NVIDIA has released Nemotron 3.5 Transcribe, an open-weights speech large language model capable of transcribing audio in 40 languages. This model, featuring approximately 4.3 billion active parameters and a 65,536-token context window, can process audio up to one hour long. It offers various output styles, including verbatim, written form, speaker-attributed, contextual, and translated text, aiming to consolidate separate ASR, diarization, and alignment tools into a single solution. While it leads open-weight models on English and multilingual transcription benchmarks, top commercial APIs still maintain a performance edge. AI
IMPACT Sets new SOTA for open-weight speech transcription models, potentially reducing reliance on multiple specialized tools.
