Voice AI in vogue: Nvidia releases new open transcription model

Nvidia released Nemotron 3.5 Transcribe, a free, open-weight model that transcribes audio in up to 40 languages and translates 31 languages to and from English, alongside version 2 of its open source Granary speech dataset. Nvidia claims it handles recordings up to an hour long, distinguishes up to eight speakers, and beats rivals on benchmarks including Hugging Face's Open ASR Leaderboard; the 30-billion-parameter model runs on a single chip but works with recorded audio, not livestreams. The release targets developers building business meeting and medical transcription apps and joins other recent voice model launches from Mistral, ElevenLabs and Salesforce.
