Table 1 Performance metrics for 4 different model configurations, for each of the target animal calls. The range of signal-to-noise ratios in the synthetic training data sets differs between models. Additionally, the “small” models were trained on synthetic data built from a single exemplar of the target call. Bold values indicate top performance.
