Nemotron VoiceChat is NVIDIA's end-to-end model for real-time, full-duplex speech conversations. The official model card describes joint streaming speech understanding and speech generation instead of an ASR, language-model, and TTS cascade. That design targets natural turn taking, interruption handling, and tool calls during a live conversation.
The model card identifies the checkpoint as an 11B speech model and requires a multimodal runtime. The official speech interface and exact revision are therefore part of the model form. A text-only chat adapter does not capture the full VoiceChat identity.
