Open the original- What it measures
- The card adds MUSAN music and noise to the LibriSpeech Clean test set at the stated signal-to-noise ratio (SNR) and reports the WER for each level.
- What it does not show
- Noise is added artificially to clean recordings, so it is not a recording made in a noisy room.
