable CPU. See the system requirements for more details.

To add LenguASR to your own Unreal Engine project, follow Setup & Blueprints.
