An interactive haunted house powered by NVIDIA AI for Halloween
In brief
- MonsterHouse is an interactive haunted house that answers visitors in the voice of a grumpy pirate.
- The setup uses Nemotron Voice Agent, Bolt E4B 4GB and Magpie TTS Zeroshot for conversation and voice synthesis.
- The 3D animation of the door is generated by Audio2Face-3D in Unreal Engine, running on a single workstation with two GPUs.
An NVIDIA engineer built an interactive haunted house for Halloween using the company’s Nemotron Voice Agent and related AI models. According to Hugging Face’s blog, the installation responds to visitors in the voice of a grumpy pirate and softens when told “please.”
The project, called MonsterHouse, leverages Nemotron Voice Agent for conversation, Nemotron ASR for speech recognition, the Bolt E4B 4GB model for responses, and Magpie TTS Zeroshot for voice synthesis. A 3D-animated wooden garage door, driven by Audio2Face-3D in Unreal Engine, completes the setup. The whole system runs on a single workstation with two RTX PRO Blackwell GPUs.
This demo highlights NVIDIA’s tools for building local conversational agents and interactive characters, with a focus on resource optimization and response customization.
