['[BOLD] Database', '[BOLD] Method', '[BOLD] IDR (%)', '[BOLD] MR (%)', '[BOLD] FAR (%)', '[BOLD] IDA (ms)', '[BOLD] Accuracy to ±0.25ms (%)']
The ZFR method can also reach comparable (or even slightly better) results for some databases, but its performance is observed to be strongly sensitive to the considered speaker. In general, these three approaches are respectively followed by the DYPSA algorithm and the HE-based method.
