NVIDIA Unveils MonsterHouse: An Interactive Halloween Projection Powered by Nemotron Voice Agent
Current overview (not historical)
NVIDIA has released MonsterHouse, a Halloween‑themed interactive projection that uses the Nemotron Voice Agent model to listen to trick‑or‑treaters and respond as a pirate character. The system employs Magpie TTS Zeroshot for voice synthesis and a 4‑bit quantized 4 GB model to drive the dialogue. The project’s creators emphasize that the character design must follow a main conversational flow, respond to visitors’ actual utterances, and track interaction state—all while operating within limited memory and compute budgets. This approach showcases how compact, quantized models can enable real‑time, context‑aware voice interactions in constrained environments.

Report first recorded Oct 31, 02:57
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.
