Search for speaker identity in historical oral archives

Popis výsledku v původním jazyce

We present our ongoing research focused on speaker recognition in historical oral archives. This research is part of our long-term effort aimed at enabling versatile access to the archive of the Czech Radio (CRo). Based on a manually annotated partitionof the archive, we compiled a database covering a time span of more than 30 years to carry out our experimental study. Hence we were able to investigate the impact of various aspects that make it challenging to process historical data. We show the shiftof scores for target (genuine) speaker trials introduced by the aging effect, the value of the signal-to-noise ratio or by the variable amount of the enrollment and test data. Scores for speaker detection trials were assessed by a system based on the i-vector paradigm and probabilistic linear discriminative analysis. We also assessed the performance of this system using an evaluation database containing contemporary recordings collected over a time span of approximately 4 years. Although
