NVIDIA Nemotron 3.5 Transcribe ties for #1 open-weight STT
Efficiency, not just accuracy, is the story: matching top open-weight transcription quality at 4B active parameters cuts inference cost substantially for voice pipelines. Teams building voice agents should shortlist it, since it leads specifically on conversational agent audio (1.8% vs 2.3% for Voxtral Small). The open weights licence also lets companies self-host transcription instead of relying on API vendors.
