| dc.description.abstract | Článek se zabývá přínosem detekce změny řečníka (SCD) v úloze diarizace pro telefonní konverzace. Porovnali jsme úspěšnost diarizačního systému založeného na i-vektorech používající naivní segmentaci (konstantní délka okna) a SCD. Experimenty na CallHome korpusu dokázali lepší úspěšnost diarizace s pomocí SCD, ale rozdíly mezi testovanými přístupy byly nakonec smazány použítím resegmentace. | cs |
| dc.description.abstract-translated | The goal of this paper is to evaluate the contribution of speaker change detection (SCD) to the performance of a speaker diarization system in the telephone domain. We compare the overall performance of an i-vector based system using both SCD-based segmentation and a naive constant length segmentation with overlapping segments. The diarization system performs K-means clustering of i-vectors which represent the individual segments, followed by a resegmentation step. Experiments were done on the English part of the CallHome corpus. The final results indicate that the use of speaker change detection is beneficial, but the differences between the two segmentation approaches are diminished by the use of resegmentation. | en |
