Open the original- What it measures
- The card describes a 1-billion-parameter Wav2Vec2 model that uses adapter models to transcribe speech in its supported languages. The same card's usage example says the checkpoint can transcribe audio of 1107 different languages, so the card gives two counts. The 1107 count is the one the 2023 paper reports.
- What it does not show
- Listing a language does not mean the model is accurate in it. The card gives the license as CC-BY-NC 4.0, a non-commercial license.
