NVIDIA Launches MonsterHouse, a Haunted‑House Projection Powered by Nemotron Voice Agent

NVIDIA unveiled MonsterHouse, an interactive Halloween projection that turns a garage door into a grumpy pirate‑styled house. The system uses NVIDIA’s Nemotron Voice Agent to listen to visitors via Nemotron Speech ASR, generate responses with the Nemotron 3.5 Bolt E4B 4GB language model (enhanced by a LoRA adapter), and produce voice output with Magpie TTS Zeroshot. Audio2Face‑3D animates the door’s wooden mouth in Unreal Engine 5, while Nemotron 3 Nano Omni, YOLO, and ByteTrack track and describe visitors. The entire setup runs on a single workstation equipped with an NVIDIA RTX PRO 6000 Blackwell Max‑Q and an RTX PRO 4000 Blackwell. The demo showcases how open‑source AI models can create immersive, location‑based experiences on modest hardware.
