Open the original- What it measures
- The model card's noise robustness table mixes MUSAN music and noise into the Open ASR sets at the stated signal-to-noise ratio (SNR) and reports the average WER over those eight sets.
- What it does not show
- Noise is added artificially to clean recordings, so it is not a recording made in a noisy room.
