Tips & Best Practices

Get the most out of Wispli Voice Control with these tips.

Speaking Tips

Be Natural

You don't need to memorize exact commands. The AI understands variations:

• "Add a cube", "place a box", "spawn a cube", "put a cube in the scene" — all work
• "Make it bigger", "scale up", "double the size" — all increase scale

Be Specific When Needed

For precise control, include numbers and directions:

• "Move it forward 2 meters" is better than "move it forward a bit"
• "Rotate 45 degrees on the Z axis" is better than "tilt it a little"

Chain Commands

You can give multiple instructions in one sentence:

• "Add a cube and move it up 1 meter"
• "Select all lights and delete them"
• "Add a red point light at 0, 0, 300 with intensity 10000"

Unreal Engine Tips

Units & Coordinates

Concept	Value
1 unit	1 centimeter
1 meter	100 units
Default cube size	100x100x100 cm
Forward	X axis
Right	Y axis
Up	Z axis

Stacking Objects

When stacking, space objects by 100 units (one cube height):

• "Add 3 cubes stacked on each other" → Z: 0, 100, 200

Content Browser

• Paths always start with /Game/
• Folder names are auto-converted to PascalCase
• The plugin detects your active content browser directory

Light Setup

• Default light intensity: 5000 lumens
• Use warm (255, 200, 150) for indoor scenes
• Use cool (150, 200, 255) for outdoor/moonlight
• Directional lights use lux, point/spot lights use lumens

Selection

• Select before acting — most transform commands need a selection
• Use fuzzy search: "select all cubes" finds Cube, Cube_01, MyCube
• If nothing is selected, Wispli tells you instead of failing silently

Productivity Workflows

Level Prototyping

1. Start with the Basic Room macro template
2. Add props with voice: "add a cylinder at 200, 0, 50"
3. Adjust sizes: "select the cylinder" → "scale it to 0.5, 0.5, 2"
4. Add lighting: "add a warm point light at 0, 0, 250"
5. Save: "save all"

Lighting Iteration

1. Place lights with voice: "add a red point light at 300, 0, 200"
2. Adjust: "select the light" → "make it brighter" or "set intensity to 8000"
3. Change color: "change color to warm"
4. Preview: "play in editor" → "stop playing"

Scene Organization

1. Select related actors: "select all cubes"
2. Group them: "group these"
3. Rename: "rename this to WallGroup"
4. Set mobility for performance: "make it static"

Troubleshooting

Command not doing anything?

1. Check the Voice Control panel — is the bridge online and app connected?
2. Check the Command History — does it show the command was sent?
3. Check if the command needs a selection
4. Try rephrasing — the AI may interpret ambiguous phrases differently

Wrong action executed?

• Say "undo" immediately to revert
• For multiple wrong actions: "undo last 3"
• Check the confirmation dialog for details before confirming

Slow response?

• The AI resolver typically takes 1-3 seconds
• Complex multi-command phrases take longer
• Check your internet connection (the AI resolver runs in the cloud)
