Dear Voice AI Architects,
Thinking about using the newly released NVIDIA-Granary speech datasets? Spend one minute with me to see the key issues you should know first.
-
Transcript quality – They use raw Whisper-v3 transcripts. We correct ASR errors with extra metadata.
-
Transcript validation – Whisper often hallucinates. We validate transcripts with our Olign tool, which provides reliable word- and utterance-level confidence scores.
-
Enriched labels – They do not include speaker names or talk-turns. We provide both.
-
Original data – They give you segmented audio only. We deliver full recordings with precise timestamps, and metadata, giving you more flexibility.
-
Customized Services – They leave you on your own. We provide tailored data processing services.
