NVIDIA releases open-weight Nemotron 3 Diarization model
NVIDIA has released Nemotron 3 Diarization, an open-weight, 100M-parameter model for real-time speaker diarization that supports up to eight speakers. The model ranks #1 on VoiceArena's Diarization-Bench leaderboard with a 14.72% Diarization Error Rate (DER), outperforming the next-ranked system by approximately 24% relative reduction.
NVIDIA Magpie TTS adds Arabic, Korean, Portuguese and improves quality
NVIDIA has released an update to its Magpie Multilingual TTS model, expanding support to twelve languages with the addition of Modern Standard Arabic, Korean, and Brazilian Portuguese. The release also includes quality improvements across existing languages through updated training data and architectural changes.
NVIDIA releases NemotronLabs VoiceChat 11B, an open full-duplex speech-to-speech model with ~450 ms turn-taking
NVIDIA has released NemotronLabs VoiceChat 11B, an open 11B parameter end-to-end speech-to-speech model designed for real-time, full-duplex conversation. Unlike cascaded stacks that chain ASR, LLM, and TTS, this unified network performs streaming speech understanding and generation simultaneously, achieving a measured smooth turn-taking latency of 448 ms on Full-Duplex-Bench 1.0.
Nvidia releases Nemotron-Labs-Audex-30B-A3B unified audio-text LLM
Nvidia has released Nemotron-Labs-Audex-30B-A3B, a unified audio-text large language model built on the Nemotron-Cascade-2-30B-A3B text-only MoE backbone. The model extends the original architecture with an audio encoder for inputs and discrete audio tokens for outputs, enabling capabilities in speech recognition, translation, text-to-speech, and audio generation.
NemotronLabs releases VoiceChat, an open full-duplex speech-to-speech model with tool calling
NemotronLabs has introduced VoiceChat, an open-weight full-duplex speech-to-speech model designed to integrate listening, transcription, reasoning, and speaking within a unified streaming architecture. The system combines a streaming speech encoder and decoder-only language model with parallel specialized output streams for agent text and structured function calls, alongside an auxiliary RNN-T branch for incremental user transcription.
