The core of the algorithm is based on perceptual time-quefrency analysis with a precision of 10 ms. Performance levels achieved to date on 14+ hours hand-labelled dataset have shown positive impact of excitation frequency on temporal synchronisation (98.19\% precision for 5 s recordings) and confidence estimation (99.08\% precision with 100\% recall for 5 s recordings). The results surpass the performance of fast cross correlation while keeping lower system requirements.}, pdf = {https://publications.idiap.ch/attachments/reports/2011/Korchagin_Idiap-RR-20-2011.pdf} }
