NVIDIA's real-time persona-driven voice dialogue model
PersonaPlex is NVIDIA's open-source, full-duplex speech-to-speech conversational AI model that enables persona control through text-based role prompts and audio-based voice conditioning. Built on the Moshi architecture, it produces natural, low-latency spoken interactions with consistent persona across conversations. The model supports multiple pre-packaged voice embeddings for both natural and varied speaking styles, making it suitable for building interactive voice agents and assistants.
