What is 3D AI Studio?

3D AI Studio is a web app that makes 3D models, images and sounds with AI. It runs in your browser, so there is nothing to install.

A template is a saved recipe. It runs a fixed set of AI tools with settings we've already tested, so all you add is a photo or a sentence.

How to describe it

  • Write it the way it's said: punctuation shapes the delivery.
  • Short lines (one or two sentences) sound most natural.
  • Spell unusual names the way they sound.

Good to know: Voices are presets, not clones; for a specific actor's voice, record or license it.

Use the 3D AI Studio MCP to run the "NPC Voice Lines" template (https://www.3daistudio.com/templates/npc-voice-generator) for me.

My line: Ah, a traveller! The road north is dangerous, take this map.
Voice: Wise elder (voice George)

Follow these steps in order. The prompts and settings are the template's own, so use them word for word and only put my line where it says {MY LINE}.

1. Voice the line
Call generate_speech with voice "George", output_format "mp3" and text {MY LINE}, spoken exactly as I wrote it.

After each generation call, keep polling get_generation with its task_id until it completes, then show me the result with show_generation before you start the next step.
