Run the Windows demo or open the UE project

Run the Windows application

1. Download the model-included Windows demo.
2. Extract the entire archive to a short path such as C:\LAMDemo and launch LAMDemo.exe.
3. Choose a speech button on the left, or press 1–6. Expressions and audio play after analysis completes.

The model, plugin, character, and six speech samples are included. You do not need the UE editor or Python. If the VC++ runtime is missing, run the included Engine/Extras/Redist/en-us/vc_redist.x64.exe.

Controls

Key	Action
1–6	Select a speech sample
Space	Pause / resume
R	Replay from the beginning
V / − / ＋	Mute / lower volume / raise volume
O / F	Switch output submix / fade out and stop
M / I	Start or stop microphone / cycle 100, 333, 1000 ms inference intervals
Alt + F4	Exit

Microphone input needs Windows microphone permission. The plugin does not monitor the captured audio through speakers. Long-running use with a physical microphone remains unverified.

1. Select audio using buttons 1–6. Their labels classify the speech samples.
2. Space pauses/resumes; R replays from the beginning.
3. Inspect volume, output and live status. The values belong to the existing capture, not a new measurement.

Character: hinzka / VRoid and pixiv. Speech: JVNV / litagin. See the licenses page for usage conditions.

Release demo versus Blueprint source demo

v0.3.0 includes the Blueprint demo

The v0.3.0 ZIPs use Demo f3b6f13 and include the Blueprint UI and analysis flow below. The older v0.2.0 recording predates this migration. Latest public Demo 9dee71d only advances the plugin reference. See the release manifest.

Start with 02_Analyze_And_Play in BP_FaceDemo: SelectSample → cancel previous work → Analyze SoundWave Async → Completed → Play Expression Clip.

Blueprint	Responsibility
BP_FaceDemo	Analysis, playback, input, state events
BP_FaceDemoHUD	Canvas-based UI and click handling
BP_FaceDemoGameMode	Selects the HUD
ABP_Face52	Applies expressions with Apply LAM ARKit Curves

These assets live under Content/LAMFaceDemo. To move the demo to another project, install the plugin and use Content Browser’s Migrate command. Keep the asset attribution and licenses. You do not need the demo assets when integrating your own character.

Viseme and baked-clip examples

v0.3.0 also includes five-vowel / Oculus template examples and baked-clip examples. Normal face-demo startup still uses ARKit 52. For a vowel rig, inspect /Game/LAMVisemeExamples/ABP_LAMVisemes and its Fcl_MTH_A/I/U/E/O targets. OpenFaceFX and TalkingHead examples use ABP_OpenFaceFX and ABP_TalkingHead in that folder. The test script switches the mesh and AnimBP only when the relevant test flag is supplied; these are not extra keyboard modes in the normal HUD.

See Viseme setup, saved-clip examples, and the v0.3.0 validation record.
