Exploration of Audio Quality Assessment and Anomaly Localisation Using Attention Models
Table 1: Pseudo scores defined in terms of SNR.
['SNR (dB)', 'Pseudo Score']
This is to mimic the definition of scores used for MOS, but does not require human assessors’ to mark each recording as the SNR value of a recording can be set when precisely mixing the original recording with noise signals. In addition, using a set of scores as assessment target might be able to mitigate the impact caused by the use of noise corrupted target values e.g., using the estimated PESQ values as targets in [fu2018]. This is also to compare with the baseline method (Baseline1)[fu2018], which used the same way to compute the utterance-level score.
