Whisper Medium EN (OnnxRuntime/DirectML) for Unity

Summary

Whisper Medium EN (DirectML) is a turnkey Windows x64 Unity package that ships a single native DLL containing the OpenAI Whisper medium.en model accelerated by ONNX Runtime + DirectML. It works offline in the Editor and Windows Standalone builds, enabling local speech-to-text from either audio clips or microphone input (continuous or push-to-talk). Drop it into your project to add language detection and transcription with minimal setup, plus ready-made example scenes and UI.

User scenarios

- You’re building a game and already support controller/keyboard/mouse, but you want speech input for accessibility and hands-free actions.

- You want to create a voice-driven application that reacts to spoken commands without cloud latency.

- You need to transcribe a batch of audio clips dynamically on a machine with no internet access, so you need a light-weight, fast, fully offline solution.
